PA 620-MF


PA 620-MF is a mineral fiber filled nylon 12 easy to process, performing and heavier weight filled material.

Fibers have been optimized to produce a smooth surface finish without sacrificing feature detail for mechanical properties.

PA 620-MF is an excellent choice for rugged industrial or tooling applications with high tensile modulus values and HDT of ~ 177°C, applications for aerospace and motor sports and enclosures. It is ideal for low to mid production parts requiring stiffness and durability at elevated temperatures.

Drop in replacement for other commercially available fiber filled materials with an increase in recyclability.
