Hexcel® HexWeb® HRH-78 - 1/4 - 3.0 Commercial Grade Nomex Honeycomb/Phenolic Resin

Designation: Material-Cell Size (inches)-DensityHexWeb HRH-78 is manufactured from commercial grade aramid paper sheets. A thermosetting adhesive is used to bond these sheets at the nodes, and after expanding, the block is dipped in a phenolic resin. After curing the resin, slices are cut to the desired thickness. Using this process, a wide range of cell sizes, paper thicknesses, and densities can be produced. An OX-Core confiation featuring enhanced formability is available upon request.Features: High strength at low densities; Small cell sizes at low densities; Damage resistant under normal shop use; Formable; Flame resistant; Good bonding surfaces; Good thermal and electrical insulator.Applications: HexWeb HRH-78 was developed by Hexcel to offer most of the characteristics of HexWeb HRH-10 for exclusive use in non-aerospace applications, such as pleasure boats, skis, surfboards, ground antennas, and navy joiner panels.
