Product Range

Nitrile Rubber (NBR)

Sibur

Sibur NBR Standard Grades

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

Sibur NBR Fast Curing Grades

Fast Curing grades significantly reduce tendency to residue formation on the
curing surface of rubber molds and allow to reduce production cycle time.
Contains non-staining antioxidant.

Sibur NBR-PVC Grades

NBR-PVC is a homogenous mixture of NBR with PVC obtained by joint coagulation of NBR latex with PVC latex. SIBUR technology of production NBR-PVC blend allows to significantly increase the homogeneity of PVC distribution in rubber leading to better properties of final products. Contains non-staining antioxidant.

Sibur Powder NBR (Linear)

Powdered nitrile rubber that is used as an impact modifier and non-migrating plasticizer. Compatible with a number of different polymers. Contains nonstaining antioxidant.

Sibur NBR Crosslinked Grades

NBR Crosslinked obtained by modification on the latex stage. Provides good dimensional stability and impact modification, improves the surface of final products. Upon customer‘s requirements, NBR Crosslinked can be produced in powder or bales.

Isoprene Rubber (IR)

Sibur

Isoprene Rubber (IR) is an excellent natural rubber substitute with stable performance resulting in sustainable high quality of finished goods. Isoprene rubber is produced by using the complex catalysts of stereospecific polymerization in solvents.

Regular Butyl Rubber (IIR)

Butyl rubber is a synthetic polymer, a copolymer of isobutylene with isoprene. The key advantage butyl rubber offers is superior air-barrier performance with excellent flex properties. Butyl Rubber abbreviated as IIR (Isobutylene-Isoprene
copolymer) is extensively used to manufacture tire’s Inner Tube. It offers matchless ozone & weather resistance along with heat stability.

Bromobutyl Rubber (BIIR)

Bromobutyl rubber is a derivative of butyl rubber which is produced by brominating butyl rubber in a continuous halogenation process. Bromobutyl is very similar to Chlorobutyl in structure and properties. However, it has higher reactivity than Chlorobutyl therefore offering highly versatile curing system properties.
