Product Characteristics

The product appears as a white powder, composed of long-chain fatty acid salts and anionic layered magnesium-aluminum metal oxides, supplemented with diversified functional materials. It exhibits excellent initial coloration, outstanding long-term heat stability, stable processing performance, and does not exude. It offers the same heat resistance and transparency as organic tin heat stabilizers, with no vulcanization contamination reactions and lasting aging resistance. This product can be used as a 1:1 substitute for organic tin heat stabilizers or thiol-antimony heat stabilizers in the formulation of PVC rigid and flexible transparent products. It is suitable for various processing techniques, including PVC extrusion, calendaring, injection molding, blow molding, rotational molding, and coating. The product has been certified by SGS as compliant with EU REACH regulations.

Technical Parameters

• Appearance: White powder
• Melting Point: 60-68°C
• Heating Loss: ≤0.3%

Application Fields

This product offers high thermal stability, low addition levels, and excellent transparency. It can serve as a 1:1 substitute for organic tin or thiol-antimony heat stabilizers in transparent PVC product formulations, applicable in the following fields:

• PVC transparent sheets
• Calendared films
• IC card substrates
• Food packaging
• Medical packaging
• Medical drainage equipment
• LED light decorations
• Soft wire tubing
• Conduits
• Children's toys
• Shoe materials
• Heat shrink films
• Packaging films
• Stretch films
• Crystal boards
• Soft curtain materials

Note

This product is a mixture of fatty acid salts and magnesium-aluminum layered metal oxides, combined with auxiliary functional additives such as β-diketones and antioxidant systems. It does not have a specific CAS number. Unlike organic tin heat stabilizers, which adhere to national or industry standards specifying effective substance content, the transparent calcium zinc heat stabilizer follows the company’s internal standards, focusing on thermal stability and processing performance, and thus does not specify any effective substance content.
