  • Complete Guide to PEEK Rod Properties Applications and Supplier Selection

    PEEK (Polyether Ether Ketone) rod is one of the most sought-after high-performance thermoplastics in precision engineering. If you are evaluating PEEK rod for a demanding application, here is what you need to know.

    What Makes PEEK Rod Exceptional

    PEEK occupies a unique position in the engineering plastics hierarchy. It delivers the thermal stability of some thermosets while maintaining the fabrication flexibility of thermoplastics, and it does so at continuous service temperatures up to 250C.

    Key mechanical properties: tensile strength 90-100 MPa at room temperature, flexural modulus 3.6 GPa (stiff yet machineable), notched impact 4.5 kJ/m2 (survives sudden mechanical shocks), water absorption 0.5 percent after 24h immersion (dimensionally stable), chemical resistance to most acids, bases, and organic solvents up to 200C.

    Grades Available at LiiFoo

    VICTREX PEEK 450G (Virgin Grade): Unfilled, natural color. Highest elongation and toughness. Ideal for general engineering, bushings, and insulators.

    PEEK-GF30 (30% Glass-Filled): 30% glass fiber reinforcement. Higher stiffness and creep resistance at elevated temperatures. Preferred for structural components in aerospace interiors.

    PEEK-CA30 (Carbon-Filled): 30% carbon fiber reinforcement. Lowest coefficient of friction, highest thermal conductivity. The go-to grade for seals, piston rings, and bearing surfaces in semiconductor equipment.

    Common Applications by Industry

    Semiconductor: Wafer carriers, CMP rings, insulator sleeves. Requires carbon-filled grades with low particle generation and high purity.

    Aerospace: Interior brackets, cable clips, thermal insulators. Virgin or glass-filled grades meet FAA flammability requirements.

    Oil and Gas: Drill bit components, valve seats, downhole seals. Carbon-filled grades for wear resistance in high-pressure environments.

    Medical: Instrument handles, surgical tool components. FDA-compliant grades available with USP Class VI certification.

  • PEEK材料迎来爆发前夜：从商业航天到人形机器人的万亿级应用蓝图

    摘要：PEEK（聚醚醚酮）被誉为”塑料之王”，凭借耐高温、耐腐蚀、轻量化等优异性能，正在商业航天、人形机器人、医疗器械、汽车制造等领域加速渗透。2026年，随着国产化产能释放和新兴应用场景打开，PEEK材料正处于产业爆发的前夜。

    一、PEEK是什么？为什么被称为”塑料之王”

    PEEK（Polyetheretherketone，聚醚醚酮）是一种半结晶性的特种工程塑料，属于聚芳醚酮（PAEK）家族中的核心品种。它的核心单体原料为4,4′-二氟二苯甲酮（DFBP），由英国ICI公司于1978年首次实现工业化生产。

    PEEK之所以获得”塑料之王”的美誉，源于其近乎全面的性能均衡性：

    • 耐热性突出：长期使用温度可达250°C，玻璃化转变温度143°C，熔点343°C
    • 力学性能优异：抗拉强度90-100MPa，兼具高刚性和良好的韧性
    • 化学稳定性极佳：除浓硫酸外，几乎不受任何化学试剂腐蚀
    • 阻燃性能天然：无需添加阻燃剂即可达到UL94 V-0级别
    • 轻量化优势明显：密度约1.3 g/cm³，仅为铝合金的一半、钢铁的六分之一
    • 生物相容性良好：通过多项医疗级认证，可长期植入人体

    这些特性的组合，使PEEK能够在传统金属、陶瓷和其他工程塑料难以胜任的极端环境中稳定工作。

    二、核心技术进展：国产化突破与改性创新

    长期以来，全球PEEK市场被英国Victrex（威格斯）、比利时Solvay（索尔维）和美国DuPont（杜邦）等国际巨头垄断。但近年来，中国企业在PEEK国产化方面取得了实质性突破。

