Liquid silicone is relatively solid for the high-temperature vulcanized silicone rubber, which is liquid glue, with good fluidity, curing faster, more secure environment, can fully meet food grade requirements.
　　Liquid silicone can be used for coating, dipping and pouring. For example, a viscosity of 0.07 to 50 Pa s / 25 ℃ of the hydroxy-terminated polydimethylsiloxane, double-pyrrolidone with methyl vinyl silane as chain growth agents, organic peroxides such as benzoyl peroxide acid, 25 - dimethyl base 5 - di-tert-butyl peroxy hexane as a vulcanizing agent, plastic material such fluidity, low viscosity, the curing process in the chain growth reactions occur simultaneously, so the availability of high molecular weight elastomers with good mechanical properties.
　　Liquid silicone chain growth in two-pyrrolidone methyl vinyl silane agent, by the pyrrolidone and methyl vinyl dichlorosilane in the presence of triethylamine from the reaction, the product is easy to hydrolysis, so the need to be stored in a dry airtight container, this compound the pyrrolidone base at room temperature with polydimethylsiloxane hydroxyl-terminated within the slow reaction, the reaction rate is accelerated with increasing temperature. In theory, this reaction can be carried out continuously, until you get infinite molecular weight. Methyl vinyl pyrrolidone vinyl silane in the curing reaction can be used as the activation point, to promote cross-linked polydimethylsiloxane to produce high molecular weight elastomer. As with the hydroxy-pyrrolidone-based reaction is very slow at room temperature, it is added after mixing the components of plastic material with a longer period of application, in one hour the viscosity of the compound is essentially the same, but still maintain a good liquidity can be injected into the tiny pores. The rubber mixture is heated at 150 ℃ for 10 minutes vulcanized into elastomers.
