Copolymer POM-C Color Masterbatch
Standard copolymer acetal grade for general precision mechanical parts.
Our POM color masterbatch is formulated for copolymer acetal (POM-C) with excellent thermal and chemical stability. The carrier system avoids depolymerization reactions, ensuring good color development across the full spectrum.
Product Features
- Excellent thermal stability (no depolymerization)
- No formaldehyde odor during processing
- Good chemical stability
- Full color spectrum available
- > 95% mechanical retention
