Polypropylene Homopolymer
Polypropylene Homopolymer Overview
What is the Material: Polypropylene Homopolymer 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 higher temperatures than polypropylene copolymer.
