ENHANCING AIR-BARRIER PERFORMANCE

Tires

The inner liner is an essential component of tubeless tires whose demand continues to rise. Using a halobutyl rubber-based inner liner helps the tire to maintain proper inflation pressure in order to provide lower rolling resistance and fuel economy compared to conditions where it is under inflated. Furthermore, the tire needs the correct pressure to ensure that the tire performs well and operates under safe conditions. The only vehicle safety component that actually touches the road is the tire, and the halobutyl inner liner ensures that the tire operates as designed at the proper inflation pressure.

ARLANXEO brominated and chlorinated X_Butyl® polymers are well-suited for the production of a highly effective inner liner layer.

While ARLANXEO's butyl rubber products find their primary applications in the tire industry, their versatile properties also make them attractive for a wider spectrum of technical rubber applications such as medical stoppers, adhesives and sealants, chewing gum, hoses, seals and membranes.

Medical stoppers and plungers

ARLANXEO X_Butyl® bromobutyl and chlorobutyl grades are used in many medical and pharmaceutical applications due to its low permeability, polymer purity, clean cure systems and good ageing characteristics. The healthcare industry must comply with stringent requirements for the protection of sterile pharmaceutical products against external contamination during storage and use. As such, halobutyl rubber is commonly used for stoppers used in infusion containers, injection vials, and blood collection tubes as well as plungers in pre-filled syringes.

Chewing gum

ARLANXEO X_Butyl® RB 101-3 is a specialty product manufactured for the chewing gum industry. In particular, regular butyl rubber is used in the gum base, which is an important starting point for a wide variety of different finished gum products. Butyl’s trademark stability and resistance to ageing helps the gum retain its soft texture during storage.

Other non-tire applications

Ageing resistance and low permeability also makes butyl rubber ideal for a variety of adhesive and sealing applications. Our butyl products are used in adhesive formulations for transparent tapes, hot melt pressure sensitive adhesives, mastic for pipe wrap tapes, as well as flooring and roofing adhesives.
