1. PRODUCTS PERFORMANCE:
Pentaerythritol is a kind of organic polyatomic.it is part of white crystal powder solid without poison and odor ,which is stable in air,and without water sucking.melting point 260℃ polymerization,sublimation under pressure reduction,dissolvedslightly in cold water but easliliy in hot water.
2. Package of products:
Each bag of pentaerythritol shall be 25kg,and package of lining plastic film knitting bag shall be adopted.
3. Usea of products:
Pentaerythritol is the main raw material of alkyd resin,oil painting and painting .it also can be used as follow: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.
