    Organosilicon materials have unique structures:


    (1) The high energy polysiloxane main chain is shielded by sufficient methyl groups on Si atoms;


    (2) C-H is non-polar, resulting in very weak intermolecular interaction force;


    (3) Si-O bond length is long, Si-O-Si bond Angle is large.


    (4) Si-O bond is a covalent bond with 50% ionic bond characteristics (covalent bond has directivity, ionic bond has no directivity).


    The characteristics of


    Because of organic silicon unique structure, with the performance of the inorganic materials and organic materials, with low surface tension, small viscosity-temperature coefficient, high compressibility and high gas permeability basic properties, and has high and low temperature resistance, electrical insulation, resistance to oxidation stability, weather resistance, flame retardant, hydrophobic, corrosion resistance, non-toxic, tasteless, and physiological inertia and other excellent properties, Widely used in aerospace, electronics and electrical, construction, transportation, chemical, textile, food, light industry, medical and other industries, where silicone is mainly used in sealing, bonding, lubrication, coating, surface activity, demoulding, defoaming, foam suppression, waterproof, moisture-proof, inert filling, etc..With the continuous growth of the number and variety of organosilicon, the application field is constantly broadening, forming a unique and important product system in the field of new chemical materials, many varieties are irreplaceable and essential to other chemicals.


    Organic silicon is also required for organism metabolism, and the chemical formula of such organic silicon is usually CH3(SiOH)3.Silicone plays an important role in various bodily functions and is directly related to mineral absorption.The average human body contains about seven grams of silicon, far more than other important minerals such as iron.Iron and silicon are essential elements in the body and are essential for maintaining a normal metabolism.


    According to the different forms of organic silicon materials, they can be divided into: silane coupling agent (organic silicification reagent), biological active silicone, silicone oil (silicone grease, silicon emulsion, silicon surfactant), high temperature vulcanized silicone rubber, liquid silicone rubber, silicone resin, complex, etc..
