Abstract

Calcium zinc heat stabilizers are superior to calcium zinc composite stabilizers and metal soaps, three times that of lead salts and four times that of Ba/Zn composite stabilizers.

Detailed explanation of the effect of calcium zinc composite stabilizer

(1) Excellent thermal stability performance

Calcium zinc heat stabilizers are superior to calcium zinc composite stabilizers and metal soaps, three times that of lead salts and four times that of Ba/Zn composite stabilizers. It can be compounded to become non-toxic and safe, and can also partially replace organotin stabilizers and be widely used. Widely used in PVC pipes, wires and cables, etc.

(2) Coupling effect

Calcium zinc composite stabilizer has excellent coupling effect, and compared with lead salt, it has good compatibility with PVC, which is beneficial for improving the strength of PVC plastic door and window profiles. The weld strength of PVC profiles processed with rare earth stabilizers is higher than that of PVC profiles processed with lead salt stabilizers, and the raw material price is also higher.

(3) Toughening effect

The good compatibility with calcium zinc heat stabilizer resin and toughening agent CPE, as well as the coupling effect with CaCO3, result in uniform plasticization of PVC resin during processing, low plasticization temperature, and good impact resistance of profiles.

Stabilization mechanism of PVC calcium-zinc stabilizers

The presence of activating groups on the PVC chain usually makes it susceptible to degradation reactions by de-HCl above 100 °C.

Precautions for the use of PVC stabilizer and calcium zinc stabilizer

Calcium zinc stabilizer is a commonly used PVC stabilizer with non-toxic and environmentally friendly characteristics.

Application scope and characteristics of calcium zinc stabilizer in PVC

The product complies with EU ROHS, PAHS, REACH standards and does not contain highly concerned substances such as phthalates, PFOA, and PFOS.
