Wacker Elastosil® LR 3023/60 A/B Liquid Silicone Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)
Material Notes:	Liquid silicone rubbers of the ELASTOSIL® LR 3023 series are paste-like, easily-pigmentable two component compounds with extremely short curing times and excellent coolant resistance. Their vulcanizates are opaque with average mechanical properties and they are noted for low compression sets and so there is no need to post-cure technical parts. Application: ELASTOSIL® LR 3023 series are particularly suitable for the economical production of gaskets and rubber parts which are used for radiators in the automotive industry. Note 1: Cooling agent immersion (after immersion in Glysantin G 40 / distilled Water = 50 : 50 / 108 °C / reflux Note 2: Cooling agent immersion (after immersion in Glysantin G 40 / distilled Water = 50 : 50 / 125 °C / autoclave) Information provided by Wacker Chemie AG.
