This packing is a multi-yarns packing. The corners of packing are made of aramid fiber yarns impregnated with PTFE, the friction faces are made of PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure PTFE.
Nomex Fiber Packing braided from high quality Dupont Spun nomex yarns with PTFE impregnated and lubricant additive, high cross-sectional density and structural strength, good sliding characteristic, gentle on shaft. Compared to kevlar, not hurt shaft, good idea for food industries.
