Wacker Elastosil® R 861/60 Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	These translucent compounds are highly flexible and are noted for their low compression set and improved medium resistance. Application: This compound can be used in the manufacture of molded parts, but also particularly for producing profiles, e. g. for windows and facades. Provided appropriate processing, articles produced from ELASTOSIL® R 861/60 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. Information provided by Wacker Chemie AG.
