The material is a cast thermo-setting resin with extraordinary memory properties. Most polymers have some 'memory' but this one can be stretched by up to 200% and still remember its original condition.When heated above 70°C, it softens, and can be shaped by stretching, bending, blowing etc. When cool it retains its new shape, but if the material is re-heated to 70°C, it reverts to its flat sheet condition.
Sheet size is approximately 3mm thick x 100mm x 150mm.
