Polypropylene Honeycomb Core
PP honeycomb core is a thermoplastic material with a circular open-cell design. Its density ranges from 58 to 105 kg/m³. It is a plastic sheet material with excellent bending strength. Even though it’s very lightweight, it has great bending strength. This gives it a high strength-to-weight ratio. This plastic sheet material can be laminated with non-woven polyester fiber fabric. It features heat resistance, corrosion resistance, moisture resistance, and sound insulation properties.

Product Description
PP honeycomb core is a plastic sheet with a circular open-cell design. It is used as the core material for sandwich panels, providing high strength. It’s often used in box truck bodies, RVs, construction, flooring, and marine applications. We offer maximum lengths of 3.2 meters, maximum widths of 1.6 meters, and thicknesses ranging from 5 mm to 200 mm.
Composite Box provides PP honeycomb cores with non-woven polyester fiber facings. These facings improve adhesion and stop adhesive from penetrating. PP honeycomb cores support thermal forming, vacuum infusion, and other processing methods. They are easy to process, ensuring efficient production. We offer a variety of facings for selection.
Advantages
PP honeycomb cores offer numerous advantages, many of which are unmatched by other core materials. Their strong performance comes from their design, how they are made, and the qualities of PP resin.
High Strength
PP honeycomb cores have great bending resistance. They absorb and spread out external forces, which help reduce impact damage. They can withstand significant impacts and bear heavy loads.
Material Efficiency
In the past, nearly all materials were solid. Under the same strength conditions, PP honeycomb cores use less material. They offer better lightweight performance under higher compressive strength.
Corrosion Resistance:
PP honeycomb cores have a long service life, thanks to their excellent corrosion resistance. They can withstand the corrosion of acids, alkalis, and salts in humid environments while maintaining structural stability. Therefore, they are suitable for applications in low-temperature, marine, and chemical environments.
Recyclability:
PP honeycomb cores are recyclable materials, as polypropylene has a 100% recyclable property. This significantly reduces resource consumption and carbon emissions. PP honeycomb cores are non-toxic and harmless during the recycling process, making them a popular recyclable material.
