Polypropylene Copolymer
Polypropylene Copolymer Overview
What is the Material: Polypropylene Copolymer is a semi-crystalline material.
Key Material Features: This material is beneficial in applications requiring chemical resistance, low moisture absorption, thermal and electrical properties, and low density.
Other Considerations: This material can be used in applications requiring lower temperatures than polypropylene homopolymer.
