Typical Properties of 70 Durometer Commercial Grade Neoprene
Description: 70 durometer commercial grade neoprene gasketing material designed for use in a wide variety of applications which require a general purpose solid rubber elastomer. Known by the chemical name chloroprene, 70 durometer commercial grade neoprene provides good weathering and ozone resistance for your gasketing applications. 70 durometer commercial grade neoprene is made from Neoprene (13%) and a blend of other elastomers and has a service temperature of -30°F to +200°F.
M&P Sealing’s commercial grade neoprene is available in a wide range of durometers, ranging from as soft as 40 Durometer to as hard as 80 Durometer with standard durometers in between. 70 durometer commercial 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 1/2″, with custom thicknesses available upon request. 70 durometer commercial 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 capability to die-cut or waterjet cut 70 durometer commercial grade neoprene to meet your prototype and production needs.
