1. The formation of polyurethane foam needs to go through two stages of foaming and curing. From the beginning of the mixing of the black and white materials to the stop of the foam volume expansion, this process is called foaming. During the foaming process, the system releases a large amount of re

As a polymer material with excellent performance, polyurethane has become the fifth largest plastic after polyethylene, polyurethane, polypropylene, and polystyrene. The total global output has exceeded 10 million tons per year. Polyurethane high-pressure foaming equipment essential. In recent years
