Solid State Expansion

Ad-air^® clean technology creates a microcellular structure in common thermoplastics. In contrast to melt-state chemical foaming processes, this technology does not require any harmful chemicals or VOCs, and the location and size of the microbubbles is precisely controllable. The material can then be printed as a flat sheet or converted by a number of processes such as: folding, thermoforming and convolute forming.
