Ultra-Thin 60D TPU Coating on PI Substrate

Precision Ultrasonic Spraying for Ultra-Thin 60D TPU Coating on PI Substrate

Ultrasonic spraying is a high-precision, non-contact coating solution ideal for applying ultra-thin, uniform thermoplastic polyurethane (TPU) layers on polyimide (PI) substrates. This advanced atomization coating process delivers consistent film thickness, minimal material waste, and zero mechanical damage to delicate PI base materials, making it suitable for precision industrial tubular component manufacturing.

  • Finished inner diameter: 0.020 inch (0.5080 mm)
  • PI inner tube outer diameter: 0.02335 inch (0.5931 mm)
  • Minimum TPU coating wall thickness: 0.0002 inch (0.00508 mm)
  • Standard tube length: 48 inch (1219.2 mm)

Process & Material Advantages

The combination of high-stability PI substrate and ultra-thin 60D TPU coating brings excellent comprehensive performance. PI material features outstanding high-temperature resistance, insulation and dimensional stability, while the precision-sprayed TPU layer provides enhanced surface toughness, wear resistance and protective performance. The ultrasonic spraying technology realizes controllable ultra-thin coating with uniform thickness, no uneven coating or material accumulation, ensuring high consistency of batch-produced tubular components.

Application Scenarios

This precision ultrasonic spraying coating process is widely applicable to high-precision tubular parts in electronics, precision machinery, industrial insulation and other fields, meeting the strict dimensional tolerance and surface protection requirements of high-end industrial components.
