1-Ethenoxy-2-methylpropane is mainly used in organic synthesis, polymerization and copolymerization to produce polyethylene ether, coatings, additives, plasticizers, etc.

Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Its trade name in China is polypropylene fiber.

UV-234 is a light yellow powder with a melting point of 135-145 ℃. Soluble in chloroform, dichloromethane, benzene, ethyl acetate and other organic solvents, slightly soluble in alcohols, insoluble in water. Benzotriazole UV absorbers are suitable for polycarbonate, polyvinyl chloride, polyformaldehyde, polyamide, polyester, coatings, etc.

This product is used as a chemical reagent, as well as in dye and organic synthesis. It is widely used in the synthesis of pharmaceuticals, pesticides, stabilizers for polymerization and catalysts for organic synthesis (esters, etc.). It is also used as an intermediate in medicine and coatings and a resin curing agent.

Ethylene glycol phenyl ether is a typical high boiling point organic solvent, which has been widely used in Europe and America as early as 1970s. It is a kind of colorless and transparent liquid with rose fragrance, low volatility and high boiling point. Because it can be miscible with many organic solvents and has strong permeability, it has outstanding comprehensive performance compared with isophorone, DBE and benzyl alcohol, and can be used instead of all performance. Ethylene glycol phenyl ether has excellent solubility for acrylic resin, nitrocellulose, ethyl cellulose, epoxy resin, alkyd resin, phenoxy resin and other resins, and can be miscible with alcohol and ether, commonly known as "universal solvent". This product can be used as water-based coating and ink film forming AIDS, perfume and fragrance setting agents, ink fluence, pharmaceutical antiseptic fungicides, electronic cleaning agents and ink slow drying agents.
