RPTFE C-Graphite vs. RTFE Glass Filled
What's the Difference?
RPTFE C-Graphite and RTFE Glass Filled are both types of filled PTFE materials commonly used in sealing applications. RPTFE C-Graphite contains a combination of carbon and graphite fillers, which provide enhanced thermal and chemical resistance. On the other hand, RTFE Glass Filled is reinforced with glass fibers, offering improved strength and wear resistance. While RPTFE C-Graphite is better suited for high temperature and corrosive environments, RTFE Glass Filled is ideal for applications requiring higher mechanical performance. Ultimately, the choice between the two materials depends on the specific requirements of the sealing application.

Introduction
When it comes to choosing the right material for sealing applications, two popular options are RPTFE C-Graphite and RTFE Glass Filled. Both materials have unique attributes that make them suitable for different situations. In this article, we will compare the characteristics of these two materials to help you make an informed decision.
Chemical Resistance
RPTFE C-Graphite is known for its excellent chemical resistance, making it a popular choice for applications where exposure to harsh chemicals is a concern. The graphite filler in RPTFE provides additional strength and stability, making it ideal for sealing applications in chemical processing plants and other industries where chemical resistance is crucial. On the other hand, RTFE Glass Filled also offers good chemical resistance, but it may not be as effective as RPTFE C-Graphite in extreme chemical environments.
Temperature Resistance
Both RPTFE C-Graphite and RTFE Glass Filled are designed to withstand high temperatures, making them suitable for applications where heat resistance is a priority. RPTFE C-Graphite can handle temperatures up to 600°F, while RTFE Glass Filled can withstand temperatures up to 500°F. This makes RPTFE C-Graphite the better choice for applications that require higher temperature resistance.
Pressure Resistance
When it comes to pressure resistance, RPTFE C-Graphite is the clear winner. The graphite filler in RPTFE provides added strength and stability, allowing it to withstand higher pressures compared to RTFE Glass Filled. This makes RPTFE C-Graphite a better choice for applications where pressure resistance is a critical factor.
Sealing Performance
Both RPTFE C-Graphite and RTFE Glass Filled offer good sealing performance, but they may perform differently depending on the application. RPTFE C-Graphite is known for its excellent sealing properties, making it a popular choice for demanding sealing applications. RTFE Glass Filled also provides good sealing performance, but it may not be as effective as RPTFE C-Graphite in certain situations.
Cost
When it comes to cost, RTFE Glass Filled is generally more affordable than RPTFE C-Graphite. This makes RTFE Glass Filled a cost-effective option for applications where budget is a concern. However, it is important to consider the overall performance and durability of the material when making a decision based on cost alone.
Conclusion
In conclusion, both RPTFE C-Graphite and RTFE Glass Filled have their own unique attributes that make them suitable for different sealing applications. RPTFE C-Graphite offers excellent chemical resistance, temperature resistance, pressure resistance, and sealing performance, making it a popular choice for demanding applications. On the other hand, RTFE Glass Filled provides good chemical resistance, temperature resistance, and sealing performance at a more affordable cost. Ultimately, the choice between these two materials will depend on the specific requirements of your application.
