Product Performance & Features

Our newly developed eco-friendly PVC heat stabilizer is primarily composed of a polymer with a molecular weight of around 3000, which has excellent compatibility with PVC. When combined with other additives as auxiliary materials, it forms a comprehensive processing aid that simultaneously offers heat stability, lubricity, coupling, and toughness.

•Excellent thermal stability, approaching that of organic tin stabilizers and exceeding traditional calcium-zinc stabilizers.

• Due to the presence of hydroxyl, amine, and ester groups in the molecular chain, it can absorb ultraviolet light, thereby exhibiting excellent weather resistance; its weather resistance performance is outstanding.

• Due to the presence of special elements in its molecules, it exhibits good coupling properties with inorganic fillers like calcium carbonate, characterized by a minimal increase in density even when increasing the amount of inorganic material. It can be used as a substitute for active calcium carbonate with regular calcium carbonate.

• Due to its toughening and melt-promoting effects, it offers excellent plasticization, high melt strength, meets high-speed extrusion requirements, improves production efficiency, and reduces production costs.

•Excellent antioxidant properties significantly enhance the aging resistance of the product.

Proprietary ion chelating technology fundamentally resolves the initial discoloration and precipitation phenomena of current solid or liquid calcium-zinc stabilizers at home and abroad.

Sanitation & Environmental Protection - Certified by SGS, meets FDA and ROHS standards, eco-friendly and non-toxic. The product has a sheet-like appearance, causing no dust pollution during use, and is an excellent environmental-friendly item.
