Murylon® A GF

Chemical Family: Polyamides

Murylon® A GF, the properties of this material surpass the already impressive characteristics of Murylon® A. This is possible thanks to admixed glass fibers. The result: A clear improvement in cold flow behavior and dimensional stability. This enables higher static pressure loads to be endured. Production based on PA66.
