Description: Style AG40NEMG is a 40 durometer medium grade neoprene gasketing material designed for use in a wide variety of applications which require a higher percentage of neoprene than our commercial grade (AG40NECG). Known by the chemical name chloroprene, Style AG40NEMG provides good weathering and ozone resistance for your gasketing applications. 40 durometer mid-grade neoprene is made from Neoprene (51%) and a blend of other elastomers and has a service temperature of -30°F to +200°F. 40 durometer medium grade neoprene also offers moderate resistance to oil and gasoline. Style AG40NEMG is formulated to meet the ASTM D2000 M1BC 403 specification.
Atlantic Gasket’s medium grade neoprene is available in a wide range of durometers, ranging from as soft as 30 Durometer (AG30NEMG) to as hard as 80 Durometer (AG80NEMG) with standard durometers in between. Style AG40NEMG 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. 40 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. Additional widths are available upon request. Atlantic Gasket has the ability to fabricate 40 durometer medium grade neoprene by die-cutting or waterjet cutting to meet your design and production requirements.
