MicroZOTE closed-cell roll foams are produced using microcellular extrusion technology which uses CO2 as a blowing agent, making them inert and environmentally friendly for food contact and medical applications. They have a uniform microcellular structure providing good mechanical properties and a consistent, smooth surface finish. MicroZOTE foams are available in low-density polyethylene and polypropylene in a range of densities and thicknesses from 250-400 kg/m3 and 0.5-2.5 mm respectively.
