Description: Style AG50BTL is a 50 durometer butyl gasketing material that is impermeable to air and is used in many applications that require a solid mechanical airtight rubber. 50 durometer butyl presents users with a service temperature of -40°F to +180°F. Also known as Isobutylene-isoprene, Style AG50BTL is formulated to meet the ASTM D2000 M1AA 507 specification.
Atlantic Gasket’s solid rubber butyl material is available in a wide range of durometers, ranging from as soft as 40 Durometer (AG40BTL) to as hard as 70 Durometer (AG70BTL) with standard durometers in between. Style AG50BTL 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. 50 durometer butyl 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. Send in a drawing, and let Atlantic Gasket die-cut or waterjet 50 durometer butyl to meet both prototype and production requirements.
