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 -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.

Simriz® Compound: SZ484

SZ484 is a FDA compliant, 75-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 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 -10°C to 230°C (-14°F to 446°F). 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 230°C.

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 -10°C to 300°C (-14°F to 572°F). 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 -10°C to 300°C (-14°F to 572°F). Typical application environments for SZ488 seals are aggressive dry process chemistries, including reactive plasmas.

Simriz® Compound: SZ489
