Polystyrene sheets are thin layers made of polystyrene foam. These sheets are often referred to as Styrofoam sheets. This foam consists of petroleum-derived hydrocarbon molecules that are injected into the air and molded into a sheet of roughly plywood or drywall size and shape. In addition to providing excellent insulation properties, these thin plates also have a certain degree of structural strength, making them an effective choice for a wide range of applications.

There are two basic varieties of polystyrene boards that are manufactured in different ways. Extruded polystyrene sheets (XPS) are made of polystyrene beads that melt and are forced through a metal mold. These sheets have a compact closed-cell structure that is harder and stronger than other polystyrene sheets. Expanded Polystyrene Sheets (EPS) are made of polystyrene beads that are filled with air and pressed together in a mold. The structure of EPS is slightly lower than that of XPS, making it less effective in structural applications.

One of the most common uses of polystyrene sheets is as a form of building insulation. These panels can be mounted under wall cavities or roofs or side panels to help improve the thermal resistance between the exterior and interior surfaces. Although polystyrene sheets offer many advantages to users, one of the major advantages associated with this material is its excellent insulating properties.

Polystyrene sheets also have many potential limitations or disadvantages. The cost of these boards is higher than alternative insulation materials, which may affect the construction budget of homes and commercial buildings. Polystyrene foam plastic is widely used in our lives, but after discarded in the water or soil, it won’t rot for years, affecting the production of crops, and recycling and reuse will bring people more interest, so it is very important to take such action as polystyrene recycling.

GREENMAX, belongs to INTCO recycling, can well solve the problem, because it has many kinds of recycling machines to deal with waste plastic. One of is the melting machine which can especially deal with the polystyrene sheets. This machine can crush these sheets first, and then after heating and extruding, these sheets will become the densified ingots, with the volume reduction ratio up to 90:1. Because of this Styrofoam insulation recycling, the melted sheets are easy to transport and will have little pollution on the environment.
