Use to
It can be used as a raw material for syntheticresins, as well as for synthetic aviation lubricating oils, plasticizers, etc.
It can be used as a substitute for glycerol andin the synthesis of dry oils.
It is widely used for the production of polyesterand polyurethane foam, as well as the production of alkyd coatings, syntheticlubricants, 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 inindustries such as titanium dioxide.
