Products Introduction:

 

Propylene glycol can be used as raw material for unsaturated polyester resin, epoxy resin, plasticizers, surfactants and PU resin, mainly used for paint, coating and plastic industries.
In cosmetics, can be used as a wetting agent and emollient, because of good viscosity and hygroscopicity.

In daily chemical is an important solvent.

It used as an antifreeze, also an important material for Tobacco Humectant.
