Explore different levels to meet diverse needs-Refer FKM Materials

With the continuous advancement of industrial technology, FKM (fluorine rubber), as an excellent sealing material, has gradually become one of the first choices in many fields. In the FKM material family, different levels of materials exhibit their own unique performance characteristics, providing diverse solutions for a wide range of application scenarios.

1. FKM70

This grade, also known as Viton A, is known for its fluorine content of approximately 66%. FKM70 has excellent heat and oil resistance, making it ideal for use in areas such as the automotive industry. Its superior elasticity and durability also make it popular in power transmission systems and seal manufacturing.

2. FKM75

Another common choice is FKM75, also a Viton A version. Compared with FKM70, FKM75 has a higher fluorine content (approximately 70%), thus showing better heat resistance and oil resistance. This makes FKM75 outstanding in high temperature environments and oil seal applications.

3. FKM80

FKM80, labeled as Viton B, has a fluorine content of about 76%. It has strong acid and alkali resistance and is widely used in the chemical industry. FKM80 exhibits excellent stability and durability when faced with harsh chemical environments.

4. FKM85

As the representative of Viton GH, FKM85 has a fluorine content of up to 85%, which brings it excellent chemical resistance. Especially in acidic media, FKM85 shows outstanding corrosion resistance, making it an ideal choice for some special industries such as chemical and medical device manufacturing.

5. FKM90

FKM90, known as Viton ETP, stands out with a fluorine content of approximately 90%. Its extremely high chemical resistance makes FKM90 suitable for applications under extreme conditions, such as those in the aerospace sector and in highly corrosive atmospheres.

6. FKM GLT AND GFLT

FKM GLT and FKM GFLT are two different grades of FKM (fluorine rubber) materials. They have different characteristics and application fields respectively.

FKM GLT

  • Definition: FKM GLT is a fluorine rubber, GLT stands for Low Temperature.
  • Properties: This material has a low glass transition temperature (Tg) and therefore remains elastic and soft in low temperature environments. It typically exhibits excellent resistance to oil, chemicals and heat.
  • Applications: FKM GLT is commonly used in cold climate sealing applications such as aerospace, automotive and industrial equipment.

FKM GFLT

  • Definition: FKM GFLT represents a fluorine rubber, where GFLT stands for General Low Temperature.
  • Features: Similar to FKM GLT, FKM GFLT also has good low-temperature elasticity and remains soft in low-temperature environments. In addition, it exhibits superior oil, chemical and heat resistance.
  • Applications: FKM GFLT is suitable for a variety of applications that require sealing performance in low temperature environments, such as hydraulic systems, chemical industry and food processing equipment.

Overall, the different grades of FKM materials provide engineers and designers with more options to meet the needs of different industries and application areas. In the future, with the continuous advancement of material science, FKM materials are expected to continue to innovate and bring more advanced sealing solutions to various industries.
