Dimethyl Sulfone Suppliers and Manufacturers

Application: 1. Propylene carbonate is a polar solvent. It can be used as a plasticizer, spinning solvent, water-soluble dye and plastic dispersant. It can also be used as an oily solvent and an extractant for olefins and aromatics. 2. Propylene carbonate is used as the electrolyte of the battery to withstand the harsh light, heat and chemical changes of the Chemicalbook. It also has certain uses in geological beneficiation and analytical chemistry. 3. In addition, propylene carbonate can replace phenolic resin as wood adhesive, and it can also be used to synthesize dimethyl carbonate.

THF is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings, and used in combination. As a reaction solvent, the thickness and brightness of the aluminum layer can be arbitrarily controlled when used in the aluminum electroplating solution. THF itself can be polycondensed (ring-opening and repolymerization initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubbers with abrasion resistance, oil resistance, good low temperature performance and high strength; with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elastic Material.
