Application:
PU industry
used in the production of polyester and polyurethane foams, it is also used in the manufacture of alkyd coatings, synthetic lubricants, plasticizers, surfactants, fiber processing agents, rosin esters and explosives. It is also directly used as a textile auxiliary agent and heat stabilizer of PVC resin. It can be used in alkyd resin to improve the firmness, color tone, weather resistance, chemical resistance and sealing performance of the resin. Polyvinyl alcohol and polyoxymethylene resin can be dissolved in polymer substances. Therefore, it can be used as a plasticizer for these resins.
