1. Character :
It is organic polyol, non-toxic, odorlessness, white crystal powdery solid, stable in the air, sublimating under the reduced pressure, little soluble in cold water and soluble in hot water.
2. Package :
25kg/bag, liner plastic woven bag.
3. Usage :
The pentaerythritol is raw material of alkyd resin, paint and coating used in making cold-hot resistant and non-toxic plasticizer, lubricant additive, emulsifier, petroleum antifreeze, polyvinyl-chloride stabilizer, chlorinated polyether, refractory paint, glossy black products. Becoming tetranitro pentaerythritol responsed with the nitric acid and is high explosive.
