Pyralux® TK

Pyralux® TK Kapton® & fluoropolymer double-sided copper-clad laminate


Pyralux® TK Kapton® & fluoropolymer double-sided copper-clad laminate features a proprietary layered dielectric, comprising both Kapton® polyimide film and fluoropolymer films. This unique composition affords the lowest loss performance for a Pyralux® copper-clad laminate, enabling remarkable signal integrity in high-speed digital and high frequency circuit applications. Offered with both rolled annealed (RA) and electrodeposited (ED) copper foil, Pyralux® TK can address your highest performance flex and rigid-flex applications where dielectric constant must fall below 3.0.

Features & Benefits

  • Fluoropolymer films provide low loss dielectric constant loss tangent
  • Low moisture absorption for consistent performance
  • Balanced and unbalanced constructions available

Applications

  • High speed and high-frequency flexible circuit constructions
  • High performance rigid flex circuit constructions
  • Multilayer flexible circuits requiring very low dielectric constant
  • Signal integrity critical flexible and rigid flex designs
