- Application Details
- 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 861/70 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.
Processing
- 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.
