Simriz® Compound: SZ481
SZ481 is a 70-durometer, black, low-compression set, high-strength perfluoroelastomer.   The operating temperature range is from -10ºC to 230ºC (-14ºF to 446ºF).   Typical application environments are aggressive acids, bases and solvents.   Z1001 is also suited for many non-oxidizing dry process chemistries.    Z1001 can be used in place of Kalrez® compound 6375 when temperature are below 230ºC.

Simriz® Compound: SZ484
SZ484  is a FDA compliant, 75-durometer, black, low-compression set, high-strength perfluoroelastomer.  The operating temperature range is from -10ºC to 230ºC (-14ºF to 446ºF).  Typical application environments are aggressive acids and bases.

Simriz® Compound: SZ485* (Standard compound, most readily available and cost effective)
SZ485 is a 75-durometer, black, low-compression set, high-strength perfluoroelastomer.   The operating temperature range is from -10ºC to 230ºC (-14ºF to 446ºF).   Typical application environments are aggressive acids, bases, solvents, and steam.   Z1005 is also suited for many non-oxidizing dry process chemistries.    Z1005 can be used in place of Kalrez® compound 6375 when temperature are below 230ºC.

Simriz® Compound: SZ486
SZ486 is A 80 -durometer, white low-compression set, high strength perfluoroelastomer.   The operating temperature range is from -10C to 230C (-14F to 446F).  Typical application environments for Z1006 seals are aggressive dry process chemistries, including reactive plasmas.

Simriz®  Compound: SZ487
SZ487 is a 75-durometer, black, high temperature perfluoroelastomer.  The operating temperature range is from -10ºC to 310ºC (-14ºF to 615ºF).  Typical application environments are aggressive acids, bases and solvents.  Z1007 can be used in place of Kalrez® compound 4079.  Used in dry, high heat below 310C.

Simriz® Compound: SZ488
SZ488 is a 70-durometer, ivory, high temperature perfluoroelastomer.  The operating temperature range is from -10ºC to 300ºC (-14ºF to 572ºF).  Typical application environments for Z1008 seals are aggressive dry process chemistries, including reactive plasmas.

Simriz® Compound: SZ489
SZ489 is a 65-durometer, clear, clean perfluoroelastomer.  The operating temperature range  is from -10C to 260C (-14F to 500F).  Typical application environments for Z1009 seals are aggressive dry process chemistries, including reactive plasmas, as well as aggressive acids, bases and solvents.

Description: Excellent resistance to almost all chemicals. Excellent outgassing performance in vacuum environments.

Limitations: Avoid low-molecular-weight, fully halogenated fluids and molten alkali metals.
Especially strong oxidizing acids may cause some swelling.  Helium permeability is slightly higher than fluoroelastomer compounds. Specific Simriz® compounds provide better low-temperature performance and amine resistance.

Chemistry: Copolymer of tetrafluoroethylene and perfluorovinyl ether.
