PEEK Injection Moulding
PEEK parts offer high strength, stiffness, and chemical resistance
PEEK, or poly ether ketone, is a high performance thermoplastic with excellent strength and ductility. It's also FDA compliant for food contact and can be sterilised for medical applications.
- Good strength and stiffness
- High ductility
- Chemically resistant
- Food safe
