Classification and Characteristics of Room Temperature Vulcanized Silicone Rubber


The main difference between room temperature vulcanized silicone rubber and high temperature vulcanized silicone rubber is that the former is based on polysiloxane with a smaller molecular weight, which can be vulcanized into an elastomer under the action of a crosslinking agent and a catalyst at room temperature or with a little heating. Room temperature vulcanized silicone rubber is composed of base rubber, crosslinking agent, catalyst, filler, etc. It can be divided into one-component and two-component from the packaging form.


1. Room temperature vulcanizing fluorosilicone rubber


The main features of lukewarm vulcanized fluorosilicone rubber are fuel oil resistance, solvent resistance and high temperature degradation resistance, as well as good extrusion properties.


2. Room temperature vulcanized silicone rubber


Room temperature vulcanized silicone rubber is a material that can be used for oil-contaminated parts and oil-resistant electronic components. Room temperature vulcanizing rubber has the characteristics of light resistance, ozone resistance, moisture resistance, high and low temperature resistance, and excellent electrical insulation properties.


3. Room temperature vulcanizing phenylene silicone rubber


Room temperature vulcanized phenylene silicone rubber has excellent resistance to high energy radiation. It can be applied to the atomic energy industry, nuclear power plant and space flight as a high temperature and radiation resistant adhesive sealing material and as an insulating protective layer for motors.


4. Methyl-block room temperature vulcanizing silicone rubber


Methyl-block room temperature vulcanized silicone rubber has the properties of shockproof, moisture resistance, waterproof, breathable, ozone resistance, weathering resistance, weak acid and weak alkali resistance. It has good electrical insulating properties, good adhesion, and its cost is low.


5. Methyl room temperature vulcanizing silicone rubber


Methyl room temperature vulcanized silicone rubber is an old variety of general-purpose silicone rubber, which has the advantages of water resistance, ozone resistance, arc resistance, corona resistance and weathering resistance.


6. Methyl biphenyl room temperature vulcanizing silicone rubber


In addition to the excellent properties of methyl room temperature vulcanized silicone rubber, methyl biphenyl room temperature vulcanized silicone rubber has a wider temperature range compared with methyl room temperature vulcanized silicone rubber.
