Pyralux® TA/TAS, TAH/TAHS - low loss polyimide solutions

DuPont™ Pyralux® TA series are all polyimide copper clad laminates designed for high speed high frequency applications. They offer ideal balance between low loss performance, good bendability and easy processability. 


  • Low dissipation factors (Df) enables low dielectric loss
  • Excellent static bending repeatability and mechanical performance
  • Same process as processing standard PI based FCCL
  • Pyralux® TA can pass 350oC solder floating test (10sec * 3 times), and is compatible with hot bar process


  • TA122512 & TA125012: Double sided clad with electro deposited copper
  • TAS122500 & TAS124500: Single sided clad with electro deposited copper
  • TAH125012B: Double sided clad with rolled annealed copper
  • TAHS124500B: Single sided clad with rolled annealed copper
