RHENOGRAN® P91-40/EPDM

Product Description

Rhenogran® P91 40/EPDM is a masterbatch of aramid chopped fiber pulp finely dispersed in an EPDM binder. This advanced reinforcement improves dimensional stability, green strength, and a broad range of physical properties—including modulus, hardness, abrasion and tear resistance, compression resistance, flexural strength, penetration resistance, shrinkage, and creep resistance—without affecting cure rate. 

The polymer-bound, predispersed form enables excellent dispersion and easy processing, making it practical to achieve full reinforcement benefits without fiber agglomeration. Fiber orientation in mixing enhances composite performance.

THESE SPECIAL FEATURES MAKE THIS PRODUCT SO SUCCESSFUL
