Polypropylene honeycomb core exhibits a unique cell structure. The core has 3 orientations vs. the 2 orientations common with other honeycomb, making its properties more uniform. Each cell has a tubular form and is inherently stable. Polypropylene honeycomb is supplied with or without a non-woven polyester veil for better bonding. It is also supplied with or without a film barrier under the polyester veil to limit the amount of resin consumption. The honeycomb is thermoformable, high strength and low weight. Other properties include resistance to corrosion, fungi, moisture and chemical. Polypropylene honeycombs are energy absorbing as well as sound and vibration dampening. And finally, they benefit from being recyclable.
