Liquid Calcium Zinc PVC Stabilizer

Product Overview

Liquid Calcium Zinc Stabilizer is a non-toxic, eco-friendly organometallic heat stabilizer specially developed for flexible and semi-rigid PVC processing. Formulated with organic calcium salts, organic zinc salts, high-efficiency antioxidants, chelating agents and lubricants through precise compounding, it appears as a light yellow transparent oily liquid, completely free of heavy metals like lead, cadmium and tin. It fully complies with global environmental and food contact regulations, and is an ideal sustainable alternative to traditional barium-zinc, lead-based and organotin stabilizers for modern PVC manufacturers.

Key Specifications

Core Features

1. ‌Full Non-Toxic & Regulatory Compliance‌: Heavy metal-free formulation, fully meets EU REACH, RoHS, FDA food contact and GB food safety standards, no toxic heavy metal precipitation risk for end products.

2. ‌Excellent Heat Stability Performance‌: Delivers balanced initial-color whiteness and long-term thermal stability, effectively suppresses PVC yellowing and degradation during processing, no sudden blackening phenomenon.

3. ‌Perfect System Compatibility‌: Shows excellent miscibility with PVC paste resin, plasticizers and other liquid additives, no stratification, no precipitation, no blooming on finished product surface after long-term storage.

4. ‌Good Transparency & Processability‌: Low haze performance, helps flexible PVC products achieve clear and uniform appearance, while providing moderate lubricity to reduce processing torque and improve melt flow.

5. ‌High Operational Convenience‌: Liquid form can be directly added into the mixing system at room temperature, no pre-melting required, no dust pollution on production site, easy for automatic metering feeding.

Recommended Applications

· PVC gloves, PVC slush toys, wallpaper and artificial leather coating

· PVC wire and cable, flexible transparent hoses, door sealing strips

· PVC food packaging films, pharmaceutical packaging materials and medical-grade soft PVC products

· PVC calendered flexible films, extrusion soft profiles and PVC paste processing scenarios

Suggested Dosage

For PVC paste resin processing scenarios such as gloves and slush toys, the recommended addition level is 1.0 - 1.5 phr per 100 parts of PVC resin. For calendering and extrusion flexible PVC products, the suggested dosage is 2.0 - 3.0 phr. Customers can adjust the loading amount according to their specific formulation system and processing technology.
