Calcium And Zinc Stabilizers
Calcium and zinc stabilizers are usually divided into solid calcium and zinc stabilizers and liquid calcium and zinc stabilizers.
Calcium zinc stabilizer is synthesized by special composite process with calcium salt, zinc salt, lubricant and antioxidant as main components.It can not only replace toxic stabilizers such as Pb, Cd salts and organic tin, but also has good thermal stability, light stability, transparency and coloring power.Practice has proved that in PVC resin products, the processing property is good, the thermal stability is equivalent to lead salt stabilizer, is a good non-toxic stabilizer.
With PVC resin processing process has good dispersion, compatibility, processing liquidity, wide adaptability, excellent surface finish;Excellent thermal stability, small initial hue, no precipitation phenomenon;Free of heavy metals and other toxic ingredients, no vulcanization phenomenon;Congo red test time is long, with excellent electrical insulation, no impurities, with efficient weather resistance;Wide application range, strong practicability, less consumption, with versatility;In white products, whiteness is better than its similar products.
Variety, Specification And Use
According to different uses, CZ-1, CZ-2, CZ-3 compound stabilizer has different varieties: CZ-1, CZ-2, CZ-3, etc., respectively for pipe, profile, pipe fittings, sheet, injection molding, blow molding film, cable material and other plastic products.
CH400, CH401, CH402 calcium zinc compound heat stabilizer is a kind of environmental protection and efficient multi-functional liquid calcium zinc compound heat stabilizer.Excellent thermal stability and transparency, used in PVC products will not produce surface precipitation and migration phenomenon, with heat resistant oil, epoxy methyl ester, epoxy soybean oil and better effect.Suitable for PVC slurry processing, widely used in plastic, plastic coating, dipping PVC processing technology.
This product not only has good compatibility and viscosity control, but also can provide good initial coloring and color retention.The product has proved to be an excellent heat stabilizer.It is soluble, low volatility, small migration and good light resistance. It is suitable for PVC products such as soft pipe, granulation, calendering film, toy, conveyor belt, advertising cloth, wallpaper and so on.
(1) It can replace organic tin stabilizer and lead salt stabilizer to meet the environmental health requirements of non-toxic wires and cables;
(2) with excellent initial whiteness and thermal stability, resistance to vulcanization pollution;
(3) has good lubricity and unique coupling effect, giving the filler good dispersion, enhance the package with resin, improve product performance, reduce mechanical wear, prolong the service life of equipment;
(4) both toughening and promoting melting, plasticizing fluidity is good;
(5) can give PVC mixture good uniform plasticizing and high speed melt fluidity, so that the surface of the product is smooth.
