Description

Glossy gelcoat FRP skin PET foam sandwich panel is a high-performance composite panel that perfectly combines a smooth, glossy gelcoat FRP skin with a lightweight closed-cell PET foam core.
- The FRP skin surface features a special gelcoat coating, resulting in an extremely smooth, aesthetically pleasing surface while enhancing the panel’s durability and resistance to environmental damage.
- The closed-cell PET foam core offers excellent lightweight properties, dimensional stability, and moisture resistance.
Product Features
- Aesthetic Appeal
The glossy surface gives the panel a clean, high-end look, making it particularly suitable for applications with high aesthetic requirements.
- Lightweight Structure
The PET foam core significantly reduces panel weight while maintaining good structural performance.
- High Strength and Stiffness
