Vertrel^® XF Select is the ultra-pure version of Vertrel^® XF. It is exactly identical to regular Vertrel^® XF except "Select" is more pure and the manufacturing parameters are more tightly controlled.

In chemical terms, Vertrel^® XF Select is 100% pure HFC 43-10mee which is also known as 2,3-dihydrodeca-fluoropentane. Solvency is mild.

Users select Vertrel^® XF Select because of its unique combination of it is substantially more pure than even ordinary Vertrel^® XF. Specifically, the nonvolatile residues are 50% lower, the moisture is 20% lower, and two other contaminants -- Dioctylphthalates and organic silicones are tightly controlled. These extra parameters ensure that Vertrel^® XF Select can meet the most demanding applications.

Details about the solvent and its physical properties are found in the DuPont Product Spec sheet, available as a PDF file.

Unlike the PFCs, Vertrel^® XF Select is completely miscible with most esters, ketones, ethers, ether-alcohols, and the lower alcohols, such as methanol, ethanol and isopropanol. The lower hydrocarbons, such as hexane and heptane, are also soluble. The cleaner also has excellent materials compatibility. Almost any plastic or elastomer can be safely cleaned in Vertrel^® XF.

Neat Vertrel^® XF Select has limited solvency for many higher molecular weight materials, such as hydrocarbon oils, silicone oils, waxes, and greases; combinations with the many readily-miscible esters, alcohols and lower hydrocarbons can enhance solubility and cleaning efficiency. Vertrel^® XF Select also is an excellent rinsing agent in co-solvent systems.

Like CFC-113 and the PFCs, Vertrel^® XF Select has high solubility for Krytox^® and "Fomblin" fluorocarbon lubricants and can be used either as an application carrier fluid or to remove them.

Data from acute toxicity studies has demonstrated that Vertrel^® XF Select has low toxicity. DuPont has assigned the cleaner an Acceptable Exposure Limit (AEL) of 200 ppm, with a 400 ppm ceiling.

The cleaner is completely nonflammable and does not become flammable during boiling or evaporation. It exhibits no closed or open cup flash point, and is not classified as a flammable liquid by NFPA or DOT. It is thermally stable to 300° C (572° F) and does not oxidize or degrade during storage.

For further details about the safety of the solvent carefully read and understand the data in the DuPont Material Safety Data Sheet, available as a PDF file.

Vertrel^® XF Select has "zero" ozone-depletion potential and low global warming potential. It has been accepted by the U.S. Environmental Protection Agency (EPA) under the Significant New Alternatives Policy (SNAP) program as a substitute for ozone-depleting substances. The component of Vertrel^® XF Select is TSCA listed.

Vertrel^® XF Select is a pure component material, and is easily recoverable by off-line and in-line distillation equipment such as a vapor degreaser or a still. It is thermally stable and does not oxidize or degrade during storage.

Vertrel^® XF Select is commercially available in 55-gal (208-L) drums, 5-gal (20-L) pails, and one-gallon (five liter) packages. Samples in one-liter canisters are available from Micro Care Marketing Services on request. Customers are encouraged to secure samples now for compatibility and performance testing.
