Rubber Products

Stern produces a range of anti-tack chemicals that complies with the requirements of most rubber compounders.

Our release agents are easy to disperse in water and are low dusting. Most mixtures are completely meltable at low temperatures and leave no trace in the final compound.

Batch off powders

Stern offers a range of floatable and water dispersible batch off powders for slap stocks. These anti-tack compounds are attached to the uncured rubber surface that allows for release or separation during storage. Our products are developed for several polymers and applications.

Mixture of calcium soap and surfactants. Around 40% solids with good stability and low viscosity. Small particle size distribution and good releasing properties.

Mixture of calcium soap and surfactants. Around 50% solids with good stability and medium viscosity. Small particle size distribution and good releasing properties.

Mixture of zinc soap and surfactants. Around 40% solids with good stability and medium viscosity. Small particle size distribution and good releasing properties.

Mixture of clays, calcium carbonate and surfactants. Powder form with good dispersibility in water. Small particle size distribution, good film formation and excellent releasing properties.
