Product Performance and 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. Combined with other additives as auxiliary materials, it forms a comprehensive processing aid that offers heat stability, lubricity, coupling, and toughness.

•Excellent thermal stability, comparable to organic tin stabilizers and superior to 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 filler. 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 the requirements for high-speed extrusion, improves production efficiency, and reduces production costs.

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

Exclusive ion chelating technology fundamentally resolves the initial discoloration and precipitation phenomena of solid or liquid calcium and zinc stabilizers at present both domestically and internationally.

Health & Environmental Protection: SGS-certified, compliant with FDA and ROHS standards, this is an environmentally friendly and non-toxic product. It comes in sheet form, producing no dust pollution during use, and is a superior eco-friendly product.
