Petrochemical Additives
PVC Terminator (Polymerization Terminator)
This product is used in the PVC polymerization process to rapidly eliminate free radicals, terminate the polymerization reaction, and improve PVC resin quality. The formula adds a variety of imported high-efficiency antioxidants, which not only terminate the polymerization reaction quickly but also significantly improve the thermal-aging whiteness of PVC products, effectively improve the intrinsic quality of the resin, and ensure that the resin products do not yellow during downstream processing.

PVC Anti-fouling Agent (Kettle Release Agent)
This anti-fouling agent is used in the PVC polymerization process to protect the inner wall of the polymerization kettle, with excellent anti-fouling effect. After spraying, it forms a protective layer on the stainless steel surface that prevents materials from sticking to the kettle, extends the cleaning cycle, improves equipment utilization, and enhances PVC resin quality.

PVC Heat Stabilizer
This PVC heat stabilizer is a "multi-function-in-one" product. Based on the actual requirements of China's PVC industry, it adopts innovative technology and a specific process to form a fairly stable emulsified heat stabilizer. Its features: high efficiency, safety, non-toxicity, no pollution, and easy dilution; it disperses quickly when added into the polymerization kettle, with fine and uniform particle size, allowing it to be fully and rapidly embedded into the pores of PVC particles. Therefore, it can effectively increase the termination speed of the polymerization reaction and improve the aging-whiteness index that characterizes the thermal stability of PVC resin, as well as deliver better initial discoloration resistance during PVC product processing. The heat stabilizer not only meets user quality requirements but is also convenient to use.

2-(2′-Hydroxy-3′,5′-dicumenylphenyl)benzotriazole
UV absorber ZOORY-UV234 has excellent heat stability and compatibility, and is especially effective for resins requiring high-temperature processing, such as polycarbonate, polyester, polyoxymethylene, polyamide, polyphenylene sulfide, polyphenylene oxide, thermoplastic polyurethane, and polyurethane fibers. Meanwhile, it features low volatility, strong light absorption, and good compatibility with different substrates, so it is especially suitable for high-surface-area products such as films and fibers. When used in coatings, it is recommended for automotive coatings, coil coatings, and powder coatings; combined with hindered amine light stabilizers (HALS), the effect is more ideal. The combined formula provides better protection for coatings, including preventing discoloration, loss of gloss, cracking, blistering, and detachment from the substrate.

Tetraethyl 2,2′-(1,4-phenylenedimethylene)dioxomalonate
Excellent resistance to metal-ion effects: Other types of UV absorbers may yellow under the influence of metal ions. ZOORY-N2000 has excellent resistance to metal-ion yellowing, providing the resin with superior anti-yellowing performance. Metal-ion yellowing effects on different UV absorbers (example: effect of nickel acetate): 1# Triazine UV absorber UV1164; 2# Triazole UV absorber UV-P; 3# Triazole UV absorber UV-234; 4# Benzophenone UV absorber UV-531; 5# ZOORY-N2000. Introduction: UV absorber ZOORY-N2000 is a white, low-color UV absorber with very strong UV absorption at 320 nm. ZOORY-N2000 has excellent resistance to metal-ion yellowing and to harsh climate conditions, so it is especially suitable for resin systems with strict requirements for transparency and color. It provides excellent color stability to resins, especially suitable for transparent materials such as PC, PET, PMMA, and PS, and is especially suitable for products with special high-performance requirements such as automotive lighting.
