Wacker Elastosil® LR 3065/30 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Liquid silicone rubber of the ELASTOSIL® LR 3065 series are a paste-like, easily-pigmentable two component compounds with short curing times and low coefficient of friction. In comparison with ELASTOSIL® LR 3003 grades the coefficient of friction is reduced by 50 - 70 %. The vulcanizates are noted for their excellent mechanical and electrical properties. Due to the excellent compression set, there is no need to postcure technical parts. Properties: 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: Parts made from ELASTOSIL® LR 3065 are particularly suitable for the economical production of large series of injection molded articles. They can generally be used for technical applications without post-curing, but do not comply with regulations in the pharmaceutical and food industry. Information provided by Wacker Chemie AG.
