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.

    Two-component RTV silicone rubber (referred to as RTV-2 rubber) is not convenient to use RTV-1 rubber, but its component proportion is rich in changes, a variety of vulcanized products can be obtained with a variety of specifications, but also can be deeply vulcanized, Therefore, it is widely used in electrical and electronic, automobile, machinery, construction, textile, chemical, light industry, printing and other industries as insulation, encapsulation, caulking, sealing, moisture-proof, anti-seismic and production of roller materials.In addition, because rTV-2 has excellent demoulding, as a soft mold material, it is widely used in the replication and manufacturing of cultural relics, handicrafts, toys, electronic appliances, mechanical parts and so on.

    In many synthetic rubber, silicone rubber is one of the best.It has tasteless non-toxic, not afraid of high temperature and withstand the characteristics of cold.Silicone rubber also has good electrical insulation, oxygen resistance, light resistance, anti-aging and mildew resistance, chemical stability, etc.Because of these excellent properties, silicone rubber has been widely and important used in modern medicine.In recent years, a variety of silicone rubber medical supplies have been successfully trial-produced by hospitals, research institutes and factories.
