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.
