Product Description

99% min neopentyl glycol for unsaturated polyester resin 1,CAS:126-30-7 ;99% neopentyl glycol;2,2-Dimethylpropan-1,3-diol;2,2-dimethylpropane-1,3-diol; 2,Appearance:white crystalline solid3,Package:25kg,BIGBAG;2,2-dimetilpropano-1,3-diol;2,2-diméthylpropane-1,3-diol 4,high quality--industrial grade 5.Unsaturated polyester resin English name: Neopentyl glycol, 2, 2-dimethyl-1, 3-propanediol Molecular formula: C5H12O2 Molecular weight: 104.15 Melting point: 124-130°C Boiling point: 210°C Flashing point: 129°C Auto-ignition point: 399°C Relative density: 1.06 g/cm3 (21°C) 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. 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 Index item First Class Appearance White sheet crystal Hydroxide,% 32.0min Ash,% 0.03max Free acid (as acetic acid),% 0.008max Chroma (as Hazen unit) 10max Water,% 0.5max Range of melting point,degree 123-130 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.
