What are the advantages of PVC stabilizer

Advantages: the same as a heat stabilizer, a lead compound PVC material without compromising the excellent electrical properties,
low water absorption and outdoor weatherability. Disadvantages: Toxic; would cross contamination; generate lead chloride, forming
streaks on finished products; than Stabilizers for pipe  significant; immediately so often lead stabilizers in PVC products become opaque, and soon after
continuous heat discoloration. With the ban of lead, "Twelve Five" period while the proportion of lead stabilizers in PVC heat
stabilizers will be reduced year by year. Metal soap stabilizer monomer salt (acid salts): zinc stearate, barium stearate, calcium
stearate, lead stearate, cadmium stearate Metal soap  Aluminum hydroxide salt composite stabilizer: calcium zinc stabilizers, barium zinc stabilizer, barium cadmium stabilizers, barium cadmium
zinc stabilizer organic tin stabilizer
Advantages: PVC stabilizer organotin heat stabilizers for the most efficient, transparent and non-toxic products in the most widely
used of a class, its outstanding advantages: good thermal stability, transparency, and most of the non-toxic.
 Disadvantages: PVC stabilizer high prices, no lubrication.
 Most of the liquid organic tin, only a few PVC plasticizer  solid. May be used alone, often with a metal soap. Rare Stabilizer: no lubrication,
should join with the lubricant, the current production of rare earth compound stabilizer is rare, heat stabilizers and lubricants
compound formed, the amount is usually 4-6 copies. Another class of organic antimony stabilizer, a liquid stabilizer.
