CHT ALPA-LSR 120203 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 self adhesive to aluminum low compression set Application: ALPA-LSR 120203 is particularly suited for the production of gaskets & sealings. Self adhesive to metals without the use of primer. In order to achieve the described properties, the vulcanization time, if a hot-air oven is used, should be at least 45 minutes at 175 °C. If a heating press is used, at least 5 minutes at 175 °C are required. In addition a postcure 4 h at 200 °C is recommended. Information provided by CHT Group
