phenol

Phenol is an important organic chemical raw material, widely used in the production of phenolic resin and bisphenol A, in which bisphenol A is important raw material for polycarbonate, epoxy resin, polysulfone resin and other plastics. In some cases the phenol is used to produce iso-octylphenol, isononylphenol, or isododecylphenol through addition reaction with long-chain olefins such as diisobutylene, tripropylene, tetra-polypropylene and the like, which are used in production of nonionic surfactants. In addition, it can also be used as an important raw material for caprolactam, adipic acid, dyes, medicines, pesticides and plastic additives and rubber auxiliaries.

Propylene glycol sales

Propylene glycol is used for similar applications as other glycols. Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The use amount in this area accounts for about 45% of the total consumption of propylene glycol. Such unsaturated polyester is used extensively for reinforced plastics and surface coatings. Propylene glycol is excellent in viscosity and hygroscopicity and is non-toxic, and thus is widely used as hygroscopic agent, antifreeze, lubricants and solvents in the food, pharmaceutical and cosmetic industry. In the food industry, propylene glycol reacts with fatty acid to give propylene ester of fatty acids, and is mainly used as food emulsifier; Propylene glycol is a good solvent for flavorings and pigments. Propylene glycol is commonly used as solvents, softeners and excipients, etc. in the pharmaceutical industry for the manufacture of various types of ointments and salves. Propylene glycol is also used as a solvent and a softener for cosmetic since it has good mutual solubility with various spices. Propylene glycol is also used as tobacco moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking ink. Aqueous solution of propylene glycol is an effective anti-freeze agent.

Styrene

Styrene is an important monomer of synthetic rubber, adhesives and plastics. It is used for the synthesis of styrene butadiene rubber and polystyrene resin, polyester glass fiber reinforced plastics and coatings. It is used for preparing polystyrene, ion exchange resin, and foam polystyrene. It is also used for copolymerization with other monomers to produce various engineering plastics, such as copolymerization of acrylonitrile and butadiene to produce ABS resin, widely used in various household appliances and industries. Copolymerization with acrylonitrile, obtained SAN is a resin with shock resistance and bright color. The SBS produced by copolymerization with butadiene is a thermoplastic rubber, which is widely used as a polyvinyl chloride and acrylic modifier. SBS and SIS thermoplastic elastomers are made with butadiene and isoprene copolymerization, and as a crosslinking monomer, styrene is used in the modification of PVC, polypropylene, and unsaturated polyester. Syrene is used as a hard monomer for the production of styrene acrylic emulsion and solvent pressure sensitive adhesive. Emulsion adhesive and paint can be prepared by copolymerization with vinyl acetate and acrylic ester. Styrene is one of the most commonly used vinyl monomers in the scientific field, used in various modified and composite materials. In addition, a small amount of styrene is also used as perfume and other intermediates. By chloromethylation of styrene, cinnamyl chloride is used as an intermediate for the non anesthetic analgesic strong pain determination, and styrene is also used as an antitussive, expectorant and anticholinergic original medicine in stomach Changning. It can be used to synthesize anthraquinones dye intermediates , pesticide emulsifiers, and styrene phosphonic acids ore dressing agent and copper plating brighteners.

Toluene

Toluene is derived from coal tar as well aspetroleum. It occurs in gasoline and manypetroleum solvents. Toluene is used to producetrinitrotoluene (TNT), toluene diisocyanate,and benzene; as an ingredient fordyes, drugs, and detergents; and as an industrialsolvent for rubbers, paints, coatings, andoils. Toluene has numerous applications in the chemical and petroleum industry, with approximately 6 million tons used annually in the United States and 16 million tons used globally. The major use of toluene is as an octane booster in gasoline. Toluene has an octane rating of 114. Toluene is one of the four principal aromatic compounds, along with benzene, xylene, and ethylbenzene, that are produced during refining to enhance gasoline's performance. Collectively, these four compounds are abbreviated as BTEX. BTEX is a major component of gasoline, forming about 18% by weight of a typical blend. Although the proportion of the aromatics is varied to produce different blends to meet geographic and seasonal requirements, toluene is one of the major components. A typical gasoline contains approximately 5% toluene by weight. Toluene is a primary feedstock used to produce various organic compounds. It is usedto produce diisocyanates. Isocyanates contain the functional group ?N = C = O, and diisocyanatescontain two of these. The two main diisocyanates are toluene 2,4-diisocyanate andtoluene 2,6-diisocyanate. The production of diisocyanates in North America is close to a billionpounds annually. More than 90% of toluene diisocyanate production is used for makingpolyurethanes foams. The latter are used as flexible fill in furniture, bedding, and cushions.In rigid form it is used for insulation, hard shell coatings, building materials, auto parts, androller skate wheels. In manufacture of benzoic acid, benzaldehyde, explosives, dyes, and many other organic Compounds; as a solvent for paints, lacquers, gums, resins; thinner for inks, perfumes, dyes; in the extraction of various principles from plants; as gasoline additive.

Anti-aging agent 4020

1, 4020 for amine antioxidant varieties in the performance of one of the general-purpose antioxidant varieties, its anti-ozone-aging cracking and flexural cracking performance is slightly inferior to antioxidant 4010NA, but stronger than antioxidant 4010. It also has good protection effect on thermal oxygen and weathering aging, and has passivation effect on varicose metal. It is suitable for natural rubber, paraben rubber, butadiene rubber, nitrile rubber, neoprene rubber. Used with paraffin wax (mixed wax and microcrystalline wax with more branched chains), it can enhance the protection effect on static. 2、4020 is applied to rubber products that are subjected to stress and cyclic deformation under dynamic and static conditions, and is the best choice for rubber tread, sidewall, inner tube and conveyor belt protection systems. Compared with antioxidant 4010NA, water extraction resistance (or washing loss rate) is better, can achieve the effect of long-lasting protection, antioxidant 4020 can be used as a stabilizer for synthetic rubber. 3, 4020 low melting point, easy to disperse, dense refining machine or open refining machine can achieve uniform dispersion of the mixing effect. With paraffin wax and good, considering the comprehensive protection efficiency, usually and other antioxidants such as antioxidant RD, antioxidant A, antioxidant BLE and use. With antioxidant MB can improve the heat resistance of products. 4、4020 application range includes pneumatic tire parts, solid tires, conveyor belts, hoses, cables, automotive cushion brackets, rubber joints and general rubber industry products, these products are in continuous or intermittent dynamic working conditions, the need for ozone protection. 5、4020 is an effective stabilizer for a wide range of soluble and emulsion polymers. 6、The antioxidant activity of 4020 is higher than that of quinoline or diphenylamine antioxidants. Make the rubber has good resistance to copper and other heavy metal catalytic degradation performance. 7、4020 will discolor the rubber and cause serious contact and migration contamination.
