Qingdao Kaifeier has completed a bulk delivery of high-performance FRP PU sandwich panels to Baola, a professional cold chain box manufacturer. The insulated panels have been counted, palletized and loaded for shipment to support the production of refrigerated vehicle box bodies.

These rigid polyurethane sandwich panels serve as core cladding materials for cold chain equipment. Featuring closed-cell PU foam core, the panels deliver low thermal conductivity and stable insulation performance. They combine high structural rigidity with light weight, which reduces the overall weight of refrigerated boxes and cuts energy consumption during cold transportation.

Key Advantages of Kaifeier PU Insulated Sandwich Panels

• Customizable thickness and panel width to match different box designs

• High surface flatness, simpler cutting and fast on-site assembly

• Excellent weather resistance for long-term use in refrigerated trucks, insulated cabins and mobile cold units

Strict Quality Control & Stable Supply Capacity

All composite panels are produced on Kaifeier’s automated continuous production line. The internal QC team inspects raw materials, foaming parameters, finished dimensions and insulation performance batch by batch before shipment. Optimized production scheduling and loading workflows guarantee consistent lead times for long-term partners.

Wide Application of FRP-PU Composite Panels

Beyond cold chain refrigerated boxes, Kaifeier PU sandwich panels are widely adopted for camper vans, mobile food trucks, modular cabins and cold room construction. We provide one-stop composite panel solutions for manufacturers who need reliable thermal insulation and structural panels.

Kaifeier will continue to invest in polyurethane composite material development, upgrade foam formulation and panel processing technology. With stable production capacity and consistent quality, we aim to support more cold-chain and special vehicle manufacturers in China and overseas.
