  • PI Film vs PET Film: Which Insulating Film Is Better for Your Electronics Application?

    Introduction

    Polyimide (PI) film and polyester (PET) film are the two most widely used insulating film materials in the electronics and electrical industries. PI film is renowned for its exceptional high/low-temperature performance and dimensional stability, finding extensive use in flexible printed circuits (FPC), aerospace wire insulation, and high-end motor insulation. PET film dominates consumer electronics, packaging, and general industrial insulation with its excellent cost-performance ratio. The price gap between the two can reach 5–20×, making material selection critically impactful on cost control. This article provides a systematic comparison across four dimensions: temperature resistance, electrical properties, mechanical properties, and cost.

    1. Material Properties Comparison

    Property PI Film (Polyimide) PET Film (Polyester)
    Density (g/cm³) 1.38–1.43 1.38–1.41
    Thickness Range (μm) 12.5–125 6–350
    Tensile Strength (MPa) 170–230 150–220
    Elongation at Break (%) 40–80 80–150
    Elastic Modulus (GPa) 2.5–3.5 3.0–4.5
    Long-term Service Temp. (°C) –269 to +400 –70 to +150
    Short-term Heat Resistance (°C) ~500 (before carbonization) ~200 (significant shrinkage)
    Dielectric Strength (kV/mm) 220–300 280–350
    Dielectric Constant (1kHz) 3.4–3.8 3.0–3.4
    Dissipation Factor (1kHz) 0.001–0.005 0.002–0.020
    Volume Resistivity (Ω·cm) >10¹⁶ >10¹⁶
    Water Absorption (%) 1.5–3.0 0.4–0.8
    Radiation Resistance Excellent (space-grade) Poor (UV degradable)
    CTE (×10⁻⁶/°C) 20–50 (anisotropy controllable) 15–30 (MD) / 60–100 (TD)
    Typical Price (USD/kg) 28–85 2–6

    2. In-Depth Performance Comparison

    2.1 Temperature Resistance

    The most outstanding characteristic of PI film is its extreme temperature stability. It can be used long-term from –269°C (liquid helium temperature) to +400°C, and can withstand temperatures above 500°C for short periods (before carbonization), with a UL temperature index of 220°C (Class H insulation material). PET film’s long-term service temperature is only –70 to +150°C; noticeable thermal shrinkage begins above 160°C, and melting/flow occurs above 180°C. This gap determines PI’s irreplaceability in extreme temperature environments such as aerospace, automotive engine compartments, and downhole logging.

    2.2 Electrical Insulation Properties

    Both films achieve dielectric strengths above 200 kV/mm, ranking among excellent insulation grades. PET’s dielectric strength is slightly higher than PI (280–350 vs. 220–300 kV/mm), giving it an edge in general electrical insulation. PI’s dielectric constant (3.4–3.8) is slightly higher than PET (3.0–3.4), and its dissipation factor is also somewhat higher, but the impact on signal integrity in high-frequency/high-speed circuits remains within an acceptable range. Notably, PI film’s dielectric properties remain stable across a wide temperature range (–200 to +300°C), which PET cannot match.

    2.3 Mechanical Properties & Dimensional Stability

    PI film’s elastic modulus (2.5–3.5 GPa) is slightly lower than PET (3.0–4.5 GPa), but its elongation at break is also lower (40–80% vs. 80–150%), exhibiting higher dimensional stability — after 2 hours at 230°C, PI’s dimensional change rate is <0.3%, while PET shows significant shrinkage. PI's coefficient of thermal expansion (CTE) can be tuned via molecular design to approach that of metals (~20×10⁻⁶/°C), which is critical in high-density interconnect (HDI) and chip packaging for reducing thermally induced stress failures.

    2.4 Water Absorption & Environmental Durability

    PI film’s water absorption (1.5–3.0%) is significantly higher than PET (0.4–0.8%), which is PI’s primary weakness — after moisture absorption, dielectric constant increases and slight dimensional expansion occurs, requiring pre-baking treatment in high-precision applications. PET has low moisture absorption and performs more stably in humid environments. However, in radiation resistance, PI film performs exceptionally well (withstanding doses >10⁷ Gy), making it suitable for space environments; PET degrades rapidly under UV and γ-ray exposure, rendering it unsuitable for outdoor or aerospace applications.

