Production method

Unlike conventional foaming method with VOCs, inorganic gases are used in its production.

Based on internal studies, SunForce is 40 to 50% lighter compared to an aluminum beam of the same bending strength.
The differences of environmental impacts during production of aluminum and SunForce are as follows:

SunForce uses half of the total amount of energy for production of aluminum.
SunForce emits only 3/4 of CO2 emission as compared to aluminum during production.

NOTE: Energy for foaming process is estimated by AsahiKASEI.


SunForce can be treated and recycled the same way as thermoplastic resins (melt and reuse as resins). It can also be used as an energy source by thermal recycling.
