Stabilizers are additives crucial for preventing PVC degradation caused by heat and light exposure. They typically contain metal elements like barium, cadmium, or zinc that react with released hydrochloric acid to inhibit further degradation. Stabilizers are essential in PVC formulations for maintaining product integrity and extending its lifespan in various applications.
1. Lead Stabilizers: Effective for applications requiring long-term heat stability, like cables and pipes. They are cost-effective but can pose toxicity concerns.
2. Tin Stabilizers: Known for excellent clarity in transparent products like tubing and medical devices. They are versatile but can cause sulfide staining when used with lead stabilizers.
3. Calcium Zinc Stabilizers: Non-toxic and used in various applications where clarity and stability are essential, such as profiles and fittings. They offer good weatherability and are environmentally friendly.
4. Mixed Metal Stabilizers: These include other stabilizer used for specific application to provide the effective results with premium quality