    3. Application Scenarios

    3.1 Where PI Film Excels

    • Flexible Printed Circuits (FPC): Smartphones, wearables — leveraging high-temperature resistance (SMT reflow 260°C) and dimensional stability
    • Aerospace wire & cable insulation: Satellites, rockets — leveraging extreme temperature resistance, radiation resistance, and low outgassing
    • Motor and transformer insulation: NEV drive motors (Class H+ temperature rating) — leveraging long-term 200°C+ temperature capability
    • Semiconductor packaging: COF (Chip-on-Film), TAB carriers — leveraging low CTE matching silicon chips
    • Thermal/acoustic insulation: High-speed rail, aircraft interiors — leveraging low outgassing and flame resistance (self-extinguishing)
    • High-temperature labels/tapes: PCB processing carriers — leveraging chemical resistance + high-temperature resistance

    3.2 Where PET Film Excels

    • Consumer electronics insulation & structure: Cell battery separators, capacitor films — leveraging high dielectric strength and low cost
    • General wire & cable insulation: Appliance wiring, low-voltage cables — leveraging good insulation and cost-performance
    • Industrial tape substrates: Electrical tapes, packaging tapes — leveraging high tensile strength and low cost
    • Food packaging: Retort pouches, vacuum packaging — leveraging high barrier properties, transparency, and heat-sealability
    • Solar panel backsheets: PV modules — leveraging weather resistance (with coated treatment) and insulation
    • Flexible display substrates (modified PET): Low-end flexible screens — leveraging high transparency and low cost

    3.3 Hybrid Approach

    In certain applications, PI and PET can be used in combination. Typical example: FPC stiffeners — PI in dynamic bending zones, PET in static reinforcement zones, balancing reliability and cost. Another case: motor insulation systems — PET for slot insulation (cost-optimized), PI for inter-turn insulation (temperature guarantee); hybrid design can reduce material costs by 30–50%.

    4. Cost-Effectiveness Assessment

    Dimension PI Film PET Film
    Raw material price (USD/kg) 28–85 2–6
    25μm film unit price (USD/m²) 5.5–17 0.4–1.4
    Processing method Cast + biaxial stretching / thermal imidization Biaxial stretching (mature process)
    Processing difficulty High (narrow process window, low yield) Low (extremely mature process)
    Material utilization Medium–Low High
    Part life (relative) High (3–10× PET) Baseline
    Replaceability Irreplaceable in extreme conditions Partially replaceable by PI/PA

    PI film costs 10–20× more than PET — the biggest barrier in material selection. However, from a TCO perspective: in applications requiring >150°C temperature resistance, radiation resistance, or extreme dimensional stability, PI is the only choice — no “alternative” exists. In general applications with <130°C temperature requirements, PET has sufficient performance headroom, and using PI constitutes over-engineering. The key decision criteria: Does the operating temperature exceed 150°C? Is extreme dimensional stability required? Is it used in space/radiation environments? If any answer is “yes,” PI is irreplaceable; if all are “no,” PET is the optimal solution.

    5. Selection Guide

    Operating Condition Recommended Material Rationale
    FPC (smartphone/wearable) PI film (25–50μm) Withstands SMT temp, dimensionally stable
    Aerospace/military wire insulation PI film Extreme temp + radiation resistant
    NEV drive motor insulation PI film (NMN/DMD structure) Class H+ temperature rating
    General motor/transformer insulation (<130°C) PET film (NMN structure) Optimal cost, adequate performance
    Appliance wire & cable insulation PET film Best cost-performance ratio
    Capacitor dielectric PET film (down to 2μm) High dielectric strength + low loss
    PV backsheet PET film (weather-resistant coating) Weathering + insulation + moderate cost
    High-end flexible display substrate PI film (transparent PI/CPI) High temp + foldable
    General industrial tape PET film High strength + low cost
    Need high temp + cost balance PEN film (PET upgrade) ~200°C rating, price between PI and PET

    Conclusion

    PI film and PET film are two important nodes in the electronic insulation material spectrum, not competitive substitutes. If your application involves “high temperature (>150°C) + extreme environment + high dimensional stability,” choose PI film. If your application is “ambient/medium temperature + general electrical insulation + cost-sensitive,” choose PET film.

