Characteristics and Advantages

  • High vibration reduction, shock absorption
  • No melting point and heat resistance (Reflow soldering resistance)
  • Good adhesion to metal plates
  • Flexibility and rubber elasticity
  • Good insulation

Shock absorption property

Good compared to existing forming films and gel films

Vibration damping property

The epoxy film has a good vibration damping property compared to a existing film.
Measurement of vibration damping on aluminum plate
*Inertance is the value that vibrational acceleration is divided by stress given by a hammer.

Applicable components

  • Vibration damping and shock absorption for automobile parts
  • Shock absorption property to CFRP

Proposal for the future

  • Reduction of the sound in EV car
  • Adhesive sheet to fill up in narrow gap between electronic parts
