Polyreflex polypropylene construction honeycomb panels are typically 15mm thick or more, featuring an upgraded structure compared to standard PP honeycomb panels. This design provides enhanced stability, superior strength, and excellent physical properties. The panels consist of four layers of polypropylene, including two flat surfaces and a unique double-layer honeycomb core. The result is an ultra-thick, lightweight plastic honeycomb board, specifically engineered for use in construction applications.

These ultra-thick honeycomb panels are widely used in China, particularly as backboards for porcelain or quartz countertops. Their combination of light weight and strength makes them ideal for providing support and stability. Additionally, their excellent insulation properties make them a great choice for wall panels and partitions.

Beyond their basic form as bare panels, these honeycomb panels are often laminated with various surface materials to enhance functionality, such as non-woven fabrics or leather. They are also gaining popularity in the automotive industry, where they are used for applications like the rear seat backboards and interior walls and ceilings of vans.
