Other applications of MQ resins
It can be used to prepare organic silicon defoaming agent with high temperature resistance and strong alkali, and the defoaming agent also has the advantages of non-toxic and environmental protection. By adding high-viscosity hydroxyl silicone oil and MQ silicone resin to synthesize a network polymer with a high degree of branching, in order to improve the high temperature resistance and strong alkali resistance of the defoamer. Using MQ silicone resin containing SiH group or aralkyl group as crosslinking agent, under the action of platinum catalyst and silicone resin containing vinyl group and high phenyl group, the packaging material containing phenyl silicone resin was synthesized. The material has good compatibility and transparency, high hardness and high refractive index, and can be used for LED packaging and lens production. MQ resin-modified carboxyl silicone oil was obtained by the hydrosilylation reaction of MQ-containing silicone oil and silyl enoic acid ester under Pt catalysis. Its combination with amino silicone oil emulsion can give the fabric a better soft, smooth, plump feel.

The unique properties of silicone cover a large number of functions. The most noticeable is the excellent temperature resistance. Silicone is stable at -90-330°C. This rather wide range contrasts with most organics, which begin to solidify above 0°C and begin to fade and oxidize at 120°C. Due to its inherent ultraviolet (UV) and oxidation resistance, silicone is very weather resistant, so it is very suitable for outdoor use. Silicones do not discolor and cleave over time as organics do.

Vinyl trimethoxysilane Application field
This product is an important crosslinking agent for crosslinking polyethylene in the manufacture of wire and cable insulation and sheath materials. Compared with general peroxide crosslinking and radiation crosslinking, its crosslinking process has the advantages of simple equipment, less investment, easy control, wide density range of polyethylene, suitable for the production of fan-shaped cores with special shapes, and high extrusion speed. Because silane crosslinked polyethylene has excellent electrical properties, good heat resistance and stress cracking resistance, this product is widely used in the manufacture of wire, insulation and sheath materials.

MQ silicone resin is a relatively unique structure of silicone resin, is a four-functional siloxane chain (SiO4/2,Q) containing silicone compounds and silicone compounds containing monofunctional siloxane chain (R3SiO1/2,M) co-hydrolysis polycondensation reaction of the three-dimensional spherical structure of silicone resin. It is generally believed that MQ silicone resin is a compact sphere with a double-layer structure, its core is cage-like silica with a high silicon-oxygen bond connection density and a polymerization degree of 15-50, and the spherical shell is a R3SiO1/2 layer with a low density. MQ silicone resin has many different types due to the different organic groups R on the spherical shell: when R is all methyl, it is called methyl MQ silicone resin or MQ silicone resin for short; When part R is vinyl, it is called methyl vinyl MQ silicone resin; When part R is H, it is called methyl hydrogen MQ silicone resin; there are methyl phenyl MQ silicone resin, vinyl MQ silicone resin, phenyl MQ silicone resin, fluorine-containing MQ silicone resin, MDQ, MTQ silicone resin, and the like.

Silicon-the cornerstone of modern human civilization
Silicon-the cornerstone of modern civilization. The chip made of inorganic silicon has opened a new era of mankind and has an unprecedented and huge impact on all aspects of the world. Chips made of silicon have led to the rapid development of artificial intelligence, robots and the information superhighway. Modern high-precision military, medical, science and technology, civilian all kinds of products, none of them can leave the "chip". Without silicon, there would be no modern civilization. Silicon has triggered disruptive, revolutionary breakthroughs in many fields.
