What is Chemraz 505?
Greene Tweed’s Chemraz® 505, a perfluoroelastomer, provides a broad range of chemical resistance, and is available for use as o-rings, gaskets, and many other custom shapes.
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.
What is Chemraz o ring?
Chemraz® O-Rings Chemrz® o-rings offer the ultimate resistance to high temperatures, chemicals and solvents due totheir FFKM base materials. They’re the ideal material for demanding applications in the semiconductor, energy and life science industries.
What is FFKM o ring material?
FFKM is a family of perfluoroelastomer compounds that contain even higher amounts of fluoride than FKM. FFKM o-rings provide exceptional high temperature and chemical resistance, and can even withstand prolonged exposure to oxygen-plasma.
What is the difference between Chemraz and kalrez?
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.
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 the difference between Kalrez and Chemraz?
Is Kalrez the same as Chemraz?
What is the difference between Chemraz and Kalrez?
Is FFKM FDA approved?
Developed for food and pharmaceutical processing, automated CIP and SIP systems and is FDA compliant to 21 CFR 177.2600.
Is Kalrez the same as Viton?
The name Kalrez® is a trademark of Dupont. The material is actually an improved version of Viton with 20% more fluorine in the chains, making it an extremely expensive per fluorocarbon elastomer.
Is FFKM a Teflon?
Teflon (PTFE) and Kalrez (FFKM) are different polymers. PTFE is made from tetrafluoroethylene, and contains only carbon and fluor. The material is stiff. FFKM is made from tetrafluoroethylene, vinylidene fluoride and perfluoromethylvinylether, so besides carbon and fluor, it also contains hydrogen and oxygen.
Is FKM FDA approved?
Known more commonly by its trade name of Viton™, fluorocarbons or FKM are high performance FDA approved silicone materials. They cope well with high temperatures, are chemically resistance and do not absorb water.
Is Kalrez 6375 FDA approved?
FFKM – 80 Shore A – Kalrez 6375 The temperature that these FFKM O-rings can handle is from -20 °C to +270 °C. These O-rings are FDA approved. The hardness of this O-ring is 80 Shore.
What is the difference between FKM and FFKM?
The key difference between FKM and FFKM is that FKM offers a less degree of versatility compared to that of FFKM. FFKM can withstand comparatively high temperatures than FKM. Moreover, FKM is more resistant to burning than non-fluorinated hydrocarbon compounds while FFKM is self-extinguishing and non-flammable in air.
Is Viton an FKM or FFKM?
Both materials are well suited for use in the -15 to 205°C range. FKM has an advantage in lower temperatures and FFKM has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.
