Test Data Comparing Kalrez 6375, Simriz SZ485, and Simriz SZ487

Simriz Compound: SZ481
SZ481 is a 70-durometer, black, low-compression set, high-strength perfluoroelastomer.  The operating temperature range is from -10C to 230C (-14F to 446F).  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 230C.

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

Simriz Compound: SZ485       (Standard material for best $ and availability)
SZ485 is a 75-durometer, black, low-compression set, high-strength perfluoroelastomer.  The operating temperature range is from -10C to 230C (-14F to 446F).  Typical application environments are aggressive acids, bases, solvents, and steam.  SZ485 is also suited for many non-oxidizing dry process chemistries.   SZ485 can be used in place of Kalrez compound 6375 when temperature are bellow 230C.

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 SZ486 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 -10C to 300C (-14F to 572F).  Typical application environments are aggressive acids, bases and solvents.  SZ487 can be used in place of Kalrez compound 4079.  Used in dry, high heat below 300C.

Simriz Compound: SZ488
SZ488 is a 70-durometer, ivory, high temperature perfluoroelastomer.  The operating temperature range is from -10C to 300C (-14F to 572F).  Typical application environments for SZ488 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 forSZ489 seals are aggressive dry process chemistries, including reactive plasmas, as well as aggressive acids, bases and solvents.
