Synthetic Rubber / SKDN

Characteristics

SKDN is a synthetic rubber used for the production of rubber and technical rubber products. PBR-Nd (SKDN) is a product of butadiene solution polymerization with neodymium compounds and is used as a catalyst.  This rubber is used for productions of tires, rubber-technical articles and in other areas of application.  PBR Nd is gel-free, cis-chain content contains at least 96%.
