Poly Core

PP Polypropylene Honeycomb

PP 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.

PP 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.

PP Honeycomb provides properties used in many composite sandwich structures that require core shear and compression along with adhesion performance. The unique cell structure, the use of a high impact copolymer PP and unique material processing contribute to its attractive performance levels.
