NC711G

Product Overview
AMORIM NC711G is a roll-type sealing product composed of a composite of chloroprene rubber and natural cork. While retaining the unique compressive resilience of cork, the specialized rubber matrix endows the material with superior oil and chemical resistance. It is suitable for industrial sealing applications demanding high tolerance to petroleum products.
