What does FEP stand for?

Fluorinated Ethylene Propylene (FEP) FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP), first produced by DuPont in 1956 (Teflon™ FEP) to reduce PTFE’s high crystallinity and melt viscosity. This improves FEP processing characteristics while maintaining high perfluorination.

What is the difference between PTFE and FEP?

The chemical properties of FEP are similar to those of PTFE and PFA. When FEP is subjected to radiation in air, degradation begins at a dose of 0.2 Mrad (10 times higher than PTFE). FEP polymers are fully fluorinated and melt processible.

What can FEP film be used for?

UV disinfection systems, FEP as release foil for molds in the composite industry. In the chemical industry, because of the unique chemical resistance, as gasket or as separation foil. These are just a few examples. Holscot Europe has set up a special site in order to be able to easily meet the large demand for FEP film: www.FEP-Film.com.

What is the maximum operating temperature of FEP?

It does not have the almost universal chemical resistance of PTFE and PFA and its maximum operating temperature in service is 150°C. This material is often used for the manufacture of “sheet-lined products.” This is essentially a lining made up of sheet and tube elements of FEP welded together in situ.

What is FEP and why is it used?

It is used for applications where the advantages of a Fluoropolymer like PTFE (think Teflon®) is required but the material needs to be meltable and is thus easier to form into different shapes. Holscot in Grantham specialises in the formation of FEP. FEP Film and sheet are similar to other plastic sheets.

What is the formula to calculate FEP?

FEP= (UpxV)/Pp/ Ucr x V) /Pcr = Up x V/Ccr x Pp (3) The Urinary Phosphate to Serum Fibroblast Growth Factor 23 Ratio, Deemed the Nephron Index, Is a Useful Clinical Index for Early Stage Chronic Kidney Disease in Patients with Type 2 Diabetes: An Observational Pilot Study

What is FEP film and sheet?

Holscot in Grantham specialises in the formation of FEP. FEP Film and sheet are similar to other plastic sheets. They come in long rolls and are used for applications where films and sheets are most appropriate.

Who is the founder of the FEP?

Cathy Williams from AFP started the FEPin 2006, no one could have imagined that it would evolve into one of the largest philanthropic research studies in the world. Free measurement tools: growth in giving database offers behavior analysis BANKING AND CREDIT NEWS-February 3, 2016-IFM recognizes FEPCapital with awards

When&how often to replace FEP film?

When & How Often to Replace FEP Film The FEP film is a transparent sheet placed in the bottom of the printing VAT between your UV screen and the build plate, that allows the UV rays to enter and cure the resin. With time, the film may get dirty, scratched, cloudy or worse, punctured and you need to replace it.

What is the difference between PFA and FEP films?

Compared to PFA, FEP films are lower in cost and temperature, and they have a low dielectric constant and dissipation with a continuous use temperature of 400°F (205°C), suitable for use in cryogenic and high temperature applications. CHEMFILM FEP-FG, general purpose film, is manufactured from fluoroinated ethylene propylene resin.
