Super Constructa Flexible Foam

Super Constructa Foam let you custom fabricate wheelchair and bed support systems. Create trunk and head supports, body positioners, abduction wedges, as well as leg and arm troughs using these lightweight closed-cell foam materials.

Super Constructa Foam is a smooth blue material available in sheets only. Less stiff than Constructa Foam with a velvety closed-cell surface. Stands up to repeated use.

Cut Super Constructa Foam with a fine blade or a knife with a razor blade.

Bonding
Constructa Foam bonds after application of direct heat. Use a heat gun to thoroughly warm both surfaces. Hold the gun 4" to 6" away from the material and pass the heat back and forth until the surfaces appear glassy. Heat one minute longer, then press the surfaces together. If either surface is allowed to cool before bonding is complete, the bond will be weak.

Both foams can be bonded with 3M Spray 90 Adhesive. Adhesives are more effective on larger surfaces. Follow the adhesive manufacturer's directions. Apply weight and cure for 24 hours before use to ensure total contact.

Padding
Pressure-sensitive paddings bond easily to these materials. To strenghten bond, warm adhesive backing with a heat gun before applying to the surface. In this case, only the adhesive surface should be warmed. Molestick™, Soft Sponge™ and Plastazote® are often used for wheelchair adaptations. They will provide extra protection for fragile skin.
