What is a polyurethane sponge pore opener?

Polyurethane sponge pore opening agent is an additive used to prepare polyurethane sponge materials. Polyurethane sponges are commonly used in the manufacture of seats, cushions, cushions and other soft furniture and products such as car seats. A cell-opening agent is a substance added during the polyurethane foaming process. Its function is to form a bubble or hole structure in the material when the polyurethane sponge is formed, thereby making the sponge have better softness, breathability and elasticity.

Cell openers can be physical or chemical. Physical cell opening agents are substances that evaporate during the foaming process. They form bubbles or hole structures through volatilization. The chemical pore opening agent is a substance that undergoes a chemical reaction to produce gas during the foaming process, thereby forming pores.

The amount and type of polyurethane sponge pore opening agent can be adjusted as needed to achieve the desired sponge material properties. By rationally selecting and controlling the pore opening agent, the density, hardness, air permeability and other characteristics of the polyurethane sponge can be adjusted to meet the requirements of different products.
