Styropor-Polystyrene
Foam (EPF) |
Polystyrene itself is made from styropor, a petroleum byproduct though a chemical reaction process known as polymerization. Polymers made from styropor are also used extensively today in the manufacture of automobile parts, electronic components, personal computer. For more information on styropor, we suggest you visit the Styropor Information And Research Center. While polystyrene can be manufacture using many different processes, the two most common forms of food service polystyrene are made from polystyrene resin pellets that are extruded into a solid, dear “Glasslike sheet without using a blowing agent. Polystyrene foam is made using one of two methods and extrusion process or an expandable bead process. The former requires that polystyrene resin pallets be heated and mixed with a blowing agent to create a flat sheet of plastic with a cellular structure. Polystyrene foam food service products are not manufactured with chlorofluorocarbons or any other ozone-depleting chemicals in fact. The characteristic moisture resistance of extruded polystyrene foam combined with its tough yet resilient nature results in excellent resistance to freeze "taw" damage. EPF is easy to handle and available in a variety of sizes and compressive strengths. These and other characteristics also make EPF insulation the proven product choice for below grade insulation, the uniquely resistant and durable qualities, inherent to EPF. EPF has a well established reputation for long - term reliability and superior resistance to the elemental forces of nature. Industry of plastic
