PVC window and door profile-specific calcium-zinc stabilizer Excellent initial coloration Long-term heat stability and anti-blackening propertyPVC window and door profile-specific calcium-zinc stabilizer is a high-performance, environmentally friendly functional additive specially developed for PVC window and door profiles, aiming to solve the key pain points of poor initial color, easy blackening and insufficient long-term heat stability during the processing and use of PVC profiles. With excellent initial coloration performance, it can effectively inhibit the initial coloring and yellowing of PVC materials during high-temperature extrusion, ensuring that the surface of PVC window and door profiles is bright, uniform and consistent in color, without color difference or yellow spots, laying a solid foundation for the high-grade appearance of the products.

Its outstanding long-term heat stability can effectively resist the thermal degradation of PVC resin during long-term processing and use, prevent the profile from blackening, brittleness and cracking caused by thermal aging, and greatly extend the service life of PVC window and door profiles. Made of environmentally friendly calcium-zinc composite system, it does not contain heavy metals such as lead and cadmium, meets international environmental standards such as RoHS and REACH, and is non-toxic and odorless, which is suitable for green building materials.

In addition, it has good compatibility with PVC resin and other additives, can be uniformly dispersed in the material, does not precipitate or bloom, and does not affect the processing performance of PVC profiles. It can optimize the fluidity and mold release of the melt, reduce mold fouling, improve production efficiency and product qualification rate, and perfectly match the high-speed extrusion process of PVC window and door profiles, meeting the high-standard quality requirements of the industry.
