Hits: 347 img

The main chain of dimethyl silicone oil molecules is composed of silicon oxygen atoms, and the side group connected to silicon is methyl. The viscosity range at 25 ℃ is 10-200 000mm2/s. Relative density d4200.93~0.975. The refractive index nD201.390~1.410. A colorless, transparent, non-toxic, and odorless oily substance. It has excellent electrical insulation performance and heat resistance, high flash point and low solidification point, and can be used for a long time in the temperature range of -50 to+200 ℃. Low viscosity temperature coefficient, high compression rate, low surface tension, good hydrophobicity and moisture resistance, lower specific heat capacity and thermal conductivity. It can be prepared by the copolymerization reaction between dimethylcyclosiloxane and hexamethyldisiloxane in the presence of a catalyst. Used as a release agent in the plastic and rubber industries; Used as an defoamer in the biochemical, pharmaceutical, and food industries; Used as shock-absorbing and damping materials in the mechanical and instrumentation industries.

What are the uses of high-temperature glue and mixed glue?

Mainly used for electronics, high-temperature wires and cables, waterproof and moisture-proof sealing in the aviation industry, and other purposes. Silicone products, silicone sealing rings, silicone tubes, silicone strips, silicone rollers, silicone sheets, silicone wheels, silicone baking trays, gilded silicone sheets, various buttons such as telephones, mobile phones, computers, TV high-pressure molds, diving goggles, silicone bracelets, silicone basins, clothing labels, silicone kitchenware and tableware, silicone medical supplies, food grade mold manufacturing such as cake molds, baby pacifiers, and some advanced transparent model designs.
