Recyclable Thermoplastic PET Foam Sandwich Panels
Save Resources and Protect The Environment.
The Importance of PET Recycling
PET (Polyethylene Terephthalate) is a common thermoplastic polymer. It is made from terephthalic acid and ethylene glycol through the polyesterification reaction. It is a transparent, strong and lightweight plastic. Perhaps in many people’s perception, these PET products are a major culprit in polluting the environment. In fact, however, post-consumer PET should not be considered waste but a resource because they are 100% recyclable. The recycling and reuse of PET is a sustainable development practice that helps reduce dependence on virgin petroleum resources, reduce waste disposal pressure, and reduce environmental pollution. In addition, by recycling PET, greenhouse gas emissions can be reduced.
New FRP Sandwich Panels – Thermoplastic PET Sandwich Panels
FRP sandwich panels play an important role in many industries and are an economical and high-performance composite material. But after its service life expires, it needs to be recycled. Currently, most of the materials used on the market are thermosetting FRP, which has high recycling costs and causes certain harm to the environment. TOPOLO is committed to developing lightweight composite materials. After our continuous exploration and research, we have invented a new type of fiberglass composite panel with high reuse rate, safety and environmental protection – recyclable Thermoplastic PET foam core sandwich panels. Thermoplastic PET sandwich panels subvert the existing manufacturing methods of foam sandwich panels and are an innovation and breakthrough in composite materials.
Unique and Environmentally Friendly Manufacturing Process
100% Recyclable Materials
In terms of materials, the skin of the recyclable PET foam sandwich panel is CFRT (continuous fiber reinforced thermoplastic sheet), which uses PET resin with the same plastic system as the core material as the matrix. Both the PET foam core and PET resin fiberglass skin are 100% recyclable.
In terms of manufacturing process, unlike other foam system sandwich panels that require the use of glue as an adhesive, the processing of PET sandwich panels uses a hot-melt composite process, which combines the thermoplastic sheet with the PET foam by heating it. No adhesive is used during the processing, and no odor or harmful substances are released.
The use of more environmentally friendly materials and production technologies has not only not reduced the performance of PET sandwich panels, but has greatly improved them.
Wider Application Areas
Thermoplastic PET sandwich panels can replace aluminum panels, plywood and other metal or plastic plates to reduce the weight of the box and provide a longer service life. It is widely used in box trucks, travel trailers, boats, and mobile buildings, etc.
