TOPOLO provides excellent performance thermoplastic honeycomb core and honeycomb composite panel solution services.
What is Polypropylene Honeycomb?
Polypropylene (PP) is a thermoplastic polymer made from propylene through the polymerization reaction. The cells of polypropylene (PP) honeycomb core are mainly round, and they are fused together rather than glued together. These cells join together to form a stable structure. The density of the honeycomb core changes with the change of cell size. The smaller the cell size, the higher the density and strength.

Advantages
- Compression-resistant and impact-resistant
PP honeycomb structure effectively absorbs external forces, thereby greatly reducing damage caused by impacts and collisions. - Lightweight
PP honeycomb core density is low, and it can achieve the same effect with less mass than other materials. - Water-resistant and corrosion-resistant
Due to the characteristics of its thermoplastic raw material, it can be used for a long time in environments with high water content and strong corrosion. - Environmental friendly
Polypropylene thermoplastic resin is energy efficient, 100% recyclable and contains no VOCs and formaldehyde during processing.
To Add Non-woven Fabric or Not?
Polypropylene honeycomb core is available with or without non-woven fabric for better bonding. Typically when using thermal lamination, non-woven fabrics are not required. When using adhesive, non-woven fabric needs to be added to the bottom layer. To reduce adhesive consumption a film barrier layer is added underneath the non-woven fabric.
