The Impact of Polyurethane Catalysts on Volatile Organic Compound (VOC) Emissions
Abstract: Polyurethane catalysts play a critical role in the formation and properties of polyurethane products. However, these catalysts can also influence the emission levels of Volatile Organic Compounds (VOCs), which are known for their potential environmental and health impacts. This paper explores the relationship between polyurethane catalysts and VOC emissions, analyzing how different types of catalysts affect the VOC content in finished products. Through an extensive review of both domestic and international literature, this study provides insights into selecting catalysts that minimize VOC emissions while maintaining product quality.
Introduction: Polyurethanes are widely used in various industries, including automotive, construction, furniture, and packaging. They are valued for their durability, flexibility, and versatility. However, during the production process, certain chemicals, such as isocyanates and polyols, react under the action of catalysts to form polyurethane. Among these reactions, the choice of catalyst is crucial as it not only affects the reaction rate but also the level of residual monomers and other volatile substances, contributing to VOC emissions.
