Product type
Stabilizers are additives used in the production of polymers and plastics to enhance their stability and longevity. They work by preventing degradation caused by heat, light, and environmental factors. Commonly made from various chemical compounds, including metal salts and organic substances, stabilizers are essential for maintaining the integrity of plastic materials during processing and throughout their lifecycle.
| Chemical composition | Metallic salts, organic compounds, or phosphites |
| Form | Powder, granules, or liquid |
| Typical concentration | 0.1% to 5% by weight |
| Processing temperature range | Up to 250°C |
| Compatibility | Compatible with various polymer types, including PVC, PE, and PP |
When selecting stabilizers, buyers should consider the specific type of polymer they are working with and the environmental conditions the final product will face. It is important to specify the desired concentration, form, and any regulatory certifications required for the application. Quantities may vary based on production needs, so providing an estimate can help suppliers offer suitable options.
