Calcium Zinc Stabilizer Enhances Product Performance
The calcium-zinc stabilizer has been widely used for its non-toxic, inexpensive, good lubricity and the combination of long-term thermal stability of calcium soaps with good initial coloring of zinc soaps. However, due to thermal stability is not high, for a long time for the thermal stability of the low requirements of PVC soft products or as leaded, cadmium, Ca-Zn Stabilizer barium thermal stabilizer of the auxiliary heat stable components used.
In order to improve the thermal stability of calcium-zinc stabilizer, the application range was enlarged. Since the 1960s, people on the basis of calcium and zinc composite, Ca-Zn Stabilizer the introduction of a variety of auxiliary components, including β one or two ketone, phosphite, epoxy compounds, Ca-Zn Stabilizer polyols and antioxidants.
The mechanism of calcium-zinc stabilizer is: Zn soap as the main stabilizer, with the replacement of active chlorine and the absorption of HCL, the subsequent formation of the metal chloride is Lewis acid, can promote the removal of HCI reaction.
Calcium Zinc stabilizer is widely used in PVC products processing and production, the production of PVC products have a lot of excellent performance. Ca-Zn Stabilizer Here is a brief introduction to the specific role of calcium zinc stabilizer:
1, can replace the organic tin stabilizer and lead salt stabilizer, meet the non-toxic wire and cable environmental hygiene requirements;
2, with excellent initial whiteness and thermal stability, resistance to sulfide pollution;
3, with good lubrication and unique coupling effect, to give a good dispersion of fillers, enhance and resin package, improve product performance, reduce mechanical wear, Ca-Zn Stabilizer prolong the service life of equipment;
4, both toughening and promoting melting, plastic fluidity good;
5, the PVC mixture can be given a good uniform plasticizing and high-speed melt fluidity, so that the surface of the product smooth.
CH400, CH401, CH402 calcium Zinc stabilizer is a kind of environmental protection high efficiency multifunctional liquid calcium zinc compound heat stabilizer. Good thermal stability and transparency, for PVC products will not produce surface precipitation and migration phenomenon, Ca-Zn Stabilizer with the heat-resistant oil, epoxy methyl ester, epoxidized soybean oil and the effect is better. Suitable for PVC slurry processing, widely used in plastic, plastic, impregnation and other PVC processing technology.
Calcium-Zinc stabilizers not only have good compatibility and control of viscosity, Ca-Zn Stabilizer but also provide good initial coloring and color preserving.
Calcium-Zinc stabilizer is proved to be an excellent heat stabilizer. Good solubility, low volatility, small mobility, good light resistance, Ca-Zn Stabilizer suitable for soft pipe, granulation, calendering film, toys, conveyor belt, advertising cloth, wallpaper and other PVC products industry.
