Perfluoroelastomer

Get Instant Quality Info at iZito Now! Il perfluoroelastomer o (FFKM) è l’elastomero più resistente agli agenti chimici disponibile ed è effettivamente una forma di gomma di PTFE. PERFLUOROELASTOMER (FFKM) MATERIAL The name “perfluoroelastomer” is somewhat misleading.

An actual perfluorinated material with a high molecular weight is polytetrafluoroethylene or PTFE which has the chemical formula (CF2)n. The molecular carbon chain is shielded by the chemical inertness of the large bonded fluorine atoms.

They have improved resistance to high temperatures and chemicals and even withstand environments where Oxygen-Plasma are present for many hours.

Global O-Ring and Seal provides high-performance FFKM o-rings for your demanding applications. Certain grades have a maximum continuous service temperature of 3°C (6°F). CV ALD and LPCVD. Perfluoroelastomer s contain an even higher amount of fluorine than FKM.

It offers outstanding thermal stability, very low outgassing and excellent (low) compression set properties. Besides it doesn’t settle on key mechanical properties, for example, pressure set opposition, volume swell obstruction and tractable properties. 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.

Gli o-ring del perfluoroelastomer o (FFKM) sono raccomandati per il loro ampio intervallo di temperature, resistenza chimica in numerose applicazioni aggressive e lunga durata. All FKMs contain vinylidene fluoride as a monomer. Fluoroelastomers are more expensive than neoprene or nitrile rubber elastomers. Poor: Abrasion Resist.

Insights pertaining to revenue generate production capacity and estimated growth rate of all the regions listed is enlisted. Its fully fluorinated backbone structure provides a very broad chemical and thermal stability. Delivered Product Form Dyneon PFE is packaged in crumb form. So, fluorinated elastomers containeither a partially or fully fluorinated backbone.

The polymer backbone comprises many repeating monomerunits. Typical monomer units for these polymers are shown below. It has the highest density and the lowest ductility among rubber materials.

Our manufacturing plant as well as our know-how enable us to mould all vulcanized elastomers and thermoplastics on the market. The choice of the most suitable material is essential to get a high-quality product. FFKM shows low swell in organic and inorganic acids and aldehydes.

It resists nearly all chemical attack and provides long-term service in corrosive environments. Unlike silicone tubing, Series PFL is manufactured with a patented composite of platinum-cured perfluoroelastomer and expanded polytetrafluoroethylene (ePTFE) for increased reliability with aggressive chemicals in peristaltic pumps.

Ningbo Kaxite Sealing Materials Co.

Kaxite is one of the biggest sealing and heat preservation products manufacturer in China. FFKM is used when FKM finds its limitations. FFKM has better resistance to high temperatures, for an almost universal chemical compatibility (excpet with fluorinated products such as freons). Properties such as high-temperature stability, universal chemical resistance and superior mechanical properties, to name a few, largely contribute to the increased adoption of perfluoroelastomer products in.

FFKM o-rings are specifically manufactured for extreme applications where up time performance is worth the significantly higher cost compared to other basic materials. Please obtain more information on spare parts, servicing, maintenance, Repair, repair or accessories directly from the registered companies. This paper is a review of perfluoroelastomer s and fluoroelastomers used in semiconductor wafer processing.

Sometimes considered the rubber version of PTFE, a perfluoroelastomer contains a fully fluorinated polymer backbone and a proprietary cure system. Today, mechanical seals are becoming smaller and lighter, yet are required to perform just as efficiently as larger mechanical seals.

Their long-term resistance to the harshest chemicals and the highest temperatures makes them resistant to swelling and embrittlement, a leading cause of premature seal failure.
