Immediately after extrusion, solid materials expand when heated, resulting in post-foamed extruded products!
Toho is a manufacturer of extrusion and profile extrusion products. "Extrusion" is a technology that literally means "shaping by pushing out." Utilizing extrusion technology, we create products that can flexibly cater to various genres. "Post-foaming extrusion" refers to a process where solid materials are foamed by applying heat after extrusion. Foaming ratios can reach up to 50 times, and it is possible to change the foaming start temperature (above 90°C). This technology is used for molding materials such as FRP and CFRP (as a substitute for air balloons), fillers, sealants, fire retardants, and more. *For more details, please download the catalog.
