Polypropylene (PP) is a common thermoplastic resin typically used for injection molding applications. It offers a good balance of properties and cost, uncommon to most other thermoplastics. Polypropylene provides outstanding physical, chemical, mechanical, thermal, and electrical properties not found in any other thermoplastic.

This Brown Polypropylene has a high melt-flow value and is very easy to inject.

The mold will need slight pre-heating for best results. This is a good all-around general purpose material.
