Rubber Material Types for Rubber Seals, Rubber Gaskets and O rings
Materials Technologists are constantly developing new seal materials to meet the increasing demands of today’s engineering applications.
IIR
Resistant to the same fluid types as EPDM , the distinctive properties of IIR rubber materials are very low gas and moisture permeability, excellent insulating properties, good ozone and weathering resistance, and resistance to a great many organic and inorganic media. IIR elastomer materials can be polymerised with various halogens (e.g. Chlorine / Bromine) to improve resistance to certain chemical media, but at the expense of electrical insulation and moisture resistance. They can be used from –40 to +120°C typically, and are mostly used in the production of tyre inner tubes, seals and rubber gaskets, vacuum seals and membranes, and pharmaceutical goods.
