Liquid silicone rubber generally includes two categories of condensation and molding, new good silicone to give you a detailed introduction to these two categories.

      Add molding silicone rubber is a vinyl linear polysiloxane as the base rubber, with hydrosiloxane as the crosslinking agent, in the presence of a catalyst at room temperature to medium temperature crosslinking reaction and become an elastomer.It has good heat resistance, hydrophobicity and electrical insulation. At the same time, due to the introduction of active end group, it has excellent physical and mechanical properties, especially in the tensile strength, relative elongation and tear strength has been significantly improved.

      It is suitable for a variety of curing methods, such as radiation curing, peroxide curing and molding curing, widely used in heat resistance, moisture resistance, electrical insulation, high strength silicone rubber products and so on.

      Condensation type silicone rubber is characterized by condensation reaction between silicon hydroxyl and other active substances, which can be crosslinked to become elastomers at room temperature. The product is divided into two forms of single-component packaging and two-component packaging.Rtv-1 rubber is one of the main products of condensed liquid silicone rubber.It is usually made of basic polymers, crosslinking agents, catalysts, fillers and additives.The product is packed in a sealed hose, extruded when used, and can be self-vulcanized into elastomer after contact with air, which is very convenient to use.Vulcanizates can be used in the temperature range (60 ~ +200℃) for a long time, with excellent electrical insulation performance and chemical stability, water resistance, ozone resistance, climate aging resistance, a variety of metal and non-metal materials have good adhesion.Mainly used as a variety of electronic components and electrical equipment coating, sealing material insulation, moisture, shock;As a surface protection material for semiconductor devices;It can also be used as sealing filler material and elastic adhesive.
