In PET foam, the main component is polyethylene terephthalate. It is a kind of closed-cell thermoplastic structural polyester foam with certain shear and compressive strength, so it is often used as the core material of sandwich structure materials. It has good specific stiffness, and specific strength, its compression, tensile, shear, and bending strengths are excellent. It also has good dimensional stability and is easy to process, suitable for various processes. It is an ideal core material for lightweight & high-strength composite sandwich structures. It provides excellent fatigue resistance, impact resistance, and deficient water absorption. It also has good thermal and acoustic properties.
- Suitable for all resin systems.
- It can achieve zero emissions of greenhouse gases, which is very conducive to environmental protection.
- Through thermoforming, complex body structures can be achieved.
- Has good shear and compression properties.
- Excess material created during the production process can be reused to make new materials.
- During processing, it can withstand temperatures around 150°C for a short period of time.
- During its service life, it can withstand temperatures of about 100 °C for a long time.

Benefiting from the features of rigid foam structure, PET foam can be widely used in all kinds of composite sandwich panels and products with the curve as core material, can be bonded with multiple kinds of surface materials, processing methods such as RTM, hot press molding. As core materials, by the lower price, higher physical performance, and easy processing, PET foam is gradually being used to replace traditional sandwich core materials such as Basha wood, and PVC in the industry.
At present, TOPOLO series PET foam products have been widely used in wind power blades and hoods, new energy van-truck bodies, and ship fields.
