Usage:
<1>Pentaerythritol is the main raw material of alkyd resin,oil painting and printing.It also can be used as follows:manufacturing plastifiers that of hot and cold resistance and without poison,additive agent of lubricant, emulsifying agent,petroleum anti-freezing agent,stabilizing agent of polyvinyl chloride, chlorinated polythether, fire retardant,fire resistance painting and printing ink and the like.Tetranotro-penraerythritol,which is a kind of high expolsive,produced after the chemical reaction with nitric acid.
<2>Di-PE,as an important fine-chemical intermediate,it is mainly used in coating industry,polyether,alkyd resin and photosensitive resin film.Its low aliphatic ester is used as PVC.plasticizer in hi-temp insulating material.Its high aliphatic ester is used in aviation.
