Rubber Gaskets and O Rings are made from a variety of rubber materials.

 IIR rubber materials have low gas and moisture permeability, excellent insulating properties, good ozone and weathering resistance, and resistance to a wide range of organic and inorganic media. They are resistant to the same fluid types as EPDM. IIR elastomer materials can be polymerized with various halogens (e.g., Chlorine/Bromine) to improve chemical resistance, but at the cost of electrical insulation and moisture resistance. They are commonly used in the fabrication of tire inner tubes, seals and gaskets, vacuum seals and membranes, and pharmaceutical items, and can withstand temperatures ranging from -40 to +120°C.

Chlorine is present in the polymer of chlorobutadiene rubbers to limit reactivity to a variety of oxidizing chemicals, as well as oil and flame. CR elastomers also exhibit good resistance to ozone cracking, heat aging, and chemical assault. Vee-belts, coated textiles, cable jackets, tire sidewalls, seals and gaskets in contact with refrigerants, mild chemicals, and atmospheric ozone are just a few of the many applications for CR elastomers.

CSM grades have a chlorine content of 24-43 percent, which provides excellent ozone and weather resistance, sun and ultraviolet light discoloration resistance, high resistance to many oxidizing and corrosive chemicals, good resistance to dry heat up to 150°C, low flammability, and gas permeability, and also good resistance to hot water (when cured with lead oxide). Low-temperature properties are often limited, and the compression set is poor, depending on the chlorine content of the CSM grade employed. Electrical applications, weather-resistant membranes, hoses, and acid-resistant tank linings all benefit from CSM elastomers.
