A lightweight, recyclable core option for projects prioritizing sustainability and weight reduction.
Product Overview
SKD FRP Sandwich Panels with PET Core combine a weather-resistant FRP gelcoat outer skin, a PET rigid foam core, and an FRP inner skin — a structure that pairs good structural support with moderate insulation performance, in a lightweight and recyclable material.
PET Core is a practical choice for projects where sustainability and weight reduction are priorities, without sacrificing the structural support needed for panel applications.

How the Structure Improves Panel Performance

Product Specifications
Specification | Value |
Overall Thickness | Custom, made to order |
Panel Width | Sized to standard container dimensions — panels exceeding container dimensions cannot be shipped |
Core Density | To be confirmed |
Warranty | 10–15 years, consistent with FRP Gelcoat Panels |
Core Material | PET rigid foam |
Skin Material | FRP gelcoat (outer) + FRP (inner) / |
Panel width is determined by standard container dimensions for shipping purposes. Panels wider than standard container dimensions cannot be transported and are therefore not available. Contact our team to confirm the maximum width for your specific container type and shipping route.
Why PET Core
With its lightweight and recyclable properties, the PET Core Sandwich Panel is well suited for applications prioritizing sustainability and weight reduction, including:Modular Building Panels, Transportation Vehicle Interior Panels, Marine Interior Components, and other applications where reducing weight and environmental impact is a priority alongside structural performance.

A: PET Core is a lightweight, recyclable option offering good structural support with moderate insulation — a good fit when sustainability and weight reduction are priorities. PU and XPS Core are optimized specifically for thermal insulation performance. Contact our team to discuss which fits your project’s requirements.
A: Yes. Panel thickness is made to order based on your project’s structural and performance requirements. Contact our team to discuss the right thickness for your application.
A: Both. PET Core’s balance of light weight and good structural support makes it suitable for structural wall panels as well as interior paneling applications — such as vehicle and marine interiors — where a rigid yet lightweight material is needed.
A: Yes. The FRP gelcoat skins resist moisture and corrosion, and PET itself is not prone to water absorption, making PET Core panels a practical choice for marine interior components and other humid environments.
A: PET (polyethylene terephthalate) is a widely recyclable thermoplastic material, which is why PET Core is often chosen for projects with sustainability goals. Contact our team if you need documentation to support specific sustainability or recyclability requirements for your project.
