Use to
It can be used as a raw material for synthetic resins, as well as for synthetic aviation lubricating oils, plasticizers, etc.
It can be used as a substitute for glycerol and in the synthesis of dry oils.
It is widely used for the production of polyester and polyurethane foam, as well as the production of alkyd coatings, synthetic lubricants, plasticizers, surfactants, rosin esters and explosives. In addition, it can be directly used as a textile additive and thermal stabilizer for PVC resin. When used in alkyd resin, it can improve the robustness, color, weather resistance, chemical resistance and sealing performance of resin.
It can improve the robustness, corrosion resistance and sealing performance of the resin; and has good stability for hydrolysis, pyrolysis and oxidation.
It is as an organic surface treatment agent in industries such as titanium dioxi
