In an era where green manufacturing and material science are deeply intertwined, we are proud to announce the successful development and mass production of our next-generation PET Foam Sandwich Panel. This product represents another major technological breakthrough for our company in the field of Continuous Fiber Reinforced Thermoplastic Composites (CFRTP), delivering a superior solution that combines extreme lightweight properties, ultra-high strength, and full lifecycle sustainability for the transportation, construction, and industrial sectors.
Our PET Foam Sandwich Panel is manufactured using advanced continuous roll-to-roll hot melt lamination technology, utilizing absolutely no adhesives throughout the entire process to ensure true green manufacturing. Its unique three-layer structure delivers unparalleled performance:
High-Performance Skins: Made from our proprietary Continuous Fiber Reinforced Thermoplastic (CFRT) composites. The matrix can be customized with either Polypropylene (PP) or Polyethylene Terephthalate (PET), providing exceptional tensile strength and impact toughness through continuous fiber reinforcement.
Lightweight Core: The middle layer consists of high-density PET foam. As a closed-cell thermoplastic foam, it is extremely lightweight while offering excellent compressive strength, thermal insulation, soundproofing capabilities, and an exceptionally low water absorption rate.
This all-thermoplastic sandwich structure, combining the strengths of both layers, breaks the traditional bottleneck where stiffness and toughness are difficult to achieve simultaneously, realizing a performance leap where 1+1 > 2.
1. Extreme Lightweight for Significant Efficiency Gains
Compared to traditional metal sheets, fiberglass (FRP), or plywood, our PET Foam Sandwich Panels have an extremely low density, achieving substantial weight reduction. In logistics vehicles, this translates to lower fuel/energy consumption and higher payload capacity—truly helping customers "carry more while running efficiently."
2. High Strength-to-Weight Ratio & Superior Durability
Despite being incredibly light, the CFRT skins give the panel specific strength comparable to, or even surpassing, traditional steel. It is corrosion-resistant, acid/alkali resistant, and rust-proof. Unlike traditional fiberglass, it will not age or powder over time, easily withstanding harsh outdoor environments and frequent mechanical impacts, significantly extending product lifespan.
3. Eco-Friendly & 100% Recyclable
This is one of our core competitive advantages. From the PP/PET skin matrices to the PET foam core, the entire panel is composed of thermoplastic resins. This means it can be 100% recycled at the end of its life, melted down and re-granulated into raw materials for other industrial applications. It perfectly aligns with global carbon neutrality goals and the trends of the circular economy.
4. Excellent Processing & Functional Properties
The panels offer outstanding thermal insulation and noise reduction. They feature a smooth, aesthetically pleasing surface that is easy to clean. Furthermore, thanks to the hot-melt bonding process, the panels support secondary thermoforming, allowing for the customization of complex curves and structures based on client needs.
With its excellent comprehensive performance, this PET Foam Sandwich Panel is revolutionizing material substitution across multiple industries:
Commercial & Logistics Vehicles: Perfectly suited for the side walls, roofs, and floors of dry freight vans and refrigerated trucks. It serves as an excellent replacement for traditional XPS foam core panels or FRP sandwich panels, offering better waterproofing and much easier, more efficient assembly.
RVs & Specialty Vehicles: Ideal for RV walls, floors, and roofs. Its superior insulation properties and lightweight nature significantly enhance living comfort and driving economy.
New Energy & Industrial Equipment: Can be used for photovoltaic backplanes, wind turbine blade cores, and various industrial equipment partitions or protective covers requiring lightweight and high rigidity.
Green Buildings & Prefabricated Housing: Suitable for wall panels, roofing, and interior partitions in modular homes, providing safe, eco-friendly, and fast-construction building solutions.
We are dedicated to exploring the infinite possibilities of material science. The successful development of our new PET Foam Sandwich Panel marks another solid step forward in our journey toward sustainable lightweight materials. Moving forward, we will continue to be innovation-driven, providing global clients with even more competitive composite material solutions!
