Silicone rubber can be divided into high temperature heating vulcanization (HTV) and room temperature vulcanization (RTV) according to its vulcanization temperature. High temperature rubber is mainly used to manufacture various silicone rubber products, while room temperature rubber is mainly used as an adhesive , potting material or mold application. 1. Hot Vulcanized Silicone Rubber (HTV) Hot vulcanized silicone rubber (HTV) is the most important type of silicone products, and methyl vinyl silicone rubber (VMQ) is the most important type of HTV, commonly known as high temperature rubber. Methyl vinyl silicone rubber (raw rubber) is a colorless, odorless, non-toxic, and free of mechanical impurities. It is smelted, then heated to press molding or extrusion molding, and then made into various finished products through two-stage vulcanization. The finished product has excellent electrical insulation, strong resistance to arc, corona, and electric spark, waterproof, moisture-proof, impact resistance, shock resistance, psychological inertia, air permeability and other functions. It is mainly used in aviation, instrumentation, electronic appliances, sailing, metallurgy, machinery, automobiles, medical and health care and other parts. It can be used as sealing rings, gaskets, pipes and cables of various shapes, as well as human organs, blood vessels, and breathable membranes. As well as rubber molds, mold release agents for fine forging, etc. 2. Room temperature vulcanized silicone rubber (RTV) RTV silicone rubber is generally divided into two categories: condensation type and addition type. Condensation type RTV silicone rubber is characterized by the condensation reaction between silicon hydroxyl and other active substances. It can be cross-linked into an elastomer at room temperature. The product is divided into one-component packaging and two-component packaging. Way. One-component room temperature vulcanized silicone rubber (RTV-1 for short) is one of the first products in condensation-type liquid silicone rubber. Ordinary is made up of base polymers, cross-linking agents, catalysts, fillers and additives. The product is packaged in a sealed hose, extruded during use, and can be self-vulcanized into an elastomer after contact with air, which is extremely convenient to use. Vulcanizate can be used for a long time in the temperature range of (-60~+200℃), has excellent electrical disconnection function and chemical invariance, water resistance, ozone resistance, weather aging resistance, and is superior to a variety of metal and non-metallic materials of adhesiveness. It is mainly used for the coating of various electronic components and electrical equipment, and the encapsulation material has the effect of insulating, moisture-proof and shock-proof; as the surface maintenance material of semiconductor devices; it can also be used as sealing filler and elastic adhesive, etc. The addition type room temperature adhesive is based on linear polysiloxane with vinyl as the base adhesive, and hydrogen-containing siloxane as the cross-linking agent. In the presence of a catalyst, a cross-linking reaction occurs at room temperature to medium temperature to become an elastomer. It has excellent heat resistance, hydrophobicity, electrical insulation, and because of the introduction of active end groups, it has excellent physical and mechanical functions, especially in tensile strength, relative elongation and tearing strength. improvement. It is suitable for a variety of vulcanization methods, such as radiation vulcanization, peroxide vulcanization and addition vulcanization, and is widely used in heat resistance, moisture resistance, electrical insulation, and high-strength silicone rubber products.
