Description

SKDSN rubber is a low-molecular-weight product of the polymerization of butadiene in solution under the influence of an anionic catalyst, providing a content of 1,2-vinyl units in the polymer chain of at least 40%.
Rubber at ordinary temperatures is a thick viscous mass. SKDSN has high heat resistance and retains its properties when heated repeatedly for a long time.

Areas of use

Coagent in EPDM rubber compounds, solid electrical sealants, defoamers for paint coatings, reactive plasticizer for UV-curable flexographic printing plates, automotive sealants and adhesives cured with sulfur or hydrogen peroxide, coagent in rubbers and elastomers, curable by sulfur or hydrogen peroxide. SKDSN is also used in the electrical industry as a component of quick-hardening dielectric coatings, impregnating resins, etc., as well as in the tire and rubber industries as an additive - a plasticizer that improves the adhesive properties of rubber. Polymer adhesion enhancers based on this type of polybutadiene and especially those containing functional groups are well compatible with almost all types of synthetic and natural rubbers.

Packaging And Transportation

SKDSN rubber is packaged in steel barrels with a capacity of 200 to 275 dm³. The product is transported by any type of transport.

Warranty period

The guaranteed shelf life of rubber is three years from the date of manufacture.
