1. Description:


PTFE gaskets have significant advantages in terms of friction coefficient and electrical insulation properties. Its extremely low coefficient of friction reduces energy loss and wear, increasing the efficiency and life of the system. At the same time, its excellent electrical insulation performance and high electrical insulation angle enable PTFE gaskets to provide reliable electrical insulation protection and ensure the safety and reliability of the circuit. These characteristics make PTFE gaskets the preferred sealing material in many applications.

PTFE gasket has unique characteristics and advantages in terms of friction coefficient and electrical insulation performance.


First, PTFE gaskets have an extremely low coefficient of friction. The smooth, non-stick properties of its surface allow for minimal friction when in contact with other materials. This means that the PTFE gasket provides excellent non-stick properties, reducing friction and wear when in contact with the fitting. Compared with gaskets of other materials, PTFE gaskets can reduce energy loss and heat generation, thereby improving the efficiency and performance of the system.


Second, PTFE gaskets have excellent electrical insulation properties. PTFE is an excellent insulating material, which can effectively isolate current and prevent current leakage and arc occurrence. PTFE gaskets are widely used in electronic and electrical equipment to isolate and protect circuits. Its electrical insulation properties enable PTFE gaskets to withstand high voltage and high electric field strength, ensuring the stability and safety of the circuit.


In addition, PTFE gaskets also have excellent electrical insulation angles. Electrical insulation angle refers to the angle at which a material begins to generate electric shock or breakdown under high voltage. PTFE gasket has a high electrical insulation angle, which means it can maintain insulation performance at higher voltages, delaying the occurrence of electric shock and breakdown. This makes PTFE gaskets of great significance in applications requiring high electrical insulation capabilities, such as high-voltage power equipment and electrical insulation systems.
