RTV-2 / LSR Silicone Rubber

LSR(liquid silicone rubber) is also called injection-molding silicone rubber. LSR is a heat-curing rubber, but it is based on liquid phase and has much lower viscosity than HTV or other elastomers, which enables to flow into the injection mold easily and continuously and to make automatic molding.These properties result in higher productivity and cost effectiveness of finished products. Because it makes no by-products and has excellent properties, LSR is displacing from HCR in a number of applications

RTV-2 is two-component room temperature vulcanizing silicone. Depending on its curing mechanism, two types of RTV-2 are available- a condensation cure type and an addition cure type. The condensation cure type is strongly dependent on the catalyst and produces by-products like alcohol, while the addition cure type is dependent on temperature and produces no by -products. RTV-2 is capable of deep section cure and its cure rate can be controlled. Also, it provides excellent electrical insulation, heat resistance, cold resistance, weatherability, and impact absorption, as the unique features of silicones. These properties result in superior ease of use for various applications and improvement of the quality and productivity of finished products. RTV-2 is used primarily as electrical insulating and potting materials for electrical and electronics, vacuum casting mold and various forming molds.