    For cost-sensitive applications requiring moderate temperature resistance, PEN (polyethylene naphthalate) film is a worthwhile compromise — temperature resistance up to 200°C, priced at 1/3–1/2 of PI, with performance between PI and PET.

    Procurement advice: Clarify the part’s maximum operating temperature (note: material temperature, not ambient), use it to screen against the two films’ long-term temperature limits; then evaluate lifespan requirements (PI life is typically 3–10× that of PET); finally perform a TCO calculation. Don’t blindly select PI because of its “premium” label, and don’t risk using PET in high-temperature conditions because of its low cost — let data drive the decision.

  • PI薄膜 vs PET薄膜：哪种绝缘薄膜更适合你的电子应用？

    引言

    聚酰亚胺（PI）薄膜和聚酯（PET）薄膜是电子电气行业应用最广泛的两种绝缘薄膜材料。PI薄膜以优异的耐高低温性能和尺寸稳定性著称，广泛用于柔性电路板（FPC）、航天电线绝缘和高端电机绝缘；PET薄膜则以优异的性价比在消费电子、包装和一般工业绝缘中占据主导地位。两者的价格差距高达5–10倍，选材决策对成本控制影响巨大。本文从耐温性、电气性能、机械性能和成本四个维度进行系统对比。

    一、材料特性对比表

    性能指标 PI薄膜（聚酰亚胺） PET薄膜（聚酯）
    密度 (g/cm³) 1.38–1.43 1.38–1.41
    厚度范围 (μm) 12.5–125 6–350
    拉伸强度 (MPa) 170–230 150–220
    断裂伸长率 (%) 40–80 80–150
    弹性模量 (GPa) 2.5–3.5 3.0–4.5
    长期使用温度 (°C) -269 ~ +400 -70 ~ +150

    CTE (×10⁻⁶/°C) 20–50（各向异性可控） 15–30（纵向）/ 60–100（横向）
    典型价格 (元/kg) 200–600 15–40

    二、性能参数深度对比

    2.1 耐温性能

    PI薄膜最突出的特性是极端温度稳定性。可在-269°C（液氦温度）至400°C长期使用，短时间内可承受500°C以上高温（至碳化前），UL温度指数达220°C（E级绝缘材料）。PET薄膜长期使用温度仅为-70~150°C，超过160°C开始出现明显热收缩，180°C以上熔体流动。这一差距决定了PI在航空航天、汽车发动机舱、深井测井等极端温度环境中的不可替代性。

    2.2 电气绝缘性能

    两种薄膜的介电强度均达到200 kV/mm以上，均属优秀绝缘等级。PET的介电强度略高于PI（280–350 vs 220–300 kV/mm），在一般电气绝缘中更有优势。PI的介电常数（3.4–3.8）略高于PET（3.0–3.4），介质损耗也稍高，但在高频高速电路中对信号完整性的影响仍属可接受范围。值得注意的是，PI薄膜的介电性能在宽温度范围内（–200~+300°C）保持稳定，这是PET无法比拟的。

    2.3 机械性能与尺寸稳定性

    PI薄膜的弹性模量（2.5–3.5 GPa）略低于PET（3.0–4.5 GPa），但断裂伸长率更低（40–80% vs 80–150%），表现出更高的尺寸稳定性——在230°C高温下处理2小时，PI的尺寸变化率<0.3%，PET则出现显著收缩。PI的热膨胀系数（CTE）可通过分子设计调控至接近金属（20×10⁻⁶/°C），在高密度互连（HDI）和芯片封装中至关重要，可有效降低热循环导致的应力失效。

    2.4 吸水率与环境耐受性

    PI薄膜的吸水率（1.5–3.0%）显著高于PET（0.4–0.8%），这是PI的主要短板——吸湿后介电常数升高，尺寸微膨胀，在高精度应用中需进行预烘处理。PET吸水性低，在潮湿环境中表现更稳定。但在耐辐射性上，PI薄膜表现极佳（能承受>10⁷ Gy剂量），适合太空环境；PET在UV和γ射线照射下迅速降解，不适合户外或航天应用。

