FAQ

PEEK Material — Common Questions

Answers to the most frequently asked questions about PEEK properties, processing, and industrial applications.

What makes PEEK suitable for extreme industrial environments? +
PEEK combines a continuous service temperature of 250°C, exceptional chemical resistance to most acids, bases, and hydrocarbons, and a tensile strength of up to 100 MPa unfilled — making it one of the few thermoplastics that can directly replace metals in demanding environments. Its semi-crystalline structure also provides excellent fatigue resistance under cyclic loading, critical in aerospace brackets, semiconductor wafer carriers, and medical implants.

Read: PEEK Material for Industrial Applications
What are the key parameters for injection molding PEEK correctly? +
PEEK requires precise processing conditions due to its high melting point of 343°C. Barrel temperatures should be set between 360–400°C, mold temperature maintained at 160–180°C to ensure proper crystallisation, and injection speed kept moderate to avoid shear degradation. Pre-drying at 150°C for 3–4 hours is mandatory to prevent hydrolysis. Post-mold annealing at 200°C for 2–4 hours is strongly recommended to relieve residual stress and achieve stable dimensional tolerances — especially critical for tight-tolerance components.

Read: PEEK Injection Molding Processing Window & Annealing Guidelines
How can warpage and deformation be minimized in PEEK parts? +
Warpage in PEEK components is primarily caused by rapid or uneven cooling, inadequate mold temperature control, and residual stress from improper gate placement. Key practices include maintaining mold temperatures between 160–180°C, using slow and uniform cooling cycles, annealing finished parts at 200°C for 2–4 hours, and optimizing wall thickness uniformity in the part design. For machined semi-finished stock, stress-relief annealing before tight-tolerance operations is also highly recommended.

Read: How to Minimize Warpage and Deformation in PEEK Components
What is the difference between unfilled PEEK and reinforced grades? +
Unfilled PEEK offers the best chemical resistance, optical translucency, and biocompatibility — ideal for medical implants, chemical-contact components, and food-grade applications. Reinforced grades trade some chemical resistance for significant performance gains: GF30% increases stiffness and reduces creep by ~50%; CF30% maximises rigidity and adds electrical conductivity for ESD applications; PTFE-lubricated grades dramatically lower friction for dynamic bearing and seal applications. The right grade depends on the combination of mechanical load, chemical exposure, and regulatory requirements in your application.
Is PEEK safe for medical implants and food contact applications? +
Yes — implant-grade PEEK is certified to ISO 10993 and USP Class VI, confirming biocompatibility for long-term body contact. Its radiolucency and modulus close to cortical bone make it the preferred material for spinal fusion cages, dental abutments, and trauma fixation devices. For food contact, unfilled natural PEEK complies with EU 10/2011 and FDA regulations. Note that reinforced grades (GF, CF) are generally not certified for implant or food-contact use — always specify the correct grade for your regulatory requirements.
