soufa is working on the development of non-combustible wood. We have been conducting research and development with partner companies and succeeded in producing wood with the certification level of noncombustible materials. Unlike other companies’ non-combustible wood, there is no stickiness due to efflorescence or leaching. Post-processing such as painting is possible without impairing the wood texture. We believe that the permeability is significantly better than phosphoric acid. Therefore, impregnation at normal pressure is possible.

• We provide flame retardants for non-combustible wood production. Please contact us if you are considering developing non-combustible wood.
