Butyl rubber (IIR) is an isobutylene copolymer with a small amount of isoprene. Butyl rubber is highly resistant to oxygen, ozone, and solutions of acids, alkalis and salt. It is nonreactive with such oxidizing agents as lime chloride, potassium 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. Elastic properties of butyl rubber are maintained up to −55°C.

Butyl rubber is widely used in construction, technical rubber industries for production of anticorrosion, sealing, waterproof coatings, mastics, pastes, glues.

Dear partners,

Hereby we inform you that from the 1st of February 2018 new abbreviation of the trade name for Butyl rubber produced by LLC SIBUR Togliatti will be changed to:

-Butyl rubber IIR-1675;

-Butyl rubber IIR-1675 grade M.


Polybutadiene synthetic is essentially a polymerization product of butadiene in solution. The polymer contains no nitrosamines and substances that may become a source of nitrosamines. Density of all grades of the butadiene rubber is 0.90-0.92 г/см3 (at +25°С). Polybutadiene rubber is rubber which gives the following properties: high wear due to the low coefficient of friction and strength properties, excellent elastic properties and low hysteresis loss, resistance to low temperatures The main field of polybutadiene rubber application is tire industry.


Emulsion Styrene-Butadiene Rubber with oil (SBR) is essentially butadiene-1.3 and styrene or methylstyrene copolymer obtained by emulsification method with the use of resin/fatty soaps. The copolymer is filled with oil HI-AR or TDAE.

SBR is widely used in tire, industrial rubber, cable and footwear industries. Wide use of SBR is explained by availability of the monomers and high technical properties of the rubbers based on them.


Isoprene rubber is a synthetic rubber produced using complex catalysts of stereospecific polymerization in solvents.

Isoprene rubber is highly resistant to fractures and abrasion. It has electroinsulating resistance. The operating temperature range of isoprene rubber is from −55 °C up to +80 °C.


Solution-polymerized styrene-butadiene rubber (SSBR) are the products of polymerization of butadiene-1,3 and styrene in hydrocarbon solvent with lithium-organic catalyst.

SSBR is widely used in tire, industrial rubber, cable and footwear industries. Wide use of SSBR is explained by high technical properties of the rubbers based on them.


Acrylonitrile-butadiene rubber (NBR) is essentially an acrylonitrile and butadiene copolymer obtained by emulsion polymerization method.

Due to high resistance to aggressive agents NBR is widely used for manufacture of various oil-and-petrol resistant industrial rubber products.
