Butyl Rubber

Butyl Rubber

Butyl rubber is a product, which is maintaned after copolymerization of isobutylene and isoprene. It has milk-white color. Its key features are high impermeability, resistance to heat and ozone and energy absorption.

BUTYL RUBBER (BK 1675) TECHNICAL DATA SHEET

Applications: Tire industry, inner tubes, curing bladders, rubber-fabric materials, lining shafts, chemical equipments, heat resistant conveyor belts and hoses, seals for use in aggresive environments and high temperatures, cable industry for wire and cables, sporting equipment (bladders in sporting balls, damp proofing, roof repair, roof membranes (especially around the edges), medical stoppers (used for sealing medicine vials and bottles), food industry, conveyor belts, hoses, chewing gum

Intended use: Provides consistent inflation pressure, reduction in tire Rolling resistance due to the better inflation pressure retention, leading to the potential for less fuel consumption, longer tire life and more-even wear performance, longer inner tube life due to better heat stability, enhanced tire durability, a tough, airtight inner compartment in sporting equipments.
