Some major effects of barium zinc PVC stabilizer

Stabilizer introduced in the benzene ring is a new attempt. Improve the

relative molecular mass of organic tin stabilizer , but also a new

research trends. Main ways : organic tin stabilizer own high molecular

weight , the formation of polymeric organic tin ; unsaturated organic tin

compounds with the appropriate monomers to improve its relative molecular

mass ; middle with bifunctional compounds and organotin organotin body

molecules to form a molecule containing a plurality of tin atoms to

improve their relative molecular mass and the like. Avoid small relative

molecular mass and volatile due to become odorless "clean " type organotin

stabilizers . Their constituents , except barium soap , zinc soap , there

phosphites and coloring preventing agent. The new  high performance

phosphite emerging, prompted the rapid development WSD PVC flame retardant  of such stabilizers .

Especially in recent years β- diketones as preventing the use of initial

coloring agent to make the performance of barium zinc stabilizer class

more perfect. The main advantages : superior weatherability barium -

cadmium stabilizers; improved cold can reduce the amount of phosphate type

auxiliary plasticizer .
Barium zinc stabilizer is mainly used for rolling and plasticized PVC

plastisol processing , but also from the product into powder and liquid

form . Can be compared with liquid barium cadmium stabilizers thermal

stability of liquid barium zinc stabilizer compatibility with commonly

used plasticizer in PVC as well as a stable and WSD zinc stearate  transparent terms . Also

recently appeared on the market a new barium zinc products , the product

tasteless, non fouling phenomena in the processing of the plasticized PVC

, and exhibits excellent self- lubricating effect . Barium zinc stabilizer

slightly inferior in light stability , can be compensated with an epoxy

plasticizer and an ultraviolet absorber. Also WSD Polyethylene wax  barium metal, although a

very small solubility in water , but if access to the gastrointestinal

tract , the stomach acid to increase its solubility, greater toxicity, and

therefore is limited in recent years in many applications.
