CHT ALPA-SIL TRANS ÖLEND 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 Good flowing behavior and high transparency Excellent recovery capacity Very good stability to the casting resin Improved stability to curing disturbances Application: Oil-bleeding Silicone Elastomer for mould making and rapid prototyping. Very good release properties. Various B Components available. Information provided by CHT Group
