Krasnoyarsk Synthetic Rubber Plant forming part of SIBUR Holding JSC has become the first to launch the production of butadiene-nitrile rubber powder (BNRP) in Russia.
The production process for the new unit with an estimated capacity of 500 kg/h was designed by Pallmann Maschinenfabrik of Germany, a leading manufacturer of equipment for grinding various materials.
The new product to be obtained from the company's own raw material will enable the company to increase the volume of sales on the domestic market for account of BNRP import substitution, as well as to decrease the commercial risks if a drop in demand for briquetted rubber.
Butadiene-nitrile rubber powder (BNRP) comprises the rubber ground on special-purpose equipment and having a particle size less than 1 mm. At present, BNRP has widespread application for improving the viscoelasticity of glues, mastics, fabricated rubber products, footwear, as well as PVC, ABS resin and other polymer articles.
The raw material for BNRP is butadiene-nitrile rubber which is ground to obtain a powder, as well as fine fractions of chalk, talc and suspended PVC used as a parting agent.