    三、应用场景分析

    3.1 PI薄膜优势场景

    • 柔性印刷电路板（FPC）：智能手机、可穿戴设备——利用耐高温（SMT回流焊260°C）、高尺寸稳定性
    • 航天电线电缆绝缘：卫星、火箭——利用耐极端温度、耐辐射、耐真空释气
    • 电机和变压器绝缘：新能源车驱动电机（耐温等级H级以上）——利用长期200°C+耐温能力
    • 半导体封装：COF（Chip-on-Film）、TAB载带——利用低CTE匹配硅芯片
    • 隔热隔音：高铁、航空器内饰——利用低释气、阻燃（自熄性）
    • 耐高温标签/胶带：PCB制程载具——利用耐化学+耐高温

    3.2 PET薄膜优势场景

    • 消费电子绝缘与结构：手机电池隔膜、电容膜——利用高介电强度、低成本
    • 电线电缆一般绝缘：家电布线、低压电缆——利用良好绝缘性和性价比
    • 工业胶带基材：电工胶带、包装胶带——利用高拉伸强度和低成本
    • 食品包装：蒸煮袋、真空包装——利用高阻隔性、透明度、热封性
    • 太阳能电池背板：光伏组件——利用耐候性（经涂层处理）、绝缘性
    • 柔性显示基板（改性PET）：低端柔性屏——利用高透明度和低成本

    3.3 混合方案

    在某些应用中，PI和PET可以组合使用。典型例子：FPC补强板 — 动态弯折区域使用PI，静态补强区域使用PET，兼顾可靠性和成本。另一案例：电机绝缘系统 — 槽绝缘用PET（成本优化），匝间绝缘用PI（耐温保障），混合设计可降低材料成本30–50%。

    四、成本效益评估

    评估维度 PI薄膜 PET薄膜
    原料价格 (万元/吨) 20–60 1.5–4
    25μm薄膜单价 (元/m²) 40–120 3–10
    加工方式 流延+双向拉伸/热亚胺化 双向拉伸（成熟工艺）
    加工难度 高（工艺窗口窄，良率低） 低（工艺极为成熟）
    材料利用率 中–低 高
    零件寿命（相对值） 高（3–10× PET） 基准
    可替代性 极端工况无可替代 部分场景可被PI/PA替代

    PI薄膜的价格是PET的10–20倍，这是选材时最大的障碍。但从TCO角度来看：在要求耐温>150°C、耐辐射或极端尺寸稳定的应用中，PI是唯一选择，不存在”替代方案”。在耐温<130°C的一般应用中，PET的性能冗余度充足，使用PI属于过度设计。关键判断依据：工况温度是否超过150°C？是否要求极端尺寸稳定性？是否用于太空/核辐射环境？任一答案为”是”，则PI不可替代；全部为”否”，则PET是最优解。

    五、选型建议

    工况条件 推荐材料 理由
    FPC（智能手机/可穿戴） PI薄膜（25–50μm） 耐SMT高温，尺寸稳定
    航天/军工电线绝缘 PI薄膜 耐极端温度+耐辐射
    新能源车驱动电机绝缘 PI薄膜（NMN/DMD结构） 耐温等级H级以上
    一般电机/变压器绝缘（<130°C） PET薄膜（NMN结构） 成本最优，性能满足
    家电电线电缆绝缘 PET薄膜 性价比最高
    电容器介质 PET薄膜（更薄至2μm） 高介电强度+低损耗
    光伏背板 PET薄膜（耐候涂层改性） 耐候+绝缘+成本适中
    高端柔性显示基板 PI薄膜（透明PI/CPI） 耐高温+可折叠
    一般工业胶带 PET薄膜 高强度+低成本
    需同时满足耐高温+低成本 PEN薄膜（PET升级替代） 耐温~200°C，价格介于PI和PET之间

    结论

    PI薄膜和PET薄膜是电子绝缘材料谱系中的两个重要节点，而非竞争替代关系。如果工况涉及”高温（>150°C）+ 极端环境 + 高尺寸稳定性”，选PI薄膜；如果工况是”常温/中温 + 一般电气绝缘 + 成本敏感”，选PET薄膜。

    对于成本敏感但又需要一定耐温性的场景，PEN（聚萘二甲酸乙二醇酯）薄膜是值得考虑的折中方案——耐温可达200°C，价格是PI的1/3–1/2，性能介于PI和PET之间。

