Recycling of polystyrene foam products is the focus

Polystyrene (PS) refers to a polymer synthesized by radical addition polymerization of a styrene monomer, which is a colorless and transparent thermoplastic. Due to the characteristics of light weight, non-absorbent, acid and alkali resistance, aging resistance, good heat insulation, sound insulation, shockproof and decorative, and good formability of polystyrene after foaming , polystyrene foam products are widely used in instruments. , home appliances, handicrafts, industrial and food packaging.

The wide application of polystyrene foam products inevitably generates a large amount of waste, which has a great impact on the environment. Although it is now strongly advocated to promote the use of biodegradable plastics, it is still unrealistic to use degradable plastics widely. Degradable plastics also have many problems, such as uneven quality, poor heat resistance, incomplete degradation, and large pollution in the production process. Even if fast food box-like foam products use degradable materials, polystyrene foam is still widely used in instrument shock absorbing packaging, building decoration materials and the like. Therefore, from the practical point of view of reducing pollution and saving resources, the focus should be on the recycling of waste polystyrene foam products.
