Vinyl-tris-(2-methoxyethoxy)-silane is a commonly used silicone polymer coupling agent. It can be used to improve the electrical properties and mechanical strength of EPDM, cross-linked polyethylene and other polymers or resins filled with inorganic fillers. It also has a good effect on pretreatment of clay, silicon-containing inorganic fillers and magnesium hydroxide flame retardant fillers. In

01 What is fumed silica Fumed silica is an amorphous silicon dioxide powder obtained by burning silicon tetrachloride and methyl silicon trioxide in an oxygen-hydrogen flame. The smallest particle size of this powder can reach the nanometer level, and it is a commonly used nano-inorganic material. 02 The relationship between fumed silica and carbon black Fumed silica and carbon black have man

Silicone modified waterborne alkyd resin. Water-based alkyd resins are cheap and easy to obtain, and have excellent appearance, flexibility and brushability, but poor gloss and color retention and chemical resistance; in addition, the ester bonds of water-based alkyd resins are prone to hydrolysis, resulting in poor water resistance. The grafting of silicone resin or embedding in the main chain

The way to increase the hardness of rubber 1. Raw rubber High-hardness rubber formulations often require a large amount of filler and reinforcing agent, and the raw rubber should choose a grade with a high Mooney viscosity. For example, EPDM should use grades with high Mooney and high ethylene content; NBR can choose grades with high Mooney and high acrylonitrile content. Sometimes according

Part.1 Structure Polysiloxane is a twisted helical straight chain structure that can rotate freely around the main chain, so the main chain is very soft, which determines that polysiloxane can be an excellent softener for fabrics. The high polarity of the amino group in amino-modified polysiloxane enables it to interact with hydroxyl groups, carboxyl groups, cyano groups, ester groups, amide g

Vulcanization temperature: Vulcanization temperature directly affects product performance, vulcanization speed and production efficiency. Too high temperature vulcanization will cause adverse effects: 1. Accelerate the cracking of rubber and reduce the performance of rubber 2. Shorten the scorch period and affect the flow of rubber 3. Thick products are easy to cause cra

Liquid silicone has excellent transparency, tear resistance, resilience, anti-yellowing, thermal stability, water resistance, good air permeability, heat aging resistance and weather resistance, while moderate viscosity, good fluidity, easy to operate, transparent products high sex. Utilizing the various properties of liquid silicone, injection molding liquid silicone can also be widely used in

This produces silicic acid and hydrogen chloride. Trichlorosilane is a compound containing silicon, hydrogen and chlorine elements. It is soluble in most organic solvents such as benzene and ether. The relative density is 1.37, and the relative density is 4.7. It is stable in nature. Strongly irritating to eyes and mucous membrane of respiratory tract. At high concentrations, it can cause corne

With the development of the electronics industry, the requirements for the stability and reliability of components and complete machines are getting higher and higher. Therefore, it is necessary to potting electronic components or assembly parts to avoid moisture, impurities and various chemicals in the atmosphere. Pollution and erosion of the atmosphere, so that the whole machine can stably pe
