Wacker Elastosil® LR 3005/40 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Liquid silicone rubber of the ELASTOSIL® LR 3005 series are a paste-like, easily-pigmentable two component compounds with extremely short curing times. 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: Narrow Shore hardness range. 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 3005 are particularly suitable for the economical production of large series of injection moulded 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.
