Processing Aids in PVC production

توشته شده توسط Fatemeh Rajabi

Introduction In PVC production, one of the biggest challenges is shaping the material due to the high viscosity of the molten PVC. To overcome this challenge, Processing Aids are used. These acrylic-based additives improve melt flow, enhance the surface quality of the final product, and reduce energy consumption during the melting and shaping process. What Are Processing Aids? Processing Aids are acrylic-based additives that are incorporated into PVC formulations to improve the flow of the

Barium-Cadmium-Zinc Stabilizer

توشته شده توسط Fatemeh Rajabi

Ba-Cd-Zn stabilizers are a combination of salts derived from three key metals, each playing a specific role in preventing PVC degradation: Barium: Enhances thermal stability and prevents the structural degradation of PVC at high temperatures. Zinc: Ensures better initial color and prevents discoloration during the early stages of production. Cadmium: Improves initial color and provides light stability, preventing discoloration when exposed to light. The Key Role of Cadmium: In some applications, a Barium-Zinc combination (without

The Impact of Volatility on PVC Granules

توشته شده توسط Fatemeh Rajabi

During the production process of PVC granules, one of the major challenges is bubble formation, which negatively affects the final product’s quality. At high temperatures, PVC undergoes dehydrochlorination, resulting in the release of hydrogen chloride gas (HCl). If this gas is not promptly removed from the process, it can become trapped within the granules, leading to bubble formation. In addition to HCl, other by-products from PVC decomposition, such as plasticizer evaporation, may also contribute to
