Wacker Elastosil® LR 3003/25 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Liquid silicone rubbers of the ELASTOSIL® LR 3003 series are paste-like, easily-pigmentable two component compounds with short curing times. Their vulcanizates are noted for their high transparency and excellent mechanical and electrical properties. Properties: Narrow Shore hardness range from 22 to 28 Shore A (25 ± 3 Shore A). The products can be used within a temperature range of - 55 °C to + 210 °C. The addition of heat stabilizers at service temperatures of more than 180 °C is recommended. Application: These grades are particularly suitable for the economical production of large series of injection molded articles. Parts made from ELASTOSIL® LR 3003/25 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. Information provided by Wacker Chemie AG.
