Wacker Elastosil® LR 7665 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Product description: ELASTOSIL® LR 7665 A/B is a pourable, readily pigmentable two-component compound with very short curing times. The vulcanizates are noted for their extremely high transparency and excellent electrical properties. When heat stabilizers are added, the products can be used within a temperature range of - 55 °C to +230 °C, for a short time up to +300 °C. Application: This grade is particularly suitable for the economical production of large series of injection molded articles. Parts made form ELASTOSIL® LR 7665 A/B can be used for technical applications. These articles are also suitable for use in conjunction with foodstuffs. Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances. Furthermore the product contains residual toluene which has to be completely removed from the final food contact article. Information provided by Wacker Chemie AG.
