Styrofoam™ is the trademarked name for extruded polystyrene foam, an invention of the Dow chemical Company that has been in production for more than 50 years. Nearly anyone who has purchased coffee “to go” has heard the container being referred to as a Styrofoam™ cup. However, this material has never been used to make disposable coffee cups. For that matter, it’s never been used to make portable picnic coolers either, another misconception. These products are actually made from expanded polystyrene foam (EPS) in the form of beads, commonly known as packaging “peanuts.”

    In addition, many recycling companies will not accept products made from polystyrene foam left on the curb, presumably because the market for reclaiming this material is limited. For these and other reasons, polystyrene foam is banned in some regions, such as Portland, Oregon, and Orange County in California.

    In the nowadays world, it is still very popular in a lot of countries. People are using the PS foam sheet for flooring, meat, foam egg boxes, etc. This ps foam sheet was extruded by the PS foam sheet extruder. Usually we produce the polystyrene foam sheet with the pe foam sheet extrusion line, and then we produce the products we need with the automatic vacuum forming and cutting line. Tongyi company is a professional company who produce these kinds of foam extrusion machines with more than 20 years experience.
