| Use | As a highly efficient tertiary amine catalyst, it is suitable for the production of almost all foam plastic products, mainly for the production of soft foam products, especially for high resilience and RIM products. It is characterized by high catalytic activity, stable foaming, large tolerance to tin, easy to adjust the formula, and the physical and chemical properties of the products produced by it are better than other products. |
