2. Introduction to polyurethane casting process
2.1 Process Overview
The polyurethane casting process is the process of mixing polyurethane raw materials (polyols, isocyanates, catalysts, foaming agents, etc.) in a certain proportion, injecting them into the mold, and forming polyurethane products through chemical reactions. This process is widely used in automotive seats, furniture, soles, electronic packaging and other fields.
2.2 Process flow
- Raw Material Preparation: Prepare raw materials such as polyols, isocyanates, catalysts, foaming agents, etc. according to product requirements.
- Mix: Mix the polyol, isocyanate, catalyst, foaming agent, etc. in proportion and stir evenly.
- Casting: Inject the mixed raw materials into the mold.
- Reaction: The raw materials undergo chemical reaction in the mold to form polyurethane products.
- Discharge: After the reaction is completed, remove the product from the mold.
- Post-treatment: Perform post-treatment processes such as trimming, grinding, and spraying of products.
2.3 Process Difficulties
- Reaction rate control: The reaction rate of polyurethane is too fast or too slow, and it will affect product quality and needs to be precisely controlled through a catalyst.

III. Application of Jeffcat TAP amine catalyst in polyurethane casting process
3.1 Reaction rate control
Jeffcat TAP amine catalysts can effectively control the reaction rate of polyurethane to ensure smooth progress of the reaction processOK. By adjusting the amount of catalyst, the reaction time can be accurately controlled to avoid problems such as bubbles and shrinkage caused by excessive reaction, or inefficiency caused by slow reaction.
