Typical Properties of 70 Durometer High-Grade Neoprene
Description: 70 durometer high-grade neoprene designed for use in gasket applications that require a solid neoprene material with high tensile strength. With a service temperature of -30°F to +220°F, 70 durometer high-grade neoprene provides resilience in both cold and hot temperatures. 70 durometer high-grade neoprene offers good resistance to oil and petroleum base solvents and excellent resistance to dilute acids. Known by the chemical name chloroprene, 70 durometer high-grade neoprene is made from 100% neoprene and is suited for rigorous applications while giving users a gasket material with excellent weathering and ozone resistance. 70 durometer high-grade neoprene is formulated to meet the ASTM D2000 M1BC 710 specification.
M&P Sealing’s high-grade neoprene is available in a wide range of durometers, ranging from as soft as 30 Durometer to as hard as 90 Durometer with standard durometers in between. 70 durometer high-grade neoprene is available in the color black and can be manufactured in a wide range of standard thicknesses, ranging from as thin a 1/64″ to as thick as 1/4″, with custom thicknesses available upon request. 70 durometer high-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. M&P Sealing can die-cut, or waterjet cut 70 durometer high-grade neoprene to meet your exact requirements.
