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.
What is Viton not compatible with?
It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones. Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc.
What is Chemraz?
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.
Are Viton seals good for bleach?
Determine Chemical Compatibility If you use sodium carbonate — a commonly used disinfection compound — it is compatible with both types of O-rings, so we’d recommend using Buna. Sodium Hypochlorite (household bleach), on the other hand, can degrade Buna seals, making Viton the better choice.
What is Kalrez material?
Kalrez® 1050LF is a carbon black-filled product for O-rings, seals, and other parts used in chemical process industries. It has good hot water/steam, and excellent amine resistance. Designed for low-temperature environments where significant chemical resistance is required.
Who makes Viton?
Viton™ is a fluoropolymer elastomer and synthetic rubber compound, trademarked by DuPont under this brand name.
Is Viton compatible with Skydrol?
What Seals are compatible with Skydrol? Elastomers are the big issue. Don’t get it wrong. Nitrile, Buna-N, silicone, fluorosilicone and Viton fluorocarbon are totally unsuitable.
Is Viton compatible with caustic soda?
Unlike EPDM, Viton has a good resistance to oils, fuels, lubricants, and most mineral acids. It is resistant to most chemicals, but not to for example Acetic acid, Ammonia, Caustic soda, Formic acid and Potassium hydroxide.
What is kalrez made of?
Because Kalrez® parts maintain their sealing integrity, you reduce your risk of environmental non-conformance. Kalrez® parts are made only by DuPont, a fully integrated manufacturer of Vespel® parts and shapes, Viton® fluoro elastomers and Neoprene rubber polymers, as well as perfluoroelastomer parts.
What is FFKM O ring material?
FFKM o-rings are the highest high-performance family of o-rings with the highest temperature (up to 620F) and ultimate chemical resistance. FFKM o-rings are specifically manufactured for extreme applications where up time performance is worth the significantly higher cost compared to other basic materials.
What is the use of O ring?
The function of O rings is to seal a joining of two pieces to ensure that no air, gas or liquid can pass. Typically, they are fitted into a groove and designed to resist pressure. The resistance is what prevents air or liquid from escaping or entering the joining.
Which is the best O ring for chemraz?
Chemraz ® o-rings from Marco Rubber are available in Greene Tweed perfluoroelastomer compounds as high temperature o-rings and chemically resistant o-rings to meet extreme application conditions. Contact a perfluoroelastomer oring sealing expert today for help selecting the best Chemraz ® o-ring compound for your application.
Which is the best chemraz 605 high temperature O ring?
Chemraz 605 features even wider range of chemical resistance and also medical grade USP Class VI Certified. Chemraz 615 high temperature perflouroelastomer o-ring material can perform up to 620 ºF (325ºC).
Which is the best elastomer for chemraz 584?
Chemraz 584 and 585 are the elastomers of choice for strong oxidation fluids and hot aqueous solutions. This specialty cream Chermaz compounds are formulated to withstand the most demanding chemical process applications.
Which is the best O ring material for chemical processing?
Chemraz 505, for instance, is the o-ring material of choice for demanding services in basic chemical processing. Chemraz 605 features even wider range of chemical resistance and also medical grade USP Class VI Certified.