    新瀚新材（301076）作为国内DFBP核心原料供应商，其产品已广泛应用于商业航天和人形机器人领域。江苏中研等企业则打通了从树脂合成到改性料的全产业链，具备年产500吨PEEK树脂及改性料的产能，提供5大系列80多个牌号的产品。

    在改性技术方面，行业已开发出高耐磨、高强度、耐高温、低摩擦系数、耐冲击、耐疲劳、高流动性等不同性能方向的专用牌号。以鹏孚隆科技为例，其开发的PEEK改性材料已商业化应用于汽车发动机、传动、悬挂/转向、刹车、燃油、HAVC等六大系统的50多个部件。

    近期，常州瑞璐塑业在PEEK保持架注塑成型技术上取得突破，为高性能精密轴承的规模化生产开辟了新路径。相比传统金属保持架，PEEK保持架具备自润滑、耐腐蚀、轻量化等优势，适配高端装备对精密轴承的严苛要求。

    三、应用场景全面开花

    1. 商业航天：轻量化的刚性需求

    商业航天的蓬勃发展对材料提出了严苛的轻量化与耐温要求。PEEK凭借优异的综合性能，已应用于飞机轮毂罩、整流罩、座椅骨架、环境控制系统叶轮、机翼固定件等零部件；在卫星和航天器上，则用于制造结构支架和热防护部件。相比传统铝合金部件，PEEK制件可实现30%-50%的减重，同时降低了加工成本和装配复杂度。

    2. 人形机器人：关节部件的理想材料

    人形机器人的关节和传动系统对材料的耐磨性、耐疲劳性和轻量化有极高要求。PEEK作为关键结构材料，已在国内多家头部机器人企业的研发管线中占据重要位置。金田股份披露，其PEEK材料产品已与国内多家头部企业开展研发合作，为低空经济载重飞行市场提供高压驱动稳定性技术方案。

    3. 医疗器械：老龄化驱动的刚需市场

    全球老龄化趋势推动骨科医疗耗材需求持续增长。PEEK凭借优异的生物相容性、X射线透过性和力学性能匹配度（弹性模量接近人体骨骼），已成为脊柱融合器、牙科种植基台、人工关节等高端医疗耗材的首选材料。这一领域的稳定增长为PEEK市场提供了坚实的底部支撑。

    4. 汽车与工业：从替代到创新

    在汽车领域，PEEK已成功替代不锈钢、钛等金属，用于制造发动机内罩、轴承、密封件和刹车片。新能源汽车的电机绝缘部件、电池组件等新兴需求也为PEEK打开了增量空间。在石油化工领域，PEEK被用于井下电子连接器、空压机气阀阀片、超低温阀座和密封圈等关键部件。

    四、市场前景与选型建议

    据行业分析，全球PEEK市场规模正以每年约8%-10%的复合增速扩张，预计到2030年市场规模将突破百亿元人民币。商业航天、人形机器人、新能源汽车三大新兴赛道的叠加，有望推动PEEK需求加速释放。

    对于采购和研发人员，以下选型要点值得关注：

    • 纯树脂 vs. 改性料：结构件优先选碳纤维或玻璃纤维增强PEEK；耐磨场景选PTFE/石墨填充PEEK；绝缘场景选纯树脂PEEK
    • 国产 vs. 进口：对于常规牌号，国产PEEK性价比优势明显；对于航空级、医疗级等高可靠性要求场景，建议优先选用Victrex、Solvay等国际品牌并通过完整验证
    • 加工方式：注塑成型适合批量化的中小型精密部件；机加工适合少量多样、高精度要求的结构件
    • 成本控制：PEEK单价较高（约800-1500元/kg），建议在设计阶段就充分利用其”以塑代金”的减重和集成化优势，从系统成本角度评估综合效益

    五、结语

    PEEK材料正站在产业爆发的临界点上。商业航天的”太空经济”红利、人形机器人的产业化浪潮、医疗器械的刚性需求——三大驱动力叠加，将PEEK从”小众特种材料”推向”万亿级通用平台材料”的历史机遇期。对于产业链上的企业而言，提前布局PEEK的技术储备和供应链能力，将在这轮材料革命中抢占先机。
