- Product Background
- Butyl rubber is a synthetic polymer, a copolymer of isobutylene with isoprene. It’s abbreviated as IIR (Isobutylene-Isoprene rubber).
- The key advantages butyl rubber offers is superlative air-barrier performance with superior flex properties. IIR is extensively used to manufacture tire’s Inner Tube. It offers matchless ozone & weather resistance along with heat stability.
- Key Benefits
- Low air permeability
- Good weather & Ozone resistance
- Good heat stability
- Good dampening properties
