Message
SKN 3345 E is essentially an acrylonitrile (31-35 %) and 1,3-butadiene copolymer obtained by emulsion polimerization method at a temperature of 32 °C with the use of phytogenous fatty acid soaps as emulsifier in accordance with the ecologically clean technology. Medium Mooney viscosity, medium content of acrylonitrile, heightened oil resistance.

Application
The manufacturing of cables, packing, sleeve gaskets, fuel hoses, roll coatings, technical plates, rubberized materials, belts, sealants, adhesives, shoe soles, plastic modification.
