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.
- 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.
Application
PP honeycomb core is widely used in construction, automobile, interior decoration and other fields as filling material. Such as dry truck body, car trunk partition, wall partition, yacht, purifier, waterproof table, etc.
PP Honeycomb Core Composite Materials
The Polypropylene honeycomb core and the reinforcing sheet are compounded together to form a solid honeycomb composite panel. Among them, the fiberglass honeycomb composite panel has become mainstream, and it is more and more widely used in vehicles, buildings, ships, household appliances, etc.