    采购建议：明确零件的最高工作温度（注意是材料温度，不是环境温度），对照两种薄膜的长期耐温上限做初筛；再评估寿命要求（PI寿命通常是PET的3–10倍）；最后做TCO计算。不要因PI的”高端”标签而盲目选用，也不要因PET的低成本而在高温工况中冒险——让数据驱动决策。

    1. Production Scale and Mass Production Capability

    • Annual capacity: >1,000 t/y indicates stable mass production (not pilot line)
    • Stable precursor supply: Do they produce their own PAN precursor (polyacrylonitrile), or rely on external sourcing? Self-produced precursor ensures better quality control.
    • Oxidation and carbonization furnace capacity: T1000 requires precise temperature control (±1°C) in the carbonization zone (1,300–1,600°C).

    2. Quality Certifications and Aerospace Qualification

    • ISO 9001:2015 minimum; AS9100 D preferred for aerospace
    • NADCAP accreditation for chemical processing (sizing, surface treatment)
    • Airbus/Boeing material qualification (BMS 8-276, Airbus ABS 0771) — only a few Chinese suppliers have achieved this in 2026
    • Customer-specific qualifications: COMAC (C919, C929), AVIC, or defense procurement certification

    3. R&D and Customization

    • Can they tailor sizing formulation for your specific resin system (epoxy, BMI, polyimide, PEEK)?
    • Do they offer hybrid tow (T1000 + glass fiber or aramid) for optimized cost/performance?
    • Custom surface treatment (increased roughness for better adhesion, or smooth for surface finish applications)?

    4. Supply Chain Resilience

    • Dual-source precursor arrangement (PAN precursor supply disruption is a key risk)
    • Energy supply stability (carbon fiber production is energy-intensive: ~120–150 kWh/kg)
    • Geographic diversification: Some Chinese suppliers now have overseas production (Southeast Asia) to mitigate trade restrictions

    Application Scenarios and Material Selection

    Aerospace Primary Structures

    Require T1000 with epoxy-compatible sizing and full traceability. Typically use 12K tow in unidirectional prepreg layup. Procurement volume: 5–50 t/year for Tier 1 aero suppliers. Qualification cycle: 12–18 months.

    Defense and UAV

    T1000 for missile casings and UAV airframes where weight savings >30% vs. aluminum. Typically use woven fabric (2×2 twill, 200–300 g/m²). Procurement volume: 1–20 t/year. Export control compliance (ITAR, Chinese export control) is critical.

    Premium Automotive

    T1000 for chassis components and drive shafts where high fatigue resistance is required. Cost-sensitive, so large tow (24K) T1000 or T1000/T800 hybrid may be used. Procurement volume: 50–500 t/year for major EV/luxury car makers.

    Sporting Goods

    T1000 for high-end racing bicycles, golf shafts, and tennis rackets. Typically use 12K tow or woven fabric. Aesthetics matter (surface finish), so suppliers with excellent surface quality are preferred. Procurement volume: 10–100 t/year.

    Procurement Strategy for T1000 Carbon Fiber in 2026

    1. Qualify at least two suppliers: T1000 production is complex and sensitive to process variations. A dual-source strategy mitigates supply risk from equipment failure, energy restrictions, or trade policy changes.
    2. Negotiate annual framework with price adjustment formula: Raw material (PAN precursor, epoxy resin) and energy costs fluctuate. Link pricing to published indices (e.g., acrylonitrile spot price) with quarterly adjustment.
    3. Request mechanical property data (tensile, ILSS, compressive strength) for each batch: T1000 is a high-performance material—incoming QC should verify strength and modulus. Require CoA with each shipment.
    4. Plan for 6–10 week lead time: T1000 is not off-the-shelf. Custom sizing and surface treatment add 2–4 weeks. Place orders 3–4 months before production start.
    5. Consider total cost of ownership, not just unit price: T1000 scrap rate in processing (prepreg layup, curing) can be 5–15%. A supplier with better surface quality and sizing compatibility reduces scrap and rework costs.
    6. Audit the supplier’s precursor line and carbonization process: T1000 quality starts with PAN precursor (molecular weight distribution, comonomer content). Visit the supplier’s production site to audit their precursor QC and carbonization temperature control system.
