PEEK
- Chemical Family
- Polyether Ether Ketone (PEEK)
PEEK sheet (polyether ether ketone) is an extremely tough, wear resistant plastic with excellent resistance to high temperatures and energy radiation. It is very dimensionally stable plastic and has a high mechanical bearing strength. PEEK plastic sheet also offers excellent chemical resistance and a high resistance to hydrolysis, even against super-heated steam.It is also electrically insulating and has good sliding properties. It is easy to machine and is FDA approved for use with food.
