We have a long history in chemical auxiliaries, starting with production of peroxide in 1966 for use as high pressure polyethylene catalyst. Since then, many new chemical auxiliaries have been added to our portfolio. They are used to initiate polymerization reactions for production of plastics, hardening of thermoset composites and improve the properties of plastics and rubbers. We offer the complete product portfolio of hydroperoxides, ketone peroxides, alkyl peroxides, acyl peroxides, ester peroxides.
