Frequently Asked Questions

Get answers to common inquiries about our PVC stabilizers.

What is the difference between lead-based and calcium-zinc stabilizers?

Lead-based stabilizers offer excellent thermal stability and cost efficiency, commonly used in construction applications. Calcium-zinc stabilizers are non-toxic and environmentally friendly, ideal for potable water, medical, and consumer goods where regulatory compliance is critical.

Are your products compliant with international regulations?

Yes. Our calcium-zinc stabilizers comply with RoHS, REACH, and other global environmental standards. Lead stabilizers are manufactured under strict controls and are suitable for applications where permitted by local regulations.

Can I get technical support for formulation optimization?

Absolutely. Our technical team provides comprehensive support including dosage recommendations, compatibility testing, and troubleshooting for processing issues.

What packaging options are available?

We offer 20kg or 25kg multi-layer paper bags with inner plastic liners. Custom packaging solutions are available upon request for bulk orders.

How do I choose the right stabilizer for my application?

Selection depends on your PVC formulation, processing method (extrusion, injection, calendering), end-use requirements (color, clarity, durability), and regulatory needs. Contact our team for a tailored recommendation.
