Is FEP the same as PTFE?

Is FEP the same as PTFE?

PTFE and FEP are similar in their material properties. The main difference between PTFE and FEP lies in the maximum operating temperature and the colour. PTFE is milky/white and FEP is clear transparent.

What is Fluoroplastics?

Fluoroplastics is a clumsy word given to a group of plastics where the molecules consist of a carbon chain with fluorine atoms attached. These fluorine atoms dramatically change the properties of the material, and give fluoropolymers special properties. Non-stick characteristics and low friction surface.

What is FEP material?

FEP (fluorinated ethylene propylene) is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required.

Is PTFE safe?

How Safe is PTFE? Unlike PFOA and PTFO, PTFE is not considered to be a health risk, but there’s still a lot of attention over its safety. After much research, it’s been determined that PTFE isn’t toxic and that’s it’s safe for human consumption.

What type of polymer is PTFE?

PTFE is a linear polymer of tetrafluoroethylene (TFE). It is manufactured by free-radical polymerization mechanism in an aqueous media via addition polymerization of TFE in a batch process.

What is polytetrafluoroethylene used for?

Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals.

What is the material PTFE?

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties.

Is PTFE a resin?

Teflon™ PTFE (Polytetrafluoroethylene) / Resin Information & Properties. Teflon™ NXT 85 Modified PTFE is a chemically modified resin that offers improved resistance to deformation under load, increased resistance to permeation of chemicals, and higher dielectric breakdown strength in comparison with virgin PTFE.

Why are PTFE, FEP and PFA used as fluoroplastics?

PTFE, FEP and PFA are extremely lubricious and therefore offer excellent non-stick properties. However, this is a problem should you wish to bond these materials to a substrate. By chemically etching the PTFE or any of the other fluoropolymers we offer you strip away the fluorine atoms, which then provides a suitable surface for bonding.

Which is better for moulding PTFE or FEP?

FEP has very similar properties to PTFE, but has a lower maximum operating temperature of +200°C. However, FEP can be more easily processed and can be easily welded and re-moulded into complex profiles. As well as possessing the unique properties of fluoroplastics, FEP enjoys these benefits: Welding and re-moulding potential

Which is melt processible PTFE or Neoflon FEP?

NEOFLON FEP (Fluorinated Ethylene Propylene copolymer) is a melt processible fluoropolymer. Although it is lower melting than PTFE, it still maintains a continuous service temperature of 200°C.

What is the difference between PFA and FEP?

The benefits of PFA PFA, or Perfluoralkoxy, is a high temperature version of FEP. PFA has similar properties to FEP but can be used at working temperatures up to +260°C while remaining melt-processable, thanks to a lower melt viscosity than PTFE.
