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 -10ºC to 230ºC (-14ºF to 446ºF). 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 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 material for best $ and availability)
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. 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 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 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 -10ºC to 300ºC (-14ºF to 572ºF). 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 -10ºC to 300ºC (-14ºF to 572ºF). 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.
