Low Mooney grade. White to light amber bales. Butyl rubber is a copolymer of isobutylene and a small amount of isoprene, providing for a highly saturated backbone. The primary properties of butyl rubber are excellent air-barrier performance, good flex fatigue and vibration damping. From inner tubes to curing bladders, butyl properties are valued across a range of rubber products. Benefits: Low permeability to air, gases and moisture, Vibration damping, Low glass transition temperature, Low modulus elastomer, Low compression set, Resistance to aging and to weathering from atmospheric exposure, Wide vulcanization versatility, Fast cure rates, Processing safety: no nitrosamines or nitrosamines precursors, Broad range of durometer and tensile strength properties, Low filler content for specific gravity, cost-effective compounding.
