Calcium zinc stabilizer

Product Description：

Properties and Usage:

Calcium zinc stabilizers are divided into solid calcium zinc stabilizers and liquid calcium zinc stabilizers

Calcium-zinc stabilizer is synthesized using a special composite process with calcium salts, zinc salts, lubricants, antioxidants, etc. as main components. It can not only replace toxic stabilizers such as lead, cadmium salts and organotin, but also has excellent thermal stability, light stability, transparency and tinting power. In PVC resin products, it has good processing performance and its thermal stabilization effect is equivalent to that of lead salt stabilizers. It is a good non-toxic stabilizer.

Powdered calcium zinc stabilizer:

The thermal stability is not as good as that of lead salt, and it has certain lubricity, poor transparency, and easy blooming. In order to improve its stability and transparency, antioxidants such as hindered phenols, polyols, phosphites and β-diketones are often added to improve it.

The two major systems of calcium zinc stabilizers are mainly divided into hydrotalcite system and zeolite system.

Liquid calcium zinc stabilizer:

Appearance is mainly light yellow oily liquid. There is not much difference in the stability between powder and liquid. Liquid calcium zinc stabilizers usually have greater solubility and good dispersion in PVC resin powder, and their impact on transparency is much smaller than that of powder stabilizers. However, liquid stabilizers have a greater risk of precipitation. A suitable solvent needs to be selected.

It is an environmentally friendly, high-efficiency, multifunctional liquid calcium-zinc composite heat stabilizer. It has excellent thermal stability and transparency. When used in PVC products, surface precipitation and migration will not occur. It has better effects when used in combination with heat-resistant oil, epoxy methyl ester, and epoxy soybean oil. It is suitable for PVC slurry processing and is widely used in PVC processing processes such as slush molding, coating, and dipping.

This product not only has good compatibility and viscosity control, but also provides good initial coloring and color retention. This product has proven to be an excellent heat stabilizer. It has good compatibility, low volatility, small migration, and good light resistance. It is suitable for PVC product industries such as soft pipes, granulation, calendered films, toys, conveyor belts, advertising cloths, and wallpapers.

1. Environmental protection: Calcium zinc stabilizer does not contain harmful substances, can effectively replace traditional toxic stabilizers, and meets environmental protection and health requirements. Can replace organotin stabilizer and lead salt stabilizer

2. Excellent thermal stability: Compared with traditional lead salt stabilizers, calcium zinc stabilizers exhibit equivalent thermal stability properties and can effectively prevent the degradation of PVC products at high temperatures.

3. Enhanced physical properties: Provides good lubricity and unique coupling effect, improves filler dispersion, enhances resin wrapping, improves product performance, reduces mechanical wear, and extends equipment service life.

4. Improved processing performance: Good plasticizing fluidity and uniform plasticizing characteristics make the PVC mixture easy to process and ensure a smooth and flawless surface of the product.

5. Excellent initial whiteness and sulfur resistance: It has excellent initial whiteness and can resist sulfur pollution and maintain the beauty of the product.
