What is polyurethane spraying and what are its advantages and disadvantages
1. What is polyurethane spraying? Polyurethane spraying uses isocyanate and polyether as the main raw materials. It is a high molecular polymer that is foamed on-site through high-pressure spraying under the action of various additives such as foaming agents, catalysts, and flame retardants, mixed through special equipment. Polyurethane rigid foam is a new synthetic material…
