It is used for the production of flame retardant products such as soft foam, rigid foam, semi rigid foam polyurethane foam, polyvinyl chloride, polystyrene, cellulose acetate, ethyl cellulose and phenolic plastics, polyvinyl acetate, and gun foam sealant. It is particularly recommended that rigid foam polyurethane foam be used for better thermal conductivity and flame retardant efficiency.
Reference Addition: 8-15% has low viscosity at low temperature. Usually it is also used with melamine, antimony trioxide or zinc borate to improve flame retardant efficiency and smoke suppression, making the product more in line with environmental requirements. It can be injected directly into the mixing head as a single component in the foaming process, or mixed with polyether polyols before foaming. At the same time, the viscosity of polyols can be reduced.
