In injection molding of PVC fittings, due to the longer residence time in the barrel and the thicker wall sections of fittings, a robust thermal stabilizer is essential. A PVC heat stabilizer for fittings prevents degradation and discoloration during molding, while ensuring long-term mechanical strength and surface quality.
With expertise in both lead-based stabilizers and the development of modern Calcium-Zinc (Ca-Zn) systems, we provide a comprehensive portfolio of stabilizers tailored for fittings. Lead-based stabilizers remain cost-effective and reliable for many injection molding operations, while Ca-Zn stabilizers offer a sustainable, lead-free alternative that complies with international drinking water standards and ensures excellent whiteness and processing stability.
Our R&D-driven approach, supported by extensive industrial know-how, has led to the development of formulations that guarantee thermal resistance, surface uniformity, and consistent performance under real production conditions.
In addition, our specialized stabilizer systems are designed to perform effectively with different PVC grades, including S65 and S60, enabling manufacturers to achieve high-quality fittings across a variety of raw materials
