CHT ALPA-SIL MINT Silicone Molding Rubber
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Description: This is a pourable 2-part addition cure silicone elastomer system. After mixing parts ‘A’ and ‘B’ in the correct proportions, the system will cure at ambient temperatures within 24 hours, but the rate of cure can be accelerated by heat. The cured rubber exhibits excellent physical and electrical properties. Key Features Crosslinks at temperatures as of 23 °C/77°F Easy handling due to low viscosity Simple mixing of components Easy casting of the mix Application: Mould making applications Information provided by CHT Group
