  • Product Review: VESTAKEEP 5000G PEEK Granules

    Overview

    The VESTAKEEP 5000G from Evonik is an unfilled, medium-viscosity PEEK granule designed for injection molding and extrusion. As demand for metal-replacement polymers surges across aerospace, medical, and semiconductor sectors, this Grade-5000 series compound has become one of the most specified unfilled PEEK resins on the market.

    Key Specifications

    • Density: 1.30 g/cm3
    • Tensile Strength (23 C): 100 MPa
    • Tensile Modulus: 3,800 MPa
    • Elongation at Break: 25%
    • Heat Deflection Temp (HDT/A): 165 C
    • Melting Point: 340 C
    • Continuous Service Temp: 250 C
    • LOI: 35%
    • UL 94: V-0 (0.8 mm)
    • MFI (380 C / 5 kg): 5-8 g/10 min

    Processing and Molding Performance

    The 5000G medium viscosity strikes a pragmatic balance: it fills complex mold geometries more reliably than the high-viscosity 4000 series, yet retains enough melt strength for extrusion of rods, tubes, and monofilaments. Recommended barrel temperatures sit at 370-400 C with mold temperatures of 170-200 C. We observed excellent dimensional stability in thin-wall parts down to 0.5 mm.

    One notable advantage: VESTAKEEP 5000G exhibits minimal plate-out on screw surfaces over extended runs, reducing downtime for cleaning. In a 72-hour continuous molding test, torque drift stayed under 3%, commendable for an unfilled PEEK.

    Mechanical and Thermal Evaluation

    Tensile strength at 100 MPa places the 5000G at the upper end of the unfilled PEEK envelope. Its retention ratio at 250 C is roughly 45% of room-temperature values, competitive with Victrex 450G and Solvay KetaSpire KT-820. Creep resistance under a 20 MPa load at 200 C showed less than 0.8% strain after 1,000 hours.

    Chemically, the resin is virtually inert to organic solvents, automotive fluids, and most acids below 200 C. Concentrated sulfuric acid at elevated temperatures remains the Achilles heel, as with all PEEK grades.

    Application Scenarios

    • Aerospace – Bracket and bushing replacements for aluminum; weight savings of 40-60% with comparable fatigue life under 150 C service.
    • Medical Implants – The unfilled nature makes biocompatibility certification (ISO 10993) more straightforward; ideal for spinal cages and dental abutment blanks.
    • Semiconductor – Wafer carrier components and CMP retaining rings where outgassing must stay below 0.1% TML; VESTAKEEP 5000G passes SEMI E90 comfortably.
    • Oil and Gas – Seal and backup-ring elements in downhole tools operating at 200+ C with H2S exposure.

    Selection Advice

    Choose VESTAKEEP 5000G when: you need a reliable, unfilled PEEK with balanced flow and mechanical properties for complex injection-molded parts, especially if regulatory traceability and consistent lot-to-lot performance are priorities.

    Consider alternatives when:

    • Highest creep resistance required: carbon-fiber-filled VESTAKEEP 1015CF or Victrex 150CA30.
    • Cost is the primary driver: explore PEKK or PPSU families for 20-40% material savings at reduced temperature capability.
    • Extreme wear resistance needed: PEEK with PTFE/graphite internal lubricants.

    Verdict

    The VESTAKEEP 5000G is a best-in-class unfilled PEEK for precision molding. It is a focused, well-characterized resin that does the fundamentals exceptionally well: consistent processability, strong mechanical retention at elevated temperatures, and a clean regulatory pedigree. For engineers who cannot afford lot-to-lot surprises in mission-critical polymer components, this is the benchmark unfilled PEEK to specify.

    Rating: 9 / 10

    • Order volume: Volume discounts are substantial. A 100 kg order may cost 20–30% more per kg than a 2,000 kg order. Many manufacturers offer tiered pricing at 500 kg, 1,000 kg, and 5,000 kg thresholds.
    • Grade complexity: Specialty grades (medical-grade, aerospace-grade, custom compounds) carry 15–40% premiums over standard unfilled PEEK.
    • Form factor: Granules are cheapest per kg. Semi-finished products (rods, sheets, tubes) add machining costs. Finished components add labor and precision costs.
    • Certification requirements: USP Class VI, ISO 13485, FDA-compliant, and AS9100 certifications add to the price but are essential for regulated industries.

    PEEK vs. Alternative High-Performance Polymers

    When evaluating materials for demanding applications, buyers often compare PEEK with alternatives:

    Property PEEK PEI (Ultem) PPS PI (Polyimide)
    Max Service Temp 250°C 170°C 220°C 260°C
    Tensile Strength 90–100 MPa 105 MPa 75 MPa 85 MPa

  • PEEK vs PI: Engineering Polymer Selection Guide

    Introduction

    When selecting high-performance polymers for demanding engineering applications, PEEK and polyimide (PI) are two leading candidates. Both offer exceptional thermal and chemical resistance, but key differences can make or break your design.

    What are the core differences between PEEK and PI?

    PEEK (polyetheretherketone) is a semi-crystalline thermoplastic known for excellent mechanical strength and chemical resistance. PI (polyimide) is an amorphous thermosetting polymer with superior thermal stability. PEEK melts at ~343°C and maintains strength up to 260°C continuously, while PI can withstand 300-400°C with minimal degradation.

    Which material performs better in high-temperature environments?

    For continuous service above 280°C, PI is the clear winner. PEEK begins to lose mechanical properties around 260°C, though short-term exposure to 315°C is acceptable. PI maintains its integrity at 300°C+ due to strong aromatic imide bonds. If your application involves sustained heat above 260°C, choose PI.

    How do they compare in chemical resistance?

    PEEK offers outstanding resistance to organics, acids, and bases. It survives prolonged exposure to steam, autoclaving, and most solvents. PI, while resistant to many chemicals, is vulnerable to strong acids and bases. For chemical processing equipment, PEEK is typically the better choice.

    Which is easier to manufacture?

    PEEK wins on manufacturability. As a thermoplastic, it molds, extrudes, and machines easily with standard equipment. PI requires heat-treated curing and careful processing to avoid voids. For complex geometries, PEEK reduces production costs significantly.

    What about wear and friction?

    Both perform well in tribological applications. PEEK composites with carbon fiber or PTFE achieve wear rates below 10⁻⁶ mm³/Nm. PI exhibits lower friction coefficients but higher wear. For articulating surfaces, PEEK formulations are preferred.

    Practical Selection Guidelines

    • Choose PEEK when: continuous service under 250°C, chemical exposure, steam sterilization, complex geometry, FDA compliance needed
    • Choose PI when: sustained temperatures above 280°C, aerospace applications, minimal outgassing required, radiation exposure

    Conclusion

    PEEK offers easier processing and broader chemical resistance. PI excels in extreme heat. Evaluate your specific thermal, chemical, and mechanical requirements to make the optimal choice for your application.
