Properties: Neopentyl glycol is white crystal solid substance without bad smell. It's hygroscopic and at the normal temperature, it is mutually dissolved with water, low level alcohol, and low level ketone and arene compound.
Usage: Neopentyl glycol has a wide range of functions, among which the main role is to produce oil freeze alkyd resin, unsaturated polyester resin, flexible soft foam of polyurethane, insulated materials, print inks, synthetic plasticizers, aircraft lubricant agent and the like.
Packing: solid product: plastic woven bag with PE film inside, 25kg/bag
Liquid product: zinc plating iron drum, 25kg/drum
Storage: Since the relative humidity of neopentyl glycol is high, it should be stored far from the moisture and fire.
Quality standard: HG/T2309-92
