Highly effective hydrotalcite-based heat stabilizer for polyvinyl chloride (PVC) compounds.
Halogen-free and heavy-metal-free formulation, supporting sustainable and regulatory-compliant PVC processing.
Excellent long-term thermal stability with low color development during extrusion and calendering.
Good compatibility with common PVC plasticizers, fillers, and co-stabilizers such as calcium/zinc soaps.
Enhances melt homogeneity and reduces plate-out in high-output PVC production lines.
Rigid PVC profiles for window frames and building façades.
PVC pipes and fittings used in potable water and drainage systems.
Flexible PVC flooring and wall coverings requiring low smoke and zero heavy metals.
Medical-grade PVC tubing and packaging where regulatory compliance is critical.
Electrical insulation sheathing and cable jacketing materials.
