Product Description
Open Cell PP Honeycomb Core is a plastic core material. It is made according to the honeycomb bionic principle and has extremely high structural stability.
Due to its light weight, high strength and corrosion resistance, it can replace aluminum honeycomb, paper honeycomb and other core materials in many applications.
PP honeycomb core has a wide range of applications, such as core materials for different sandwich panels, air purifier filters, water saw cutting platforms and yacht body materials, etc.
HolyCore PP honeycomb core can be highly customized and we can provide honeycomb core with different thicknesses, different densities and different sizes. In addition, the honeycomb cores can also be made flame retardant.
Product Advantage
