    AI Overview
    PVC heat stabilizer powder is an essential additive, often Calcium-Zinc (Ca-Zn) based, used to prevent degradation, discolouration, and brittleness in polyvinyl chloride (PVC) products during high-temperature processing and environmental exposure. These white or light yellow powders improve thermal stability, mechanical properties, and long-term durability for applications like pipes, profiles, and wires. 
    Key Types & Characteristics 
    • Calcium-Zinc (Ca-Zn) Powder: A popular, non-toxic, and eco-friendly option frequently used for rigid and flexible PVC, offering excellent early color hold.
    • Lead-Free Stabilizers: Modern powder stabilizers focus on being heavy-metal-free to comply with environmental standards.
    • One-Pack Stabilizers: These combine multiple additives (lubricants, antioxidants) into a single powder formula, simplifying the manufacturing process, particularly for pipes and cables. 
    Core Functions 
    • Thermal Protection: Prevents PVC from decomposing due to heat during manufacturing.
    • Durability Enhancement: Maintains mechanical strength and prevents cracking.
    • Aesthetics: Protects against yellowing and discoloration. 
    Common Applications 
    • Profiles & Pipes: Used extensively in window frames, door profiles, and piping systems.
    • Wires & Cables: Provides the necessary heat resistance for insulation materials.
    • Films & Sheets: Often used in transparent or flexible, high-gloss PVC products.
