Material Update:
The global availability of Mineral Filled Polypropylene is currently limited due to damaged 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’re happy to walk you through the possibilities! Call us today to discuss your needs & let us find a material solution for you.
Description:
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.
