Dibasic Lead Stearate
Molecular formula: (2 PbO·PbSt)
Properties: It is white, and toxic power with specific gravity of 2.1. It can dissolve in hydrochloric acid and nitric acid, but not in water. As an antioxidant, it has excellent performance of resistance to ultraviolet ray ,cold,and ageing.
Application: Mainly used as the stabilizer of the PVC products ,lubricant,good for the outer lube,advance the PVC soft products’ thermal stability and the PVC boardy products’ tenacity.
Package: Plastic weaved bag, lined with PE bag, and 25Kg weight.
Storage and Transportation: It can be kept in a dry storehouse with good ventilation and separate with humidity, sour gas and sulfureted hydrogen gas in order not to go bad. It can not be transported with food and much attention will be paid to it because it is flammable and toxic .
