Polypropylene  Polypropylene
Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. Polypropylene is a high corrosion resistant material that has high temperature resistance and tensile strength. Polypropylene possesses excellent resistance to organic solvents and degreasing agents as well as electrolytic attack.

Compared to low or high density polyethylene, polypropylene has a lower impact strength but superior working temperatures and tensile strength. In addition, polypropylene is lightweight, stain resistant and has a low moisture absorption rate.
