Application of calcium zinc stabilizer in PVC hard products

  Calcium zinc stabilizer is widely used in the plastic industry as a stabilizer for PVC pipe.For a long time,lead salt and barium,cadmium soap stabilizer has been the world PVC heat stabilizer market because of its low price and excellent performance.Although lead salt and cadmium heat stabilizer used in traditional PVC processing has excellent heat stability performance,its harm to the body and the environment exceeds its advantage.So the future market trend will definitely be calcium zinc stabilizer.
  Calcium zinc stabilizer can replace lead salt series,other calcium zinc and organotin stabilizer to meet the environmental hygiene requirements of wire and cable;Excellent initial whiteness and thermal stability,resistance to vulcanization pollution;With good lubricity and coupling effect,give the filler good dispersion,improve and resin encapsulation,improve product performance,reduce mechanical wear,prolong the service life of equipment;Both toughening and promoting melting,good plasticizing fluidity;PVC mixture can be given good uniform plasticizing and high-speed melting flow,so that the surface of products smooth,enhance the mechanical properties of products.
  From the use effect,there is a certain gap between the performance of organometallic soap and that of lead salt.Organotin heat stabilizer is also a very effective heat stabilizer,its dosage is small,can make transparent products to maintain a high transparency,but its potential toxicity to human central nervous system has attracted great attention.In recent years,by optimizing the advantages of all kinds of stabilizer,the stabilizer manufacturers have studied the use of calcium and zinc composite stabilizer to replace lead salt and other products,which has become the mainstream trend of the development of PVC thermal stabilizer.
