Advantages of using FRP (GRP) sheets as skins for PET foam core sandwich panels
- Strength-to-Weight Ratio
FRP sheets are lightweight yet highly durable, providing excellent strength without adding excessive weight.
- Durability
FRP is resistant to corrosion, chemicals, and UV degradation. It is much more durable than many other materials like wood or metal, ensuring the longevity of the sandwich panel in harsh environmental conditions.
- Impact Resistance
FRP sheets have high impact resistance compared to other materials, such as traditional metal or plastic.
- Lightweight Construction
Combining PET foam with FRP sheets results in a lighter composite panel compared to solid metal or wood panels.
- Aesthetic Options
FRP can be made in various colors and finishes, offering aesthetic flexibility for applications where appearance matters.
Virgin PET foam or recycled PET foam

Virgin PET foam
Made from virgin PET resin, it boasts higher strength, uniformity, and consistency, making it suitable for applications with extremely high performance requirements.

Recycled PET foam
Recycled PET foam utilizes waste PET materials, regenerating them through a recycling process. It offers lower costs and a smaller environmental footprint, making it suitable for fields with lower strength requirements and a focus on environmental protection and sustainability.
