Chlorinated Butyl Rubber (CIIR) Price | Factory Direct Manufacturer & Supplier

Core Performance Advantages of Chlorinated Butyl RubberSuperior gas impermeability: CIIR has an air permeability only about 1/8 that of natural rubber, making it the core material for tire inner liners and sealing gaskets. It maintains long-term sealing performance and reduces operational loss of end products.Fast curing & co-vulcanization compatibility: The chlorination modification gives CIIR a faster vulcanization rate and a wider curing window. It can be co-vulcanized with natural rubber, butadiene rubber and other general-purpose rubbers, adapting to mainstream rubber processing technologies and improving production efficiency.Excellent weather and ozone resistance: It maintains stable physical properties under outdoor exposure, ozone environments and wide temperature ranges. Its anti-aging service life is far longer than ordinary synthetic rubber, suitable for long-term outdoor industrial seals and rubber hoses.Good chemical and heat resistance: It has strong erosion resistance to most acid-base media, vegetable oils and mineral oils, and can work stably for a long time below 100°C, meeting the special working condition requirements of chemical and pharmaceutical industries.
