Made In China Different Types Oil Seal FKM VMQ PTFE Material Seals

　　Operating machinery in extremely low-temperature environments presents
unique challenges, particularly when it comes to selecting the appropriate
sealing materials. Seals used in these conditions must be able to withstand the
cold temperatures without compromising their functionality. In this article, we
will explore the sealing materials that are commonly considered suitable for
operating at extremely low temperatures, providing insights into their
characteristics and applications.

　　1. Fluorocarbon Rubber (FKM):

　　Fluorocarbon rubber, commonly known as FKM, is a popular sealing material
known for its excellent resistance to high temperatures and chemicals. However,
it also exhibits good low-temperature properties, making it suitable for use in
extremely cold environments. FKM seals can maintain their flexibility and
sealing integrity even at temperatures as low as -20°C, and in some cases,
even lower. This makes FKM a preferred choice for applications that require
both high-temperature and low-temperature resistance, such as automotive, and
oil and gas industries.

　　2. Silicone Rubber (VMQ):

　　Silicone rubber, or VMQ (vinyl methyl silicone), is another sealing
material that exhibits good low-temperature properties. Silicone rubber can
typically withstand temperatures as low as -60°C. However, some sources
suggest that it can function at temperatures down to -70°C to -55°C. This
makes them suitable for applications in refrigeration, cold storage, and
automotive industries, where temperatures can reach sub-zero levels.

　　3. Polytetrafluoroethylene (PTFE):

　　Polytetrafluoroethylene, commonly known as PTFE, is a versatile sealing
material known for its excellent chemical resistance and low friction
properties. PTFE seals can typically withstand temperatures as low as -65°C
without significant loss of functionality. This makes them suitable for
applications in chemical processing, food processing, and pharmaceutical
industries, where low temperatures are encountered.

　　Selecting the appropriate sealing material for operating at extremely low
temperatures is crucial to ensure the reliability and performance of machinery
and equipment. It is important to consider the specific temperature
requirements and application conditions when choosing the sealing material to
ensure optimal performance and longevity of the seals.
