IIR

Butyl rubber (isobutylene, isoprene rubber, IIR) is produced by several suppliers in different types that differ in their isoprene content. Isoprene is added for vulcanization.

Butyl has a low gas permeability to air, water vapor and other gases. It also has good electrical insulation properties and good resistance to oxygen, ozone and chemicals.

Temperature range : -40 to +130°C

Applications : Where low gas permeability and good heat and ageing resistance are required, such as in car and bicycle tubes, inner layers of tubeless tires, acid protection linings, seals and membranes, etc. IIR also has other applications in the cable industry and for electrical insulation.

Disposal

According to the “Regulation on the European Waste Catalogue (AVV)”, the waste product from IIR can be classified according to Chapter 7 “Wastes from organic chemical processes” and the waste code 07 02 99. This waste code stands for waste classified as non-hazardous.

They can therefore be disposed of in normal household quantities with normal household waste. Please use the container provided by your public waste disposal authority for residual waste as the appropriate disposal container.
