Advantages of PP Honeycomb Core

Compared with traditional core materials, PP honeycomb materials have the following advantages:

  • Strong compressive and impact resistance

PP honeycomb absorbs external forces, thus greatly reducing the damage caused by impact and collision. It is widely used in many fields such as automobile bumper and sports protective equipment.

  • Lightweight and material saving

According to the excellent mechanical performance, the PP honeycomb can achieve the same effect with fewer consumables, low cost, and lightweight. It is lightweight, and can greatly reduce the load weight of transport, thereby to a certain extent improving the speed of transport, and reducing the cost of transport. Therefore, it is widely used in the manufacture of yachts, cars, trains, and other means of transport shells, ceilings, partitions, decks, floors, and so on.

  • Sound insulation performance is superior

PP honeycomb can greatly reduce the diffusion of sound transmission, can be used as a series of vehicles, yachts, high-speed vehicles, and other noise of the sound insulation equipment of the basic materials, but also can be used as some of the noise, or high requirements for sound insulation of the building decoration materials.

  • Excellent heat insulation performance

PP honeycomb board has excellent heat insulation performance, which can effectively block heat transmission, and makes the internal temperature relatively stable.

  • Water resistance and strong corrosion resistance

Due to the characteristics of its raw materials, it can be used for a long time in environments with high water content and strong corrosion.

  • Green and environmental protection

Energy-saving, 100% recyclable, VOC, and formaldehyde-free in the processing.

Polypropylene Honeycomb Core with Non-woven Fabric

TOPOLO offers polypropylene honeycomb cores with and without a nonwoven polyester veil. The PP honeycomb core with a non-woven polyester veil also provides a film barrier under the polyester veil, preventing resin from entering the pores during processing, thus ensuring uniformity of mechanical properties while also reducing adhesive consumption.
