High Quality NBR FKM VMQ PU PTFE HNBR FVMQ Material Oil Seal Shaft Seals

　　Oil seals also known as shaft seals, are essential components in various
types of machinery. They are primarily used to seal the openings between
stationary and moving components in mechanical equipment. The materials used to
manufacture oil seals vary based on the application and environmental
conditions. Here are some of the most commonly used materials:

　　Nitrile (Buna): Nitrile is the most widely used elastomer in sealing.
Nitrile oil seals have great resistance to petroleum oils and fuels, mineral
oils and greases, hydraulic fluids, water, steam, and alcohol. They combine
excellent resistance to petroleum-based oils and fuels, silicone greases,
hydraulic fluids, water, and alcohols.

　　Fluororubber (FKM): Fluororubber oil seals feature excellent resistance to
petroleum products and solvents. They have good high temperature and low
compression set characteristics. They are suited for use with wide chemical
exposure situations and for hard vacuum service.

　　Silicone (VMQ): Silicone oil seals have a high lubricant absorption
capacity. It minimizes wear and friction in some applications.

　　Polyacrylate: Polyacrylate has better heat resistance than Nitrile. It
works well in high surface speed oil seals.

　　Polyurethane: Polyurethane is an excellent material with high abrasion
resistance characteristics and high tensile strength. Polyurethane oil seals
are used in high pressure hydraulic systems where highly stressed parts are
subject to wear.

　　Fluorosilicone (FVMQ): This material combines the good high and low
temperature stability of silicone with the fuel, oil, and solvent resistance of
fluorocarbon.

　　Highly Saturated Nitrile (HSN, HNBR): Oil seals made from highly saturated
nitrile have excellent resistance to petroleum oils and sour gas.

　　Polytetrafluoroethylene (PTFE): PTFE is a tough, chemically inert polymer
possessing an incredible working range.

　　Understanding the differences between these materials is essential when
selecting the right seal for your application. While all these materials serve
the same general purpose of preventing leakage and contamination, their
specific applications vary based on the nature of the machinery they are used
in.
