Polystyrene Foam Recycling

The main ways of polystyrene foam recycling are: reduced capacity before granulation, crushed for a variety of filling materials, cracking oil or the recovery of styrene and other methods.

1. Granulate after reduce the capacity of the xps raw material: polystyrene foam can be melt extrusion granulation to make of recycled pellets, but the volume is large, and do not convenient for transport, usually should reduce its capacity before recycle it to do other products. The methods of reduce the capacity are the mechanical method, the solvent method and the heating method.

2. Used for the filler after crushing: polystyrene foam products can be used as a filler after crushing, and then to make various products.

① re-molding into foam products

② concrete composite board products

③ gypsum brick

④ used as a asphalt enhancer

⑤ used as soil modifier

3. Cracked for oil or recycle polystyrene: the method of waste polystyrene foam plastic cracking for oil as follows:

Waste polystyrene foam deal with heat and reduction in advance, and then crackle distillation styrene.

4. Other functions: waste polystyrene foam can be used in the manufacture of coatings and adhesives

① paint: after crushing expanded polystyrene foam, and then add the appropriate solvent can be made of paint,

Polystyrene foam is useful for polystyrene bead molding. For the use of household appliances such as packaging or frozen food packaging foam; there are a few instant noodles bowl made of polystyrene beads.
