Halobutyl rubber is the raw material which tire producers use to make gas-tight inner liners in tubeless tires for cars, trucks, buses and bicycles. One of the most important properties of this elastomer is its high impermeability to moisture and gases, such as air. In this field, LANXESS products help to protect the steel cord from moisture and maintain the tire pressure at a constant level for longer, thereby saving fuel. In addition, halobutyl rubbers have proven their impermeability to gas and resistance to chemicals in vehicle air conditioning systems and tank linings. The most important market for halobutyl rubbers is the tire industry.
The LANXESS Butyl Rubber business unit handles the development, manufacturing and marketing of butyl rubber grades.
Butyl rubber is a co-polymerizate of 95-99 mol-percent isobutene and 1-5 mol percent isoprene. Approximately 85 percent of globally produced butyl rubbers go into the manufacture of car tires.
