1. Description:


PTFE baffle ring gaskets are highly regarded for their exceptional sealing performance and unique characteristics. Here's a detailed description of PTFE baffle ring gaskets, focusing on the dimensions of friction coefficient, sealing performance parameters, and application market:

Friction Coefficient:

PTFE baffle ring gaskets exhibit an extremely low friction coefficient, which allows for smooth installation and removal. This property minimizes frictional losses and ensures easy assembly, disassembly, and maintenance of the gasket. The low friction coefficient also helps in reducing wear and tear, extending the gasket's lifespan. Compared to traditional gaskets, PTFE baffle ring gaskets offer improved ease of use and enhanced efficiency in sealing applications.

2.Sealing Performance Parameters:


Pressure Resistance: PTFE baffle ring gaskets are capable of sealing under high-pressure conditions. They maintain their integrity and prevent leaks, even when exposed to significant pressure differentials.

Chemical Resistance: PTFE has excellent resistance to various chemicals, acids, and corrosive substances. This makes PTFE baffle ring gaskets suitable for applications involving aggressive media, such as in chemical processing plants or industrial settings.

Temperature Resistance: PTFE gaskets exhibit exceptional thermal stability, allowing them to perform reliably across a wide range of temperatures, from extremely low to high temperatures. They can withstand thermal cycling without compromising their sealing capabilities.
Compression and Recovery: PTFE baffle ring gaskets offer excellent compression and recovery properties, ensuring a tight seal even after repeated compression and relaxation cycles. This property allows for consistent sealing performance over an extended period.


3.Application :

PTFE baffle ring gaskets find extensive use in various industries and applications, including:

Chemical Processing: PTFE gaskets are commonly employed in chemical processing plants, where they effectively seal flanges, pumps, valves, and other equipment. Their resistance to aggressive chemicals ensures reliable and leak-free operation.

Oil and Gas Industry: PTFE baffle ring gaskets are widely utilized in the oil and gas sector for sealing applications involving hydrocarbons, acids, and other corrosive substances. They provide a secure and reliable seal, even in challenging operating conditions.

Pharmaceutical and Food Processing: PTFE gaskets are highly suitable for pharmaceutical and food processing applications due to their excellent chemical inertness and non-contaminating properties. They ensure a hygienic and safe sealing environment.

Power Generation: PTFE baffle ring gaskets are utilized in power plants for sealing applications involving steam, gases, and chemicals. Their resistance to high temperatures and corrosive substances ensures efficient sealing in critical power generation equipment.




PTFE (polytetrafluoroethylene) is a high-performance engineering plastic that is widely used in various high-temperature environments. As a high-performance sealing material, PTFE seal needs to be able to withstand extreme high temperature environments, so its high temperature resistance is very important.


First of all, PTFE seal has extremely high temperature resistance. PTFE has a high melting point and can still have good performance at a high temperature of 260°C, and can even withstand temperatures as high as 300°C in a short period of time. In contrast, many other sealing materials will lose their sealing performance at high temperatures, or even melt or burn, while PTFE seals can maintain good sealing performance in extremely high-temperature environments.


Secondly, PTFE seal has excellent chemical stability. PTFE is extremely chemically inert and can resist the erosion of most chemical substances, including acids, alkalis, organics, etc. Therefore, PTFE seal can be used for a long time in various corrosive media such as strong acid, strong alkali and organic matter without being corroded and damaged.


In addition, PTFE seal also has good mechanical properties. Although the mechanical strength of PTFE is not high, PTFE seal can improve its mechanical properties by adding fillers or reinforcing fibers. For example, mixing PTFE with fiberglass increases its mechanical strength and stiffness, which increases its durability and load-bearing capacity.


The sealing performance of PTFE seal is also very outstanding. PTFE is an excellent sealing material with a low coefficient of friction and good sealing performance, and can maintain stable sealing performance under high temperature and high pressure conditions. In addition, PTFE also has extremely high aging resistance, can maintain stable sealing performance for a long time, and is not easy to harden or deform.
