Butyl rubber is an isobutylene copolymer with a small amount of isoprene. Highly resistant to oxygen, ozone and solutions of acids, alkalis and salt. It is nonreactive with oxidizing agents such as lime chloride, potassiom permanganate and dichromate. Elasticity of butyl rubber is increased by long-term heating in the air up to +100°C. At the temperature from +180 up to + 200°C , it can be extruded. Butyl rubber is widely used in construction, sealing, waterproof coatings, mastics, pastes , glues.

Among the speciality elastomers polychloroprene is one of the most important with an annual consumption of nearly 300,000 tons worldwide. CR has an outstanding position due to its favourable combination of technical properties. It is used in different technical areas, mainly in the rubber industry(ca. 61%), and is also important as a raw material for adhesives (both solvent based and water based, ca.33%) and has different latex applications (ca.6%) such as gloves & other dipped articles.

EPDM rubber (ethylene propylene diene monomer (M-class) rubber), a type of synthetic rubber, is an elastomer characterized by a wide range of applications. The ethylene content is around 45% to 85%. The chemical exhibits satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, adn alkalis and exhibits unsatisfactory compatibilty with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents, and concentrated acids.

Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene. These materials have good abrasion resistance and good aging stability when protected by additives. About 50% of car tires are made from various types of SBR. The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. It is a commodity material which completes with natural rubber.

Silicone rubber is an elastomer composed of silicone - itself a polymer - containing silicon together with carbon, hydrogen, and oxygen. They are widely used in industry in multiple formulations. It is generally non-reactive, stable, and resistant to extreme environments and temperatures from -55°C to +300°C while still maintaining its useful properties and its ease of manufacturing and shaping, silicone rubber can be found in a wide variety of products.
Chlorosulfonate polyethylene (CSM) is widely known as Hypalon®.1 It can be considered a superior type of chloroprene, having better heat and chemical resistance. CSM grades usually contain 20 - 45 percent chlorine which provides excellent resistance to ozone, UV, weathering and chemicals. This includes oxidizing agents, hot water(when cured) and corrosive chemicals. It also has good resistance to dry heat up to 150°C, low flammability, low gas permeability, and good electrical properties.
SBS (Styrene Butadiene Styrene) is a thermoplastic elastomer made with two monomers, which are styrene and butadiene, and shows the properties of plastic and rubber at the same time. Due to these properties, it is widely used in a variety of areas including plastic modifying agent, asphalt modifying agent and adhesives.
Ethylene-vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. The weight percent vinyl acetate usually varies from 10 to 40%, with the remainder being ethylene. EVA is a elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. It has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications.
Nitrile butadiene rubber (NBR) is a family of unsaturated copolymers of 2-propenenitrile and various butadiene monomers. Although its physical and chemical properties vary depending on the polymer's composition of nitrile, this form of synthetic rubber is unusual in being generally resistant to oil, fuel and other chemicals. It is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets and self-sealing fuel tanks, since ordinary rubbers cannot be used.
