Polyurethane foaming machine is a special equipment for infusing and foaming polyurethane foam. As long as the performance indicators of polyurethane components (isocyanate components and polyether polyol components) meet the requirements of the formula. Through this equipment, uniform and qualified foam products can be produced. It is made of polyether polyol and polyisocyanate in the presence of a variety of chemical additives such as blowing agent, catalyst, emulsifier, etc., through chemical reaction to foam to prepare foam.
