In the production of polyurethane products, foam generation is a common yet challenging issue. This uncontrolled foam not only hampers production efficiency but also leads to final product defects such as pores, uneven density, and surface imperfections, directly impacting product performance and customer satisfaction. Traditional methods often provide only temporary relief or introduce new compatibility problems.
Addressing this core pain point, Chemi Tech leverages profound expertise in materials science to develop a series of high-efficiency defoamers specifically for polyurethane. Our solution is not merely about adding a chemical; it involves comprehensive support from prevention to elimination, based on a deep understanding of the foaming mechanisms within polyurethane systems.
Our specific resolution steps are as follows: First, our technical team conducts a detailed analysis of the client's production process and raw material system to accurately identify the root cause of foam formation. Second, according to the system characteristics (such as flexible foam, rigid foam, different isocyanate indexes, etc.), we select the most compatible defoamer model from the Chemi Tech product portfolio, ensuring both high efficiency and system compatibility. Then, we provide clear guidance on addition points, dosage, and optimization of process parameters for seamless integration. Finally, we offer on-site or laboratory application testing support to verify defoaming effectiveness and evaluate the final product performance.
We once served an enterprise manufacturing polyurethane seals, where the cured products often exhibited tiny internal bubbles, leading to unstable sealing performance. Through analysis, we found that excessive air was entrapped during the raw material mixing process, and the system itself had insufficient inherent defoaming capability. Chemi Tech recommended a modified silicone defoamer with excellent foam suppression and rapid deaeration functions and guided its addition in the late stage of the mixing phase. After application, internal bubbles in the products were significantly reduced, density uniformity improved, sealing test pass rates increased substantially, and production efficiency was enhanced due to reduced waste.
Choosing Chemi Tech means you acquire not just a defoamer product, but a reliable solution package for polyurethane foam challenges. We are committed to helping our clients improve product quality, optimize production costs, and achieve more stable and efficient production operations.
