产品说明
DW 201 is skived from a modified homopolymer PTFE (Dupont NXT70)resin containing a higher level of a fully fluorinated comonomer. The incorporation of the comonomer yields a materail with improved electrical and physical properties. This film can be thermally bonded (fused) to itself (625 - 650 degrees F). The modified homopolymer resin exhbits 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 DW 201 is often a good substitute for melt processable films such as PFA. Product can be supplied etched for bonding.
DW 201 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. DW 201 can also be used as a high dieclectric strength fusible wrap in electrical and electronic cable applications. It can be used as a bonding film in the ciruit board industry.
