Are KEL-F® and PCTFE the same?
What is Kel-F? Kel-F® was a trade name for PCTFE (polychlorotrifluoroethylene) utilized by the 3M® Company. In 1995, 3M sold the rights to Daikin® Industries, Ltd, who produces the raw material today under the trade name Neoflon®. PCTFE with the brand Kel-F is no longer available in the marketplace.
What is Neoflon PCTFE M-400H?
Neoflon PCTFE M-400H is a fluoropolymer that has high tensile strength, dimensional stability, and retains its high-performance properties over a large temperature range (-400° to 380°F). This grade of PCTFE has superior mechanical characteristics and gas barrier properties to PFA and FEP. PCTFE is melt-processible, and can be extruded or molded into sheets, rods or tubes.
What are the Benefits & Advantages of PCTFE?

Low gas permeation and outgassing
Very low moisture absorption and permeation
Highly resistant to cold flow
Very rigid and tough
Excellent dimensional stability
Extremely good low temperature properties to -400°F
Resistant to oxidation
High compressive strength
What Types of Products can be Manufactured from PCTFE?
