Keratherm Softtherm®: 86/225

This new single-layer fiberglass-reinforced Softtherm® film is produced in thicknesses from 0.5mm to 5.0mm and has good self-adhesive behavior on both sides. Good thermal values and very good dielectric properties characterize this film.

The film’s ideal Shore hardness guarantees very good compressibility and good relaxation, along with vibration damping characteristics.

Possible Thickness: 0.5mm - 5.0mm

Applications

  • Heat Pipe Thermal Solutions
  • Automotive Engine
  • Control Systems
  • Control Units
