Is Kalrez the same as Chemraz?

Is Kalrez the same as Chemraz?

Chemraz® (FFKM)– (Green Tweed’s trademark name) Chemraz® is the Green Tweed version of Kalrez® (a Dupont trademark), Simriz® (a Simrit trademark), Markez® (a Marco Rubber trademark) or FFKM.

What is Chemraz 505?

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. Chemraz 584 and 585 are the elastomers of choice for strong oxidatio and hot aqueous fluids.

Is fluorocarbon the same as Viton?

Viton® is the brand name for fluorocarbon rubber polymers of the Chemours Company. This type of polymer is used extensively by ERIKS, however we do not claim or promote the use of any specific brands of polymers in our compounds.

What material is Viton?

Viton™ is a fluoropolymer elastomer and synthetic rubber compound, trademarked by DuPont under this brand name. It’s a fluorinated hydrocarbon rubber product with amazing capabilities, designed to withstand even the most challenging of environments.

How is FFKM made?

FFKM is made up of 72.5% fluorine with a fully fluorinated backbone chain, which is the absolute maximum level of fluorination possible whilst still retaining the elastomeric properties needed for the development of high performance ‘O’ rings.

Is Viton FKM?

Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same. FKM is the American standard ASTM short form name for Fluro-Elastomer.

What’s the difference between chemraz and Kalrez in temperature?

The effective temperature range for Kalrez is +5ºF to + 600ºF, for Chemraz –20ºF to +450ºF. A white Chemraz compound is available and features less impurities and less electrical conductivity.

What’s the difference between chemraz FkM and FFKM?

Chemraz® FFKM Overview FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C (617°F). FFKM also has improved chemical resistance, with nearly universal chemical compatibility.

What kind of chemical resistance does chemraz have?

Chemraz ® is a polymer of three or more monomers in which all hydrogen positions have been replaced with fluorine. It has the broadest chemical resistance of any elastomeric material.

Which is the best Markez compound for FFKM?

Markez ® compound number Z1028 is our most popular general purpose FFKM compound due to its relative low cost and broad range of chemical and temperature resistance up to 610 ºF (320ºC). Popular sizes are available in stock with rush manufacturing options available.
