Production Process of Polyurethane Rigid Foam for Refrigerators (two)

Precisely control the proportion of various raw materials according to different refrigerator models and thermal insulation requirements to ensure the optimal performance of the polyurethane rigid foam. Generally, the optimal formula is determined through experiments and experience. For example, the molar ratio of polyol to isocyanate is usually between 1:1 and 1:1.5, the amount of blowing agent is generally about 10%-20% of the polyol amount, and the amount of catalyst is adjusted according to the reaction rate and foam performance requirements.

Production Process of Polyurethane Rigid Foam for Refrigerators (one)

The polyurethane rigid foam refrigerator process mainly refers to the use of polyurethane rigid foam as a filling material during refrigerator manufacturing to enhance the refrigerator's thermal insulation performance and energy-saving effect. Here is a detailed introduction:
