Recycled PET Foam

Recycled PET foam is a closed-cell thermoplastic structural foam made from recycled polyethylene terephthalate (PET) through a specific foaming technology. TOPOLOGROU has developed a foam board made of recycled PET chips to reduce environmental impact and achieve weight reduction. By using this foaming technology, it has become possible to produce a product that is lighter and harder than wood boards.

Environmental protection and sustainability

  • The raw materials come from recycled PET plastics, which can effectively reduce the pollution of plastic waste to the environment.
  • The recycled PET foam after use can be recycled and foamed into materials, which is in line with the concept of sustainable development.
