URL: /pvc-phenol-free-ca-zn-stabilizer-ct303tx-slush-molding
Product Summary
CT303TX is a liquid, phenol-free calcium/zinc stabilizer designed for PVC plastisol processing, particularly suited for slush molding applications. With excellent thermal stability and superior demolding performance, it enables consistent production of children's toys, PVC hollow balls, and buoys. Formulated without heavy metals or organotin, it complies with EU REACH, RoHS, and GB 4806 standards for food-contact and toy products. Available in 200kg drums, it supports high-volume manufacturing with minimal defective rates.
Key Features
- Excellent Thermal Stability: Prevents thermal degradation of PVC during processing at 160-200°C, reducing defects.
- Superior Demolding Performance: No mold sticking or product contamination, improving production efficiency.
- Good Initial Colorability: Suitable for light-colored formulations; stable color after thermal aging.
- Environmental Compliance: Contains no lead, cadmium, or organotin; meets REACH, RoHS, and GB 4806.
- Flexible Dosage: 1.5-3.0 phr of PVC paste resin, adjustable per requirements.
