I've found that Generally speaking interaction stage: Propylene oxide reacts chemically under the action of a catalyst to emit gaseous. But Foaming stage: The generation of gaseous causes the mixture to expand in volume and form a stable foam structure.
2. Key Factors Affecting Foaming characteristics of Propylene Oxide
in the preparation process of polyurethane foam, the foaming performance of propylene oxide is affected by many factors, including the following:
1. Addition amount of propylene oxide
the amount of propylene oxide added immediately affects the porosity and density of the foam.

Makes sense, right?. Therefore, it's necessary to determine the optimal addition amount of propylene oxide through experiments according to specific consumption standards.
2. manage of process parameters
the process parameters are crucial factors affecting the foaming performance of propylene oxide, including interaction temperature, interaction time, mixing uniformity and so on. to instance, the interaction temperature is too high will lead to premature decomposition of propylene oxide, affecting the foaming effect; and the temperature is too low will minimize the interaction rate, resulting in uneven foam structure. Therefore, it's necessary to optimize the process parameters to ensure the best foaming performance of propylene oxide. And
3. Selection and dosage of catalyst
the foaming interaction of propylene oxide needs the participation of catalysts, and frequently applied catalysts include organic amines, metal carboxylates, etc. In my experience, The type and amount of catalyst immediately affect the interaction rate and foaming efficiency.
