The felt (hair) is intended for uses listed below and for similar applications:

H-26-S - For insulation where the temperature will not exceed 120°F for cushioning, packing, and padding, and crating of greater than one-time use. Vibration mountings and dust H-26-R shields. H-34-S - For cushioning, packing, padding, and shielding where moderate and strength and and abrasion resistance are required. Vibration and shock mounts for long-term operation. H-34-R Ammunition components, when class N. Filter elements. H-43-S - For cushioning, packing, padding, and shielding where high and strength and abrasion r and resistance are required. Vibration end shock mounts for long - term operation and H-43-R moderate loading. Ammunition components when class N. Polishing blocks, wheels and pads, wiper, applicators, and filter elements. H-56-S - For cushioning, packing, padding, and shielding where unusual and strength, hardness, and abrasion resistance are required. H-56-R Vibration and shock mounts for heavy loading and high frequency. Ammunition components when class N. Heavy-duty polishing blocks, wheels, and pads. Wipers, applicators, and filters.
