At NINGBO INNO PHARMCHEM CO.,LTD, we believe that the true value of a chemical additive lies in its versatility and the tangible benefits it brings to a wide range of applications. Our Calcium Zinc Stabilizers exemplify this philosophy, offering robust performance enhancement for diverse PVC products, from delicate transparent films to resilient pipes and profiles.

The fundamental role of PVC stabilizers is to protect the polymer during processing and throughout its service life. PVC’s susceptibility to heat, light, and oxygen necessitates effective stabilization to prevent degradation, which manifests as discoloration, embrittlement, and loss of mechanical strength. Our Calcium Zinc Stabilizers, a synergistic blend of calcium and zinc compounds along with specialized organic additives, provide a comprehensive solution. They excel in neutralizing hydrochloric acid, preventing chain scission, and acting as antioxidants, thereby preserving the polymer’s integrity and aesthetic appeal.

In the realm of transparent films, such as rolling films and cling films, the demand for exceptional clarity and optical quality is paramount. Our Calcium Zinc Stabilizers are specifically formulated to meet these stringent requirements. They contribute to a low initial color, excellent color retention, and minimal haze, ensuring that the transparency of the PVC film is preserved. This makes them ideal for applications like food packaging, medical blister packs, and protective coverings where visual appeal and product visibility are key.

Beyond films, the versatility of our stabilizers extends to rigid PVC applications. For pipes and fittings, long-term thermal stability and resistance to weathering are crucial. Our Calcium Zinc Stabilizers provide the necessary protection against environmental degradation, ensuring the longevity and reliability of these essential building components. In injection molding and extrusion processes for various profiles and parts, these stabilizers enhance melt flow, improve surface finish, and reduce processing issues, leading to higher quality end products and increased manufacturing efficiency.

A significant advantage of our Calcium Zinc Stabilizers is their environmentally friendly profile. They are free from toxic heavy metals like lead and cadmium, making them compliant with international safety and health regulations. This is particularly important for PVC products intended for food contact, medical use, or children’s toys. By choosing NINGBO INNO PHARMCHEM CO.,LTD, manufacturers are opting for sustainable solutions that enhance product performance while ensuring safety and compliance. Our continuous research and development efforts are focused on expanding the capabilities of our stabilizers, further solidifying their position as indispensable additives in the modern PVC industry.
