Solid powder Ca/Zn PVC stabilizer promotes environmental protection

📌 Product Overview

Solid powder Ca/Zn PVC stabilizer are environmentally friendly, non-toxic powders with organic calcium-zinc salts at their core (such as calcium/zinc stearate and calcium/zinc acetylacetonate), combined with highly effective auxiliary agents (β-diketones, pentaerythritol, antioxidants) to optimize synergistic effects. Their features include:

Non-toxic and environmentally friendly: Free from heavy metals such as lead and cadmium, compliant with the EU RoHS Directive, and certified by SGS.  

High stability: Balances thermal stability and lubricity, inhibits initial discoloration of PVC, and extends long-term thermal aging lifespan.  

Wide applicability: Suitable for soft/hard PVC, transparent films, foam materials, etc., and can replace traditional lead salt stabilizers.
