Purpose

1.It is used in the manufacture of pentaerythritol tetranitrate dynamite and alkyd resin, as well as thermal stabilizer and plasticizer. It is used in the production of alkyd resin, synthetic advanced lubricant, plasticizer, surfactant, medicine and explosives.

2.It's an important polyol compound. It is widely used in the production of alkyd resin, flame retardant coating, polyurethane and dry oil. Is also the synthesis of plasticizer, flame retardant, surface active agent, emulsifying agent, pesticides, antioxidants, senior lubricating oil, pentaerythritol ester, pentaerythritol polyether and polyester, PENT explosives and the main raw material of chlorinated polyether and so on.

3.It is used as the raw material for the production of rosin ester in varnish, paint and ink, and can be used as flame retardant, dry oil and aviation lubricants.
