CHT ALPA-LSR 160201 Silicone Elastomer
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Description: This is a 2-part addition cure silicone elastomer system for Liquid Injection Molding (LSR). After mixing parts ‘A’ and ‘B’ in the correct proportions, the system will cure at elevated temperatures, usually in the range of 100 °C to 180 °C. The cycle time depends mainly on the temperature and the shape of the mould. The cured rubber exhibits excellent physical and electrical properties. Key Features Product is suitable for Liquid Injection Molding process Curing speed can be accelerated by temperature Very good mechanical properties Easy demoulding Information provided by CHT Group
