AS568-008 Simriz 481 Low Temperature FFKM O-Ring

Simriz® 481 Low Temperature 70-Durometer Black FFKM O-Rings

Operating temperature: -22°F to +446°F (-30°C to +230°C)

Why Use SIMRIZ® 481 over every other competitor FFKM product:

• Broad chemical resistance in a large number of harsh chemical environments (e.g. strong acids, strong bases)
• Outstanding low temperature performance (-30°C/-22°F)
• Low compression set resulting in an increased product life time
• Without equal. Patented cross-linking system provides superior performance beyond the limits of every other competitor FFKM product
• Demonstrated performance. Successfully used in many customer applications
• Vertically integrated. Freudenberg-NOK Sealing Technologies is the only vertically integrated O-ring manufacturer in the world
• Cost efficient. As the only vertically integrated O-ring manufacturer down to the monomers Freudenberg-NOK Sealing Technologies is able to provide the most cost efficient FFKM O-rings

Typical Applications:

• Pumps
• Valves
• Mechanical Seals
• Dispenser Systems
• Vacuum Components
• Mixers

Designed for thermal stability and nearly universal protection against chemical attack, Freudenberg–NOK’s proprietary family of Simriz® per?uoroelastomer compounds offer premier sealing performance. Simriz® compounds approach PTFE chemical resistance while resisting high temperatures up to 325°C.

Freudenberg-NOK is the only vertically integrated supplier of per?uoroelastomer.
Traceable - Accountable – Customized - Controlled.

Simriz® 481 performs well in a wide variety of harsh chemicals. Its outstanding low temperature performance makes the Simriz® 481 the perfect match for nearly every application in the chemical process industry especially where low temperatures are expected.

SZ481 is a 70-durometer, black, low-compression set, high-strength perfluoroelastomer. The operating temperature range is from -10°C to 230°C (-14°F to 446°F). Typical application environments are aggressive acids, bases and solvents. SZ481 is also suited for many non-oxidizing dry process chemistries. SZ481 can be used in place of Kalrez® compound 6375 when temperature are bellow 230°C.

Designed for thermal stability and nearly universal protection against chemical attack, Freudenberg’s proprietary family of Simriz® perfuoroelastomer compounds offer premier sealing performance. Simriz® compounds approach PTFE chemical resistance and have excellent plasma resistance for dry processing.

Simriz® Perfluoroelastomer compounds provide cost-effective, reliable sealing in a wide range of applications including; automotive, chemical processing, petroleum refining, semiconductor, aerospace, medical, pharmaceutical, food and drug processing, and etc.
