1.1 The function of pore opener

The pore opener mainly plays a role in regulating the foam structure in the production process of polyurethane sponges. By controlling the porosity of the foam, the porosant agent can significantly improve the breathability, elasticity and compression properties of the foam. Specifically, the functions of pore-opening agents include:

Adjust the foam structure: The pore opener can promote the bursting of bubbles inside the foam, forming an interconnected pore structure, thereby increasing the pore openness of the foam.

Improved breathability: Foams with high porosity have better breathability and are suitable for application scenarios where good ventilation performance is required.

Enhanced Elasticity: The pore agent can optimize the elastic modulus of the foam so that it can quickly return to its original state after being compressed.

Improving compression performance: By adjusting the pore rate, the pore agent can improve the compressive permanent deformation performance of the foam and extend its service life.

1.2 Selection of pore agent

Selecting the right pore opener is the key to optimizing the production process of soft foam products. Here are a few factors to consider when selecting a pore opener:
