Polypropylene — PP Glass Filled 20%

Polypropylene, also known as PP, is among the most economical thermoplastic polymer today. However, it has the lowest density among commodity plastics, making it lighter in weight. 
PP can be used as an engineering polymer as it is usually tough and flexible. Adding 20% glass fibres in PP increases its stability, rigidity, and strength. Moreover, it offers a good balance of properties and cost.
