Fullchance Butyl Rubber is a copolymer or isobutylene and a small percentage of isoprene and has a very low permeability to air and other gases. Butyl rubber has excellent resistance to ozone, oxidation and sunlight.
Physical character:
made by drum-type vulcanizing press(ROTOCURE) or vulcanizing press with high quality butyl rubber(IIS, one of synthetic rubber, brominated butyl or halobutyl butyl). 1-6mm thickness is made by drum-type vulcanizing press(ROTOCURE) with shiny surface, 7-80mm thickness is made by vulcanizing press for get higher thick thickness. It is with middling hardness and high tensile strength, excellent performance of ozone resistant, oil resistant, vacuum resistant, acid & alkali resistant, chemic cautery resistant, providing unique properties such as low air permeability, high heat resistance, excellent flex cracking resistance, and processability, makes it valuable in tire inner liner applications. It could work in the air, oil, acid or alkali and all kinds of other chemic solution which contains 80% cautery material at the temperature of -20°C - +200°C. Apply to punch all kinds of seals, gaskets at military, spaceflight, chemical industry and other high-tech request.

Application:
Butyl rubber has a very low resilience which makes it ideal for vibration damping and shock absorption application. But offer a moderate resistance to abrasion and compression set. With careful compounding, butyl compound can be made to acquire really good tensile strength. Butyl is resistant to most inorganic products and highly resistant to mineral acids, alkalis and aqueous acids.
Note: Fullchance do no recommend its use in application where resistance to oils and hydrocarbons is required.
***when you enquiry, pls confirm the tensile strength, hardness, color, size and quantity***
