Wacker Elastosil® LR 3092/65 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Liquid silicone rubber ELASTOSIL® LR 3092/65 A/B is a paste-like two-component compound with short curing times. The vulcanizates are noted for good mechanical properties and for excellent heat resistance within a temperature range of -55 °C to +230 °C, and for a short time up to +300 °C. Outstanding low compression sets can be achieved after post curing. Application: ELASTOSIL® LR 3092/65 A/B is particularly suitable for the economical production of large series of articles for the automotive industry, e. g. inter cooler gaskets.
