Chemical Resistance Modified PTFE , Waterproof PTFE Seal Gasket
This part is made of Modified PTFE and CNC machined.
The mixed material of PTFE and glass fiber, also known as PTFE glass fiber composite material or PTFE glass fiber reinforced material, is an engineering plastic with excellent performance. The material combines the advantages of PTFE and fiberglass with many advantages.
First of all, PTFE+glass fiber material has excellent high temperature resistance. PTFE itself is an excellent high-temperature material, capable of withstanding temperatures up to 260°C. After adding glass fiber, its high temperature resistance is more excellent. This makes PTFE+glass fiber materials very suitable for use in high temperature environments, such as in automotive engine compartments and aerospace fields.
Secondly, PTFE+glass fiber material has excellent mechanical properties. Glass fiber is a high-strength material that can enhance the mechanical strength and hardness of PTFE, thereby improving the wear resistance and durability of the material. PTFE+glass fiber material has excellent mechanical properties and can be used to manufacture various mechanical parts such as seals, bearings, gears, and hubs.
In addition, PTFE+glass fiber material also has good chemical stability. PTFE is a chemically inert material that is resistant to chemical corrosion such as acids, alkalis, and solvents. After adding glass fiber, its chemical stability is stronger, and it can maintain the performance of the material in harsh chemical environments. Therefore, PTFE+glass fiber materials are widely used in chemical, medical and food processing and other fields.
Finally, PTFE+glass fiber materials also have good electrical insulation properties and radiation resistance, so they are widely used in the fields of electronics, communications and aerospace.

PTFE (polytetrafluoroethylene) is a well-known polymer with excellent properties such as high-temperature resistance, low friction, and excellent chemical stability. PTFE is widely used in various industries such as aerospace, automotive, and chemical processing. However, PTFE has some limitations, such as low strength and wear resistance. To overcome these limitations, PTFE can be reinforced with glass fiber to form a composite material.
PTFE + glass fiber composite material, also known as PTFE glass fiber reinforced material, is a high-performance engineering plastic that combines the benefits of PTFE and glass fiber. The addition of glass fiber to PTFE results in improved mechanical and tribological properties.
One of the primary advantages of PTFE + glass fiber is its high-temperature resistance. PTFE itself can withstand temperatures up to 260°C, and the addition of glass fiber further enhances its high-temperature properties. This makes it suitable for use in high-temperature applications, such as automotive engine compartments and aerospace.
Another advantage of PTFE + glass fiber is its excellent mechanical properties. Glass fiber is a high-strength material that can enhance the mechanical strength and hardness of PTFE, resulting in improved wear resistance and durability. PTFE + glass fiber is ideal for manufacturing various mechanical parts such as bearings, gears, and hubs.
PTFE + glass fiber also has excellent chemical stability. PTFE is chemically inert and can resist acids, alkalis, and solvents. The addition of glass fiber further improves its chemical stability, making it suitable for use in harsh chemical environments. PTFE + glass fiber is widely used in industries such as chemical processing, medical, and food processing.
PTFE + glass fiber is also an excellent electrical insulator and can resist radiation. This makes it ideal for use in electronics, communication, and aerospace applications.
In summary, PTFE + glass fiber is a high-performance engineering plastic with excellent properties. It offers high-temperature resistance, excellent mechanical properties, chemical stability, electrical insulation, and radiation resistance. The addition of glass fiber to PTFE enhances its mechanical and tribological properties, making it suitable for use in various applications. PTFE + glass fiber is widely used in industries such as aerospace, automotive, chemical processing, and electronics.
