ZHM Pneumatic Seal Pneumatic Cylinder Seal
♠Description-ZHM Pneumatic Seal
ZHM Pneumatic Seal used for reciprocating cylinder rods for sealing and dust proofing, most of which use FKM/VITON and silicone material. The thickened sealing lip is specifically designed for reciprocating cylinder rod sealing applications. Besides, a pneumatic seal’s sealing orientation can be internal as with a rod seal, external as with a piston, symmetrical, or axial. With internal pneumatic seals, a housing bore surrounds the seal and the sealing lip touches the shaft. In addition, this seal requires very little lubricant.

♣Advantage
● The electrical properties, PTFE is a highly non-polar material, with extremely excellent dielectric properties, prominently when more than 0 ℃, dielectric properties and does not affect the frequency with temperature, humidity and are not subject to influence of corrosive gas . PTFE volume resistivity and surface resistivity is the highest of all plastics, even after prolonged immersion in water, it will not drop significantly, at 100% relative humidity of the air, the surface resistivity remains unchanged. Crystallinity of PTFE at 50% to 80%, the dielectric strength is almost independent of the degree of crystallinity, and having the lowest dielectric constant. PTFE excellent arc resistance.
