Uses for Chlorobutyl Rubber (CIIR)
- Chlorobutyl Rubber (CIIR) is one of the most commonly used rubber materials in the automotive industry. It is employed in the production of automotive components such as tires, rubber seals, and rubber hoses. These components require properties including oil resistance, heat resistance, cold resistance, and aging resistance, all of which chlorobutyl rubber can fulfill.
- Chlorobutyl Rubber (CIIR) finds extensive application in the construction industry due to its oxidation resistance, weather resistance, and cold resistance. It is used to produce building materials like sealing strips and waterproof panels, as well as seismic bearings for building steel structures.
- It is also employed in the cable industry for manufacturing cable jackets and insulation layers. Due to its excellent heat resistance, electrical properties, and corrosion resistance, CIIR effectively protects cables and electrical equipment from damage.
Warranty Period for Chlorobutyl Rubber (CIIR)
Store in a well-ventilated, dry environment in a sealed container. Shelf life: 2 years.
