Product Features
- The surface of the outermost gel coat FRP is smooth and easy to clean, giving the caravan a beautiful appearance. The color of FRP is customizable and users can choose any color within the RAL color range.
- Using LWRT material as the energy absorption layer can improve the overall impact strength of the panel and reduce damage to the internal core material.
- The performance of the recycled PET foam core is no different from that of virgin PET foam.
- The internal skin CFRT is a lightweight and high-strength thermoplastic composite material with higher compressive resistance than thermosetting FRP sheets.
