The main classification and application of silicone rubber

Hits: 188 img

According to its vulcanization temperature, silicone rubber can be divided into high temperature (heating) vulcanization type and room temperature vulcanization type. High temperature glue is mainly used to manufacture various silicone rubber products, while room temperature glue is mainly used as adhesive and potting. Use of materials or molds.
 
(1) Thermal vulcanized silicone rubber (HTV)
Hot vulcanized silicone rubber (HTV) is the most important type of silicone products. Methyl vinyl silicone rubber (VMQ) is the most important type in HTV, commonly known as high temperature glue. Methyl vinyl silicone rubber (green rubber) is a colorless, odorless, non-toxic, non-mechanical impurities. The raw rubber is mixed with additives such as a suitable reinforcing agent, structure control agent and vulcanizing agent as needed. Refining, then heating molding or extrusion molding, and then two-stage vulcanization to make various products. Its products have excellent electrical insulation, anti-arc, corona, electric sparking ability, waterproof, moisture-proof, impact resistance, shock resistance, physiological inertness, gas permeability and other properties.
Mainly used in aviation, instrumentation, electronics, marine, metallurgy, machinery, automotive, medical and other departments, can do a variety of shapes of seals, gaskets, tubes, cables, but also human organs, blood vessels, gas permeable membranes and Rubber molds, precision casting release agents, etc.

(2) Room temperature vulcanized silicone rubber (RTV)
 Room temperature vulcanized silicone rubber generally includes two types of condensation type and addition type.
The addition molding room temperature glue is based on a linear polysiloxane having a vinyl group as a crosslinking agent, and a hydrogen siloxane is used as a crosslinking agent, and a crosslinking reaction occurs at room temperature to a medium temperature in the presence of a catalyst to become an elastomer. It has good heat resistance, water repellency and electrical insulation, and it has excellent physical and mechanical properties due to the introduction of active end groups, especially in terms of tensile strength, relative elongation and tear strength. Improvement. It is suitable for a variety of vulcanization methods, such as radiation vulcanization, peroxide vulcanization and addition vulcanization, widely used in heat, moisture, electrical insulation, high strength silicone rubber products.

The condensation type room temperature vulcanization silicone rubber is characterized by a condensation reaction between a silanol group and other active materials, and can be crosslinked into an elastomeric silicone rubber at room temperature. The product is divided into a single component package and a two component package. form. One-component room temperature vulcanized silicone rubber (RTV-1 glue for short) is one of the main products in condensed liquid silicone rubber. Usually formulated from base polymers, crosslinkers, catalysts, fillers and additives. The product is packaged in a sealed hose. It is extruded during use and can be vulcanized into an elastomer after contact with air. It is extremely convenient to use. Vulcanized rubber can be used for a long time in the temperature range of (–60~+200°C). It has excellent electrical insulation properties and chemical stability. It is resistant to water, ozone and weathering. It has good adhesion to various metal and non-metal materials. Connectivity. Mainly used for the coating of various electronic components and electrical equipment, the encapsulation material is insulated, moisture-proof and shockproof; as a surface protection material for semiconductor devices; it can also be used as a sealant and elastic adhesive.
