Butyl Rubber Rolls

Butyl Rubber Rolls is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for Isobutylene Isoprene Rubber. A synthetic rubber, or elastomer, butyl rubber is impermeable to air and used in many applications requiring an airtight rubber. The first major application of butyl rubber was tire inner tubes and is used in lining tubeless tires. Butyl rubber is a good general purpose rubber for low gas and moisture permeability, resistance to ozone, weather, abrasion, tear, flexing, heat aging, and chemical attack. Butyl rubber also has good electrical insulation performance and high shock absorption characteristics. These properties have made butyl rubber the polymer choice in a variety of applications. Hypalon® (the former DuPont brand name for chlorosulfonated polyethylene or CSM) is an ozone resistant synthetic rubber that is resistant to oil, weather exposure, color change, heat, flame and flex fatigue. Hypalon® is a synthetic rubber used to waterproof a fabric substrate for a variety of outdoor end use applications. As an industrial cover or jacketing material it provides excellent abrasion and flex fatigue resistance. It’s a great choice for dock seals and other outdoor applications. CSM’s can be compounded to provide excellent flame and oil resistance as well as resistance to weather, ozone, and oxidizing chemicals.
