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 PP has a high Melt Flow Index (MFI=30) and is fairly easy to inject.
              This is a good all-around general purpose material.
