Expanded Polystyrene foam, also known as EPS, is a type of plastic. Improper disposal of EPS foam can cause serious environmental pollution. A polystyrene foam shredder can better and easily crush waste foam, so people can use it to solve the problem of waste foam. The polystyrene foam shredder can crush various loose foam plastics into compact sizes, and the crushed EPS foam can be used to make other products. Today, I will recommend a commonly used polystyrene foam shredder for your reference.

EPS Foam

The GSE-3 single-shaft shredder is an ideal EPS foam shredder

The GSE-3 single-shaft shredder is an upgraded product of the GEP ECOTECH single-shaft shredder series. It integrates power, feeding, crushing, output, maintenance, and intelligent protection, not only comprehensively upgrading the product structure, but also significantly improving the overall crushing capacity, scope of application, and service life. The GEP ECOTECH third-generation European version single-shaft shredder can easily crush a large amount of EPS foam, and the output is uniform, which can ensure high productivity and stable operation of the production line.

Features of the third-generation high-power single-shaft shredder are:

Energy-saving + large cutting force and production efficiency

Precise rotor/stator cutting system

Separately installed and replaceable cutting plate

Fast replacement of the screen can achieve precise particle size control

Segmented crushing chamber bottom plate with brass guide rails

PLC unit with automatic reverse and power-off function

Use of crushed polystyrene foam (EPS)

  • Fill modified other materials: Crushed EPS foam can be filled in cement or added with a binder to produce lightweight building materials such as cement partitions, lightweight roof insulation boards, and lightweight concrete.
  • Thermal decomposition to recycle styrene and oil: Thermal decomposition and recycling have recently been highly regarded as an effective and scientific method for recycling all kinds of waste plastics. Crushed EPS foam can be processed further in the recycling process to recover styrene and oil.
  • Preparation of coatings and adhesives: Crushed waste EPS foam can be dissolved in a reaction kettle, and then added with pigments and fillers to create polymer adhesives or added with plasticizers, surfactants, thickeners, and defoamers or other materials to create water-based coatings.

Crushed EPS foam has many uses, and we should continue to explore the road to EPS foam crushing and recycling. In addition to the GSE-3 European version single-shaft shredder, GEP ECOTECH can also provide other EPS foam shredder models such as GDI double-shaft shear shredder, GSD double single-shaft shredder, and many others.
