In PVC foaming processing, it can effectively inhibit the thermal degradation of the PVC matrix, while precisely regulating the foaming nucleation and bubble growth
rate, avoiding problems such as uneven cell distribution, collapse and yellowing. It
has excellent compatibility with PVC resin and foaming agents, does not affect the
foaming ratio, and ensures uniform density and smooth surface of the products.
Packing: 25kg/ bag
Storage: Conventional storage
Processing: Valid for 2 years
Note: Store in cool, dry warehouse, avoid rain, moisture. When stored, it must be away from fire and heat sources, avoid exposure to sunlight, and prohibit direct contact with acid and alkali or mixing.
1.Green and Environmentally Friendly:
Contains no heavy metal elements (such as lead or cadmium), meeting the latest environmental standards of various countries (such as the EU'S ROHS Directive, REACH Regulation, etc.).
2.Resistance to sulfidation contamination: In the processing and application of PVC foam products (especially PVC foam door and window profiles, decorative profiles), products using traditional composite lead heat stabilizers are extremely prone to blackening and discoloration on the surface when exposed to sulfur-containing substances in the air or tin-containing additives.
3.Superior system compatibility:
This formulation can directly replace lead salts and organic tin stabilizers. Unlike traditional lead-based heat stabilizers that may cause cross-contamination and product discoloration when converted to organic tin stabilizers, and calcium-zinc stabilizers that cannot be freely switched or blended, this system ensures seamless substitution.
CZ75 calcium-zinc stabilizer has excellent anti-sulfidation performance, and its chemical properties are stable. It will not react with sulfur and tin elements, effectively avoiding the sulfidation blackening problem of products. It ensures that the surface of PVC foam products remains white and bright for a long time, and the appearance quality is stable and reliable.
4.Excellent Product Performance CZ75 can provide PVC blends with excellent uniform plasticization effect and high-speed melt flow performance, making the PVC melt fully plasticized and evenly flowing during processing, and the surface finish of the final foam product is significantly improved, showing a bright and delicate visual effect. The product has high purity and no visible impurities, which can effectively reduce the defect rate of products such as spots and lines. At the same time, it has superior weather resistance, and the products processed are not easy to age, fade or crack under the long-term exposure of sunlight and rain. It has a wide range of applications, suitable for various PVC foam processing processes such as extrusion and calendering, and has low dosage requirements, which can reduce the production cost of customers on the premise of ensuring product quality. In white PVC foam products, it can achieve higher whiteness than similar products, meeting the high aesthetic requirements of customers for white products.
5.High cost-performance ratio:
Exhibits excellent lubricity and unique coupling effects, enhancing product performance, reducing mechanical wear, and prolonging equipment service life. Due to its balanced lubrication properties, it is less prone to precipitation. The production cycle is prolonged.
