PS pellets made by INTCO can be the good raw material of XPS insulation board

XPS board, also known as extruded polystyrene insulation, is made of polystyrene resin as raw material and other raw materials and polymer contents, and the catalyst is mixed and injected by special technology.

The raw material of XPS is polystyrene pellets, which are first mixed with various chemicals and then heated until the pellets are liquefied. When pellets cool, they become beads. Then the beads are heated and injected into flat molds and when the molds cool, the material is cut into panels of various lengths, widths and densities to use as insulation. The final product is rigid, dense and waterproof. As a result, XPS is commonly used for roofing and below grade to insulate cement slabs and foundation walls.

As a raw material of XPS, PS pellets are in great demand. It can be divided into two types: primary PS granules and regenerated PS pellets. Generally, raw PS pellets can be made directly from oil, while regenerated pellets are made from EPS waste. In spite of the superior quality of the virgin ones, the price of them is much higher than the recycled PS pellets. Meanwhile, in many cases, the recycled PS pellets in some manufacturing companies can totally replace the virgin ones for its perfect characteristics and property.
