About Cable Rubber Seals
Cable rubber seals are highly resistant to high temperatures and can work for long periods in extremely high-temperature environments. The PTFE seals we use are excellent electrical insulators and can work stably in high-voltage environments. This characteristic makes PTFE seals widely used in electronic and electrical fields.
Why use PTFE for Cable Rubber Seals?
Polytetrafluoroethylene in recent years has been listed as the most ideal insulating material for cables and wires, the reason for this is that polytetrafluoroethylene itself has low loss, friction resistance, aging resistance, dielectric constant, thermal stability, and a certain degree of flexibility and so on. It makes the time when the cable is in use greatly increased, and reduces a lot of labor and material losses.
