This sheet rubber product has a durometer range of 65-75 which is considered a harder and denser rubber sheet. It is a moderately oil and ozone resistant rubber sheet, for use as sealing and in general rubber gasket applications. This rubber sheeting has less elasticity and flexibility than other rubber sheet goods. Hard Neoprene is a good choice for applications which require a resilient and abrasion resistant rubber. Some recommended applications include rubber bumper pads, hanger seals, and industrial rubber surface protection. Color: Black.
