Product Description

Polypropylene (PP) | Properties, Applications & Price

What is Polypropylene (PP)?

Polypropylene, abbreviated as PP, is a semi-crystalline thermoplastic from the polyolefin family. It shares similarities with polyethylene (PE) but offers higher thermal and mechanical properties. Although it’s more expensive than PE—typically twice the price—its superior resistance to chemicals and heat makes it a preferred choice for demanding applications.

At Shemsh Plastic Azadi, PP is available in a variety of thicknesses and dimensions in both sheet and rod form.
