Description
Polypropylene Honeycomb Core is a plastic core made from polypropylene and comes in an open cell configuration with a layer of non-woven polyester scrim for promoting surface bonding. Polypropylene Honeycomb Core can be used for sandwich panel cores and energy absorption. Plastic Honeycomb has a high strength to weight ratio, is sound dampening, and can be recycled. Most importantly, Plastic Honeycomb sheets are corrosion, fungi, rot, chemical, and moisture resistant.
