Mineral Filled Polypropylene Plastic Extrusions

Material Update:
The global availability of Mineral Filled Polypropylene is currently limited due to external forces which damaged key production resources in the supply chain. Because we work with multiple suppliers as a normal business practice, we have numerous options that can be a great (or sometimes superior) substitute. We’d be happy to walk you through the possibilities!

Mineral Filled Polypropylene Plastic Extrusions


Mineral filled polypropylene provides high mechanical stiffness, thermal stability, good low temperature properties and good dimensional stability over a wide temperature range. Available as a natural colored, colorable, UV stabilized compound.
