PETER GREVEN – Your partner for rubber additives

Oleochemical additives are also indispensable additives in the rubber industry:

Metallic soaps are used because of their excellent separation properties and good compatibility in rubber as a release agent. Furthermore, they also serve as a vulcanising agent and act as a lubricant.

In addition to the metallic soaps, processing aids from special stearic acids through to glycerine and right up to additive mixtures are used to ensure an uninterrupted production process.

Our most important brands for the rubber industry:

LIGAFLUID® and LIGASTAR®

Our additives are used in

  • Styrene-butadiene-rubber (SBR)
  • Poly-butadiene-rubber (PBR)
  • Ethylene-propylene-diene-monomer (EPDM)
  • Medical rubber products (e.g., blood bags, infusion tubing)
