In the production process of polyvinyl alcohol (PVA), foam problems often become a key bottleneck restricting efficiency and quality. From monomer polymerization to post-treatment processes, the continuously generated foam not only reduces the effective volume of the reactor and creates a risk of overflow, but also slows down the production pace and affects product yield and uniformity. Traditional defoaming methods often face the dilemma of short-lived effects, high dosage, or adverse effects on the final product's transparency and performance.


In response to these common industry challenges, drawing on a deep understanding of polyvinyl alcohol processes, Chemi Tech has developed a series of dedicated defoamers. The core of our solution lies in precise molecular design, ensuring the defoamer can quickly penetrate and destroy the foam film while remaining highly compatible with the system, avoiding fish eyes or adverse effects on the product's subsequent processing performance. Its outstanding foam-suppression ability maintains the stability of the production system over the long term.


The specific implementation steps are clear and well defined: first, our technical team conducts a professional analysis of the customer's production process, foaming stages, and foam characteristics. Then, we recommend a suitable Chemi Tech defoamer model and provide samples for on-site or simulated working-condition testing to determine the optimal dosing point and dosage. Finally, we provide continuous technical follow-up to ensure the defoaming solution remains effective over the long term and can be optimized according to process adjustments.


We once assisted a synthetic materials company in East China in addressing the foam problem in the post-washing stage of its PVA production line. The company's original defoaming solution was ineffective, and the foam led to low washing efficiency and high drying energy consumption. After introducing Chemi Tech's customized defoaming solution, the foam was controlled immediately and durably, the washing process time was shortened by about 15%, the impurity content in the product decreased significantly, and overall production fluidity and batch-to-batch stability improved. The customer was also very satisfied with the transparency of the final product.


Choosing Chemi Tech means choosing a defoaming partner that fits your process deeply and pursues long-lasting stability. We are committed to using professional products and technical support to help polyvinyl alcohol manufacturers break free from foam constraints and achieve cost reduction, efficiency improvement, and quality upgrading.
