Descriptioon

Low molecular weight polyisoprene NMPI is a liquid polymerization product of isoprene with a number average molecular weight (Mn) of about 55,000 g/mol for the NMPI-500 and about 30,000 g/mol for the NMPI-70. Polymerization of isoprene is carried out in solution under the action of an anionic catalyst.

Areas of use

Low molecular weight polyisoprene NMPI is successfully used as a reactive plasticizer for nitrile, isoprene, styrene-butadiene, butadiene and isoprene- isobutylene rubbers in the production of tires, conveyor belts, seals and other rubber products. The product can be used for the manufacture of pressure-sensitive adhesives, automotive sealants, coatings, and light-curing polymer compositions. Partial or complete replacement of plasticizer oil with low molecular weight polyisoprene in the formulations of rubber compounds in the production of tires and various rubber goods provides the following advantages: increased processability of rubber compounds, increased adhesion to steel cord, improved extrudability, reduced shrinkage of rubber compounds during processing in rubber mixing equipment and increasing the mechanical strength of vulcanizates.

Packaging and transportation

Low molecular weight polyisoprene NMPI is packaged in clean, dry, tightly closed steel barrels of type 1A2 in accordance with GOST 13950 with a capacity of 100 to 216.5 dm³ or IBC with a capacity of 1.0 m³, or tank trucks.

Warranty period

Guaranteed shelf life is four years from the date of manufacture.
