These translucent compounds are highly flexible and are noted for their low compression set and improved media and coolant resistance.


Specific features of ELASTOSIL® R 861/60 S

  • Coolant resistant
  • Food-contact
  • Steam resistant
  • Ultra-low compression set

This compound can be used in the manufacture of molded parts, but also particularly extrusion, for producing profiles, e. g. for windows and facades.

Provided appropriate processing, articles produced from ELASTOSIL® R 861/60 S can be used for food contact applications in accordance with the Recommendation "XV. Silicones" of the BfR and FDA 21 CFR § 177.2600 under observance of any given limitations on extractable and volatile substances. Furthermore, the product contains low levels of residual toluene which has to be completely removed from the final food contact article.

To obtain optimum compression set values it is advisable to post-cure for 4 hours at 200°C. We recommend to use 1.5 % Curing Agent E for the manufacture of extrudates, and 0.7 % C1 or 1.2 % C6 for molded parts.

For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".
