Microcellular polymeric foams

Patent Granted Microcellular plastic foam is a plastic that has been specially fabricated so as to create micro-pores or cells in the polymer matrix. The common definition includes foams with pore size on the order of 10 micrometers in diameter (from 0.1 to 100 micrometers typically.) Since the size of cells is close to the wavelength of light, to the casual observer this foam retains the appearance of a solid light colored plastic.
