Typical Properties of 30 Durometer Medium Grade Neoprene

Description: Style 30 durometer medium grade neoprene gasket material designed for use in a wide variety of applications which require a higher percentage of neoprene. Known by the chemical name chloroprene, 30 durometer medium grade neoprene provides good weathering and ozone resistance for your gasket applications. 30 durometer medium grade neoprene is made from Neoprene (51%) and a blend of other elastomers and has a service temperature of -30°F to +200°F. 30 durometer medium grade neoprene offers moderate resistance to oil and gasoline. 30 durometer medium grade neoprene is formulated to meet the ASTM D2000 M1BC 303 specification.

M&P Sealing’s medium grade neoprene is available in a wide range of durometers, ranging from as soft as 30 Durometer to as hard as 80 Durometer with standard durometers in between. 30 durometer medium grade neoprene is available in the color black and can be manufactured in a wide range of standard thicknesses, ranging from as thin a 1/32″ to as thick as 1/4″, with custom thicknesses available upon request. 30 durometer medium grade neoprene has a smooth finish and can be converted into rolls ranging from as narrow as 1/4 wide up to 48″ in width. Custom widths are available upon request. M&P Sealing has the ability to fabricate 30 durometer medium grade neoprene by die-cutting or waterjet cutting to meet your exact requirements.
