107 silicone rubber, also known as room temperature vulcanized silicone rubber, commonly known as raw rubber, is a special rubber that can be vulcanized at room temperature. Its chemical composition is polydimethylsiloxane with hydroxyl dimethylsiloxy as the end group.
Compounding rubber: A special rubber that is vulcanized at high temperatures and is made from raw rubber as the main raw material and white carbon black as the reinforcing filler through the compounding process.
107 glue can be used directly as a commodity or as an intermediate to produce various condensation type silicone rubber products.
Characteristics of 107 silicone rubber:
-
Room temperature vulcanized silicone rubber has excellent insulation, arc resistance, corona resistance, water resistance, and weather aging resistance. It can be used within the range of -60°C to 250°C and has the characteristics of waterproof, dustproof, and cold-proof.
-
Arc resistance: The ability of plastic materials to resist deterioration caused by the action of high-voltage arcs. It is usually expressed by the time required for the arc flame to cause carbonization on the material surface until the surface conducts electricity and the arc disappears, and the unit is seconds.
-
Corona resistance: The property of insulating materials to resist quality degradation when subjected to corona discharge.
Uses of 107 silicone rubber:
-
As the main raw material in RTV silicone rubber, defoamers, and silicone products.
-
Due to the good electrical insulation of organosilicon, it can be used as insulation, moisture-proof, shock-proof, and heat-resistant filling and sealing materials in radio, electronic instruments, semiconductors and other electronic components and assemblies.
-
As rubber roller materials in the automotive and machinery industries.
-
As rubber roller materials in the textile, plastic, and printing industries.
-
Caulking and sealing materials in the construction industry.
-
It has very good demolding properties for two-component silicone rubber and is suitable for manufacturing precision molds and impression materials.
