Problems solved by technology

However, the rigid polyurethane foam used for insulation boards has a porous structure, which makes it easier to ignite than ordinary plastics, and releases a large amount of toxic gases such as hydrogen cyanide, CO, and NO during the combustion process, causing great potential hazards , plus its strength is not very high, which limits its application range
