This series of PVC stabilizers fundamentally solves the core pain points in transparent processing through a unique and innovative collaborative formula system: firstly, its unparalleled compatibility with PVC resin ensures absolute homogeneity of the melt, giving the product a crystal like high transparency and low haze, meeting high-end visual requirements. Secondly, the zinc soap in the system precisely cooperates with auxiliary agents such as β – diketone to provide excellent initial whiteness and long-term anti yellowing ability, effectively suppressing color deterioration caused by heat and light aging during processing and use, and long-lasting protection of the product’s natural color. More importantly, it achieves precise control of thermal stability and lubrication balance, ensuring wide processing windows and smooth operation for precision processes such as rolling and casting, and avoiding defects caused by uneven plasticization or shear overheating. We also provide in-depth customization services, which can adjust stabilizer components and lubrication systems according to your specific resin, process (such as blown film or calendering), and terminal performance requirements. We even provide integrated composite functional packages to help you efficiently and stably produce high-performance transparent products

The production of transparent PVC products, especially films, faces three core challenges, and professional formula calcium zinc stabilizers provide targeted solutions:
Challenge 1: Ultimate Transparency and Low Mist
Requirement: The product must have extremely high optical purity, as any impurities or incompatible substances can cause light scattering and blur the film.
Calcium zinc solution: Using high-purity and structurally designed organic calcium zinc compounds as the main stabilizer. They have excellent compatibility with PVC resin, can be uniformly dispersed in the melt without forming visible crystal points or precipitates, thus ensuring that the product has a crystal like clarity.
Challenge 2: Inhibit initial coloring and long-term yellowing
Requirement: During high-temperature processing and long-term use of the product (especially outdoor exposure), it is necessary to effectively suppress the conjugated polyene structure generated by PVC degradation to prevent the product from turning yellow or brown.
Calcium zinc solution: Through a synergistic stabilization system of calcium/zinc soap and efficient auxiliary stabilizers such as β – diketones and polyols. Zinc soap provides excellent initial coloring prevention ability, while calcium soap and auxiliary stabilizers can absorb HCl for a long time, interrupt the degradation chain reaction, and jointly ensure that the product maintains excellent color stability from processing to the end of its service life.
Challenge 3: Balanced thermal stability and lubricity
Requirement: Transparent film processing is extremely sensitive to thermal history and requires stabilizers to provide precise and stable thermal protection. At the same time, its internal and external lubrication effects must be balanced to ensure uniform plasticization and moderate melt strength, avoiding crystal points, flow lines, or fish eyes caused by shear overheating or poor plasticization.
Calcium Zinc Solution: A customized calcium zinc stabilizer for transparent products, whose formula itself is a precise “lubrication balance system”. It can precisely regulate the plasticization rate and viscosity of PVC melt, ensuring that the material is heated evenly and flows smoothly during extrusion or rolling, ultimately obtaining a smooth surface and uniform thickness film
| **Application Field | Typical Products | Core Performance Requirements | Value of Calcium-Zinc Stabilizer** |
|---|---|---|---|
| Packaging Materials | Food shrink film, candy twist film, transparent packaging boxes | High transparency, high gloss, non-toxicity (compliance with FDA and other food contact regulations), good heat sealability | Provides food-grade safety assurance; excellent transparency and thermal stability support high-speed printing and heat-sealing processes. |
| Agriculture & Building Materials | Agricultural greenhouse film, construction daylighting film/panels | Excellent weather resistance (UV resistance), anti-fogging properties, long-term light transmittance retention | Good compatibility with UV absorbers and anti-fog agents; does not contribute to yellowing, maintaining light transmission over the long term. |
| Consumer Goods & Medical Supplies | Shower curtains, tablecloths, medical infusion bags (non-drug delivery path) | Flexibility, low odor, printability or laminatability, certain antimicrobial requirements | Environmentally friendly and odor-free; good compatibility with plasticizer systems, without affecting product softness or secondary processing. |
| Industrial Protection | Moisture-proof barrier film, equipment protective covers | Good mechanical strength, puncture resistance, heat sealability | Provides processing stability, ensures the base strength of the film, and facilitates subsequent processing. |
