Lead based stabilizer, also called dust-free lead complex stabilizer. heating and mixing by various lead stabilizer, auxiliary-stabilizer and internal & external lubricants. It is flake, granule or powder form.
The basic composition of lead based stabilizer main-auxiliary stabilizer and internal & external lubricants, In order to cut the cost, the lead based stabilizer often add some filler. Existing experiments show that a small amount of filler will not affect the performance of lead based stabilizer, but in recent years, some undesirable factories add too much filler in lead based stabilizer to cut the cost.
Lead based stabilizer
The main stabilizer of lead based stabilizer select from single lead stabilizer such as tri-basic lead sulfate, di-basic lead phosphite, di-basic lead phthalate and organic lead stabilizer. The lubricant of lead based stabilizer include esters, wax, fatty acid, etc. Metallic soap is also a composition of lead based stabilizer because of its stability and lubricity. The most important is the synergistic effect of all kinds of stabilizer and lubricant when producing lead based stabilizer.
