Tin stabilizer is a high-performance, environmentally friendly heat stabilizer formulated primarily with modified organotin, compounded with co-stabilizers, lubricants, and antioxidants. It serves as a complete drop-in replacement for traditional lead-based stabilizers and conventional metal soap stabilizers, making it suitable for the production of all grades of high-quality PVC products. The product is SGS-tested, with no heavy metal migration, and complies with food contact safety standards. During high-temperature PVC processing, it effectively inhibits material decomposition over extended periods—preventing yellowing immediately after production as well as delaying discoloration and aging during long-term service. In addition, it improves processing fluidity, enhances the light transmittance of transparent finished products, and extends their service life.

Product Advantages

Clear, beautiful, UV-stable, and aging-resistant.

High compatibility with PVC resin, producing transparent and crystal-clear finished products free of white haze. No blooming or whitening occurs during long-term storage. Resists yellowing even under high-temperature high-speed processing, thick-wall part manufacturing and recycled PVC compounding. Features excellent UV resistance for outdoor applications, effectively preventing cracking and gloss loss. Widely applicable to PVC pipes, sheets and packaging containers.

Safe and eco-friendly, suitable for all high-standard products.

Free of harmful heavy metals such as lead and cadmium, no sulfide contamination, and low migration. It complies with environmental testing standards for food-contact materials, medical devices, maternal and infant products, and export commodities.

Easy processing and improved production efficiency

Formulated with built-in lubricants to deliver smooth melt flow of plastics, with a wide applicable processing temperature range. It prevents mold sticking and minimizes equipment fouling during long-term continuous production, eliminating frequent shutdowns for cleaning and reducing defective rates. Compatible with multiple processes including extrusion and injection molding.

Applications

Tin stabilizers feature a wide range of application scenarios, covering all kinds of high-end PVC and polymer product fields.For rigid products: suitable for transparent PVC bottles, boards, sheets, special-shaped profiles, pipes and fittings, etc.For flexible products: compatible with food-grade hoses, medical catheters, infusion bags, sealing strips, premium artificial leather and other items.They can also be used in high-end eco-friendly applications such as food packaging films and children’s plastic toys.
