  • Tensile and Elongation properties better than that of standard Homopolymer PTFE

  • Chemical Resistance equal to standard Homopolymer PTFE

Skived Modified PTFE

PRODUCT DESCRIPTION
DW201 is a skived modified homopolymer PTFE (DuPont NXT70)resin containing a higher level of a fully fluorinated comonomer. The incorporation of the comonomer yields a material with improved electrical and physical properties. This film can be thermally bonded (fused) to itself at temperatures of 625° – 650° F.

The modified homopolymer resin exhibits chemical resistance equivalent to that of homopolymer PTFE. Its tensile strength is approximately 25% higher, and the elongation is approximately 60% higher than for homopolymer PTFE. Because of these properties DW201 is often a good substitute for melt processable films such as FEP and PFA.

Note: DW201 can be supplied etched for bonding.

APPLICATION INFORMATION
DW201 may be thermally fused to itself making possible the fabrication of structures used in medical applications, as well as other products fabricated by thermally welding of films together.

DW201 can also be used as a high dielectric strength fusible wrap in electrical and electronic cable applications as well as being used as a bonding film in the circuit board industry.
