FRP Sandwich Panel — PET Core

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.

Structure

How the Structure Improves Panel Performance

  • Reduces panel weight through a lightweight PET core structure, making handling and installation easier while maintaining overall panel performance
  • Improves structural stability with a rigid PET core layer that supports the FRP skins and helps the panel resist deformation
  • Withstands long-term weathering, with durable FRP gelcoat skins providing protection against UV exposure, moisture, and outdoor conditions

Why PET Core

PET Core provides a practical balance of lightweight design, structural performance, and sustainability, making it suitable for applications where weight efficiency and environmental considerations are important.

Applications

Suitable for marine interiors, modular buildings, vehicle interiors, and other applications requiring lightweight and durable sandwich panel solutions.

FAQ

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.
