Introducing the PP honeycomb panels — a cutting-edge composite material that redefines strength and lightness. These panels boast a unique design, with continuous glass fiber-reinforced PP tapes fused in a crosswise pattern as the outer layers and a PP honeycomb core. This innovative combination integrates the unbeatable strength of glass fibers with the featherweight nature of PP honeycomb, resulting in a panel that’s both incredibly strong and ultra-lightweight.
PP honeycomb panels are a revolutionary composite material combining exceptional strength, stiffness, and remarkable lightness. Their honeycomb-like core, made of polypropylene (PP), offers durability without extra weight, ideal for robust, lightweight applications. Reinforced with crosswise glass fiber-PP tapes, these panels provide unparalleled structural integrity, ultra-lightweight properties, and high durability.
In addition to their structural advantages, PP honeycomb panels also exhibit excellent surface properties. As a non-polar material, PP has poor surface wettability, which means it doesn’t easily absorb moisture or other polar substances. This characteristic contributes to the panels’ good weather and heat resistance, as well as their excellent processing and molding performance.
Overall, PP honeycomb panels are a versatile and high-performance material that offers a perfect blend of strength, lightness, and durability.
Taking the 12mm PP honeycomb panel used for scaffold boards as an example, it has an areal density of 4.52 kg/m², while the Marine Plywood of the same specification has an areal density of 8.58 kg/m². The areal density of the former is reduced by 47% compared to the latter. For weight comparison of boards with more thickness options, please refer to our Scaffold Boards.
The high strength of PP honeycomb panels is mainly demonstrated in three aspects: bending strength, compressive strength, and impact strength. For bending strength, we can conduct tests according to ISO 14125 or ASTM C393-00 standards. For compressive strength, we generally adopt the GB/T 1453-2005 standard. Regarding impact testing, our test criteria are as follows: falling ball diameter of 127 mm, impact weight of 4.5 kg, impact height of 1810 mm, and type of impact as a direct hit. PP honeycomb panels exhibit high impact strength, and our specially designed PP honeycomb panels can even be used as floorboards for horse trailers or trucks, capable of bearing the weight of horses as well as the impact force from their hooves.
PP honeycomb panels exhibit excellent high and low temperature resistance. Under experimental conditions of 85°C for 24 hours and -40°C for 24 hours, they do not exhibit any abnormal phenomena such as cracking, delamination, deformation, sticking, discoloration, etc. After returning to room temperature, there are no significant changes observed in their key performance indicators, including bending strength.

By incorporating light-aging and thermal stabilizers, PP honeycomb panels can meet a service life of 7 to 10 years in outdoor environments. For panels with specific lifespan requirements, such as those used as backsheets in photovoltaic applications, through the use of specialized formulations, they can even achieve a service life of up to 25 years.
PP honeycomb panels have emerged as a go-to material across various industries due to their unique blend of properties. Here’s a closer look at their key application areas:
In essence, PP honeycomb panels are versatile and robust, making them an ideal choice for a multitude of applications across different industries. Their unique blend of properties ensures that they meet the diverse needs of modern transportation, automotive, logistics, and customization requirements.
During the thermal lamination process, the thickness of our PP Honeycomb Panels is formed in one go. By finely tuning temperature, pressure, speed, tapes, and honeycomb cores, we ensure exceptional thickness control. Furthermore, the thermal lamination ensures superior panel bonding, guaranteeing high quality stability. We also employ numerically controlled cutting machines to achieve extremely high precision in length, width, and other dimensions, catering to customers with demanding specifications.
PP honeycomb panels — the ultimate choice for strength, lightness, and environmental responsibility.
