UL PTFE Seal Gasket CNC Machining Bushing For High Voltage Connector

PTFE CNC Machine precision bearing High voltage connector Precision insulator custom virgin PTFE natural color




We are a factory professional processing PTFE PCTFE PVDF PFA PI PAI PEEK PEI PPS POM ABS PC PMMA Nylon engineering plastic parts.

PTFE insulators are used primarily because of their superior dielectric properties especially at high radar and microwave
frequencies. PTFE also works in a wide temperature from –180°C to +260°C.


PTFE seals are a widely used high-pressure sealing material with several unique properties. First, it is chemically inert and stable in extreme environments. Secondly, PTFE material has good high temperature resistance and can be used under high temperature conditions for a long time without failure. In addition, it has excellent wear and corrosion resistance for stability in harsh working environments.


In addition to these properties, PTFE seals also have good fire performance. PTFE material will not burn at high temperature and will not produce toxic gas. Therefore, it is widely used in fireproof materials, such as firewalls, fire doors and fire windows, etc.


PTFE seals also have good corrosion resistance and can resist the erosion of various chemicals. Therefore, it is widely used in chemical industry and petroleum industry. In addition, it can be used in food processing and medical equipment because it is non-toxic and odorless to food and medicine, and has excellent antibacterial properties.

3 .Processing technology

Machining accuracy has a crucial influence on the performance and life of PTFE seals. The machining process of PTFE seals is relatively complicated, and special processes and tools are required to ensure the accuracy and quality of the product.


In the machining process of PTFE seals, it is first necessary to select appropriate processing equipment and tools. PTFE material is a special polymer material, and its processing requires the use of high-precision machine tools and cutting tools to ensure the accuracy and surface quality of the product.


Secondly, in the machining process of PTFE seals, it is necessary to strictly control the machining parameters, such as cutting speed, feed speed, tool selection, etc. The control of these parameters can effectively reduce problems such as material deformation and poor surface quality, thereby improving the processing accuracy and consistency of products.


Finally, during the machining process of PTFE seals, strict quality inspection and testing are required to ensure that the performance and precision of the product meet the requirements. Commonly used detection methods include dimensional measurement, surface roughness measurement, sealing performance test, etc.
