Product Features
PVC Special Zeolite is mainly used in the production and processing of PVC (Polyvinyl Chloride), with the main purpose of improving the performance and stability of PVC. Selection is generally based on its adsorption capacity, ion exchange performance, and thermal stability.
Applications
1.Heat Stabilizer
Zeolite acts as a heat stabilizer for PVC, absorbing hydrogen chloride (HCl) released during PVC processing, delaying thermal degradation and improving thermal stability.
2.Adsorbent
The porous structure of zeolite adsorbs small-molecule impurities in PVC (such as moisture, volatile organic compounds, etc.), improving purity and processability.
3.Antistatic Agent
In certain PVC products, zeolite provides antistatic effects, reducing static buildup and enhancing product safety.
4.Filler
Zeolite can be used as a filler in PVC to improve mechanical properties (hardness, strength, etc.) and lower production costs.
5.Environmental Protection
Zeolite adsorbs harmful gases (chlorine, HCl, etc.) generated during PVC production, reducing environmental pollution.
6.Catalyst Support
In some PVC modification or synthesis processes, zeolite serves as a catalyst support to improve reaction efficiency.

FAQ
Q: What is the primary function of Zeolite in PVC processing?
A: It acts as a non-toxic co-stabilizer and water scavenger. It absorbs HCl released during degradation and removes trace moisture, preventing "fish eyes" and improving thermal stability.
Q: Is your product compliant with food contact and medical regulations?
A: Yes. Our PVC-grade Zeolites are fully compliant with FDA (USA), EU 10/2011, and REACH standards, making them safe for food packaging and medical tubing.
Q: How does the particle size affect PVC product transparency?
A: We offer nano-sized grades specifically designed for transparent applications. Smaller particles minimize light scattering, ensuring high clarity in films and sheets.
Q: How should PVC Zeolite be stored to maintain its water-scavenging efficiency?
A: It must be kept in a strictly dry environment with sealed packaging. Exposure to humidity before processing can saturate its pores, reducing its effectiveness as a stabilizer.
Q: Is your manufacturing process environmentally sustainable?
A: Absolutely. Our production uses eco-friendly methods with zero heavy metal discharge, aligning with global green manufacturing trends and sustainability goals.
Q: Can you send samples?
A: Certainly. We provide free samples for quality inspection.
