use | used in the manufacture of polyester fibers, polyester appliances, unsaturated polyester resins, polyester glazes, polyurethane foams, and for the production of lubricants and hydraulic fluids. In addition to the synthesis of PETG, it is also used as an intermediate for the synthesis of saturated and unsaturated polyesters for coatings, inks, adhesives, insulating materials and some special purposes. The product produced by 1,4-CHDM has a very high glass transition temperature. It has good hardness and certain flexibility. The obtained light-colored resin has excellent thermal stability and good solubility and weather resistance. Used to produce polyester fiber, etc. |
production method | methanol solution of dimethyl terephthalate is hydrogenated and reduced under pressure to obtain the product. |
