The Role of Catalysts in Polyurethane Manufacturing

Before diving into the specific applications of CS90, it’s important to understand the role of catalysts in polyurethane manufacturing. Polyurethane is formed through a chemical reaction between an isocyanate and a polyol. Without a catalyst, this reaction would proceed very slowly, making it impractical for industrial use. Catalysts speed up the reaction by lowering the activation energy required for the formation of urethane bonds.

There are two main types of catalysts used in polyurethane production: amine catalysts and organometallic catalysts. Amine catalysts, like CS90, primarily promote the reaction between isocyanates and water to form carbon dioxide and amine salts. This reaction is crucial for the formation of foam cells in rigid and flexible foams. Organometallic catalysts, on the other hand, are more selective and are often used to promote the reaction between isocyanates and polyols, which is essential for the formation of hard segments in the polymer.

To achieve this, they conducted extensive testing to optimize the molecular structure of CS90, ensuring that it would promote the formation of urethane bonds quickly and efficiently.

One of the most significant breakthroughs in the development of CS90 was its ability to promote the formation of carbon dioxide as a blowing agent. This not only eliminated the need for environmentally harmful substances like HFCs but also improved the performance of the final product. The smaller, more uniform foam cells created by CS90 led to better thermal insulation and mechanical properties, making it a valuable addition to the polyurethane industry.

Safety

Safety was a top priority in the development of CS90. Researchers knew that any new catalyst would need to be safe for workers to handle, especially in industries like construction and automotive, where large quantities of polyurethane are produced. To ensure worker safety, they focused on reducing the odor and volatility of CS90, making it less likely to cause respiratory issues or skin irritation.

Additionally, researchers worked to minimize the amount of residual isocyanate in the final product. Isocyanates are known to be harmful to human health, so reducing their presence in polyurethane products was a key goal. By optimizing the reaction conditions, researchers were able to significantly reduce the amount of residual isocyanate, improving the overall safety of the product.
