For many new products and technologies, only those that have passed theoretical and practical tests are worth recommending. The same is true for polyurethane products. It is recommended that you weigh the relationship between price and value when purchasing polyurethane products. The self-discipline

As a common product, high-pressure foaming machine has widely appeared in our real life, and the development trend is increasing:1. Polyurethane products are made of isocyanate and polyether as the main raw materials. Under the action of various additives such as blowing agent, catalyst, flame retar

Because foaming relies on heat, if there is no heat, the foaming agent in the system cannot evaporate and foam plastic cannot be formed. The heat comes from two aspects, one is the heat produced by the chemical reaction, and the other is the heat provided by the environment. The heat of chemical rea
