PEEK is a high performance engineering thermoplastic that offers chemical and water resistance similar to PPS, but can operate at higher temperatures. PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-0 flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.
Advantages:
- Excellent chemical resistance - Very low moisture absorption - Inherently good wear and abrasion resistance - Unaffected by continuous exposure to hot water or steam - High temperature resistant, can withstand 250°C
Key Features:
- Strong and stiff plastic - Outstanding chemical resistance - Good mechanical properties at elevated temperatures - Resistant to hot water and steam - Bearing grade PEEK has excellent wear characteristics - UL 94 V-0 flammability rating (0.059" thickness) - Very low smoke and toxic gas emissions when exposed to flame
Applications:
- Semiconductor machinery components - Aerospace parts - Seals - Pump and valve components - Bearings and bushings (bearing grade PEEK) - Electrical components - Medical instrument parts - Food processing machinery components
