Parts which require minimum weight often employ Nomex® honeycomb sandwich cores. #1562 and #2562 are .210" cut thickness with a 3/16" overexpanded cell. #1562 is 1.8 lb/cu ft. density and #2562 is 3.0 lb/cu ft. Both are quite flexible due to the overexpanded cell structure, making them perfect for use in tight radius curves. All of our resins will bond well to the phenolic coated honeycomb, reducing peel.
