505 75 Black -20 to 425 1750 450 1150 140 25
A field proven universal compound having a broader range of chemical resistance than any other single compound on the market. Chemraz 505 is the elastomer of choice used to seal better than 90% of the most demanding services found in the chemical process and refining industries.
615 80 Black 0 to 615 1830 360 1090 135 16
The highest temperature perfluoroelastomer on the market. Chemraz 615 can handle continuous operating temperatures up to 615ºF with outstanding resistance to fatal thermal related compression set.

605

80 Black 0 to 500 2150 420 1310 130 20
A high temperature compound with superior physical properties and chemical resistance comparable to Chemraz 505. This compound excels in demanding dynamic applications and exhibits unparalleled performance in high temperature steam and water.  Chemraz 605: Recently received USP Class VI Certification

526

95 Black 0 to 500 2580     100 30
This specialty black compound was formulated for incredible resistance to explosive decompression damage common in high pressure gas services. Chemraz 526 is also used in monomer services where polymerization attacks and ruptures common elastomeric seals.
