Engineering Resins FAQ

Expert answers to common questions about high-performance engineering resins

For Engineers

When should I choose PEEK over other engineering resins?

PEEK is chosen for the most demanding applications: continuous use to 250°C, FDA implantable (Class VI), excellent chemical resistance, and gamma sterilizable. Use PEEK when no other material meets requirements. POM, PPS, or PEI may be more cost-effective for less extreme requirements.

What are the processing challenges with PEEK?

PEEK requires high processing temperatures (360-400°C), specialized equipment with precision temperature control, and rigorous drying (150°C for 4-12 hours). It has high melt viscosity requiring high injection pressures. We have dedicated PEEK-capable equipment and extensive experience.

How does POM compare to nylon for precision parts?

POM has lower moisture absorption (0.2% vs 3% for nylon), better dimensional stability, lower friction, and higher stiffness. Nylon has better impact strength and wear resistance when lubricated. POM is preferred for precision gears, bearings, and fasteners requiring tight tolerances.

What glass transition temperatures should I consider?

Key Tg values: POM ( -60°C, crystalline), PPS (85°C), PEI (217°C), PEEK (143°C). For continuous use above Tg, consider crystalline materials (PPS, PEEK) with high melting points. Amorphous materials (PEI) soften above Tg but have better transparency and easier processing.

For Procurement

What engineering resin brands do you offer?

Authorized distributors for: Solvay (KetaSpire PEEK, Ryton PPS), SABIC (Ultem PEI, Noryl), BASF (Ultramid, Ultraform), DuPont (Delrin, Zytel), and Victrex (PEEK). All materials with full traceability and lot-specific data sheets.

What are lead times for engineering resins?

Prototype molds: 10-20 days (specialized tooling). Production molds: 5-8 weeks. Production parts: 3-4 weeks. PEEK and specialty materials require longer lead times due to specialized drying and processing. Rush services available for qualified projects.

Do you offer custom engineering resin compounds?

Yes, we work with material suppliers to develop custom compounds including glass-filled, carbon-filled, PTFE-filled, and color-matched grades. We can also incorporate additives for specific properties like conductivity or flame retardancy.

What's your quality guarantee for engineering resins?

Parts meet specs or we replace free. 99.5% first-pass yield with full material certification, SPC, and CMM verification. Full traceability from raw material to finished part. PPAP and PFMEA support for automotive and aerospace.
