The most important use is as a synthetic rubber and plastic monomer, used to produce styrene butadiene rubber, polystyrene, Styrofoam; also used for copolymerization with other monomers to create a variety of different uses of engineering plastics. Such as with acrylonitrile, butadiene copolymerization in ABS resin, widely used in various household appliances and industrial; SAN copolymer obtained with acrylonitrile is impact-resistant, bright color resin; and butadiene copolymer obtained SBS is a thermoplastic rubber, widely used as a polyvinyl chloride, polypropylene modifier and so on. In addition, a small amount of styrene is also used as an intermediate for perfumes and the like. Styrene is chloromethylated to give cinnamyl chloride as a non-narcotic analgesic painkillers, styrene is also used as antitussive and expectorant easy cough, anticholinergic Changning’s original drug. It can also be used as a hard monomer for the manufacture of styrene acrylic emulsion and solvent-based pressure-sensitive adhesives, or as a crosslinking monomer for unsaturated polyester resins. For organic synthesis and resin synthesis, for the preparation of copper plating brightener, leveling and light from the role.
For the manufacture of styrene-acrylic emulsion and solvent-based pressure-sensitive adhesive hard monomer can also be used as unsaturated polyester resin crosslinking monomer. For the manufacture of polystyrene, Styrofoam, Styrene-butadiene rubber; Copolymerization with acrylonitrile and butadiene to ABS resin; Copolymerization with butadiene and isoprene to produce SBS and SIS thermoplastic elastomers; Vinyl ester and acrylic copolymer emulsion manufacturing adhesives and coatings. Also used as unsaturated polyester crosslinking monomer and polyvinyl chloride and polypropylene modified, as well as the use of synthetic perfume intermediates and so on. Styrene is chloromethylated to give cinnamyl chloride as a non-narcotic analgesic painkillers, styrene is also used as antitussive expectorant drug easy cough, anticholinergic Changning’s original drug. For the synthesis of styrene-butadiene rubber and polystyrene resins, polyester fiberglass and coatings, synthetic dye intermediates anthraquinone, pesticide emulsifier, medicine, dressing agent styrene phosphonic acid. For the system of polystyrene, synthetic rubber, ion exchange resins.
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
