DD peek MED
The polymer steel
Blank made of polyetheretherketone
Medical PEEK
DD peek MED are biocompatible milling blanks based on the high-performance plastic polyetheretherketone.
Advantages:
- Bonding to cold polymers (PMMA) possible with bonder
- Extremely resilient
- Several colors for different applications
