What is Kalrez not compatible with?
KALREZ perfluoroelastomer parts, like all fluorinated prod- ucts, should not be exposed to molten or gaseous alkali metals, such as sodium and potassium, because a highly exothermic reaction may occur.
What is chemical compatibility matrix?
This Chemical Compatibility Chart is a shorthand tool for describing the suitability of miniature fluidic and pneumatic component materials for use in contact with various chemicals.
Is Kalrez the same as FFKM?
Perfluoroelastomers (FFKM) are best known as DuPontTM Kalrez, although other grades do exist. The compounds contain fully fluorinated polymer chains and hence offer the ultimate performance of elastomers when considering heat and chemical resistance.
Is EPDM chemical resistant?
While EPDM is compatible with a wide range of chemicals, it offers no resistance to hydrocarbon fluids. Additionally, EPDM seals absorb oil and gas, making them a weak defense in oil and gas applications.
What is chemical compatibility test?
This test covers the evaluation of plastic materials for resistance to chemical reagents, simulating performance in potential end use environments. Chemical reagents can include lubricants, cleaning agents, inks, foods, or anything else that the test material may be expected to come in contact with.
What are the five Compatibility groups for chemicals in stores?
Chemical compatibility groups
- Flammable liquids.
- Compressed gases.
- Volatile poisons.
- Acids.
- Liquid bases.
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 kind of material is kalrez?
It is a carbon black filled product with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic acids, inorganic acids and aldehydes, and has good response to temperature cycling effects.
