Application
1. Used as the raw material of synthetic resin, and also used for synthetic aviation lubricating oil, plasticizer, etc.
2. Used as the glycerine substitute, and also used for the synthesis of drying oil.
3. Widely used in the production of polyester and polyurethane foam, also used in the manufacture of alkyd coatings, synthetic lubricants, plasticizer, surfactant, rosin ester and explosives. Also used directly as textile auxiliary agent and PVC resin thermal stabilizer. And used in alkyd resin application, it can improve the resin's firmness, color, weather resistance, chemical resistance, and sealing properties.
4. Have the advantages of improving the firmness, corrosion resistance and sealing performance of resin, and have good stability to hydrolysis, pyrolysis and oxidation.
