Gap Pad

Gap Pad VO Ultra Soft

Features & Benefits

  • Thermal conductivity: 1.0 W/m-K
  • Highly conformable, low hardness
  • "Gel-like" modulus
  • Decreased strain
  • Puncture, shear and tear resistant
  • Electrically isolating

Description

Gap Pad VO Ultra Soft is recommended for applications that require a minimum amount of pressure on components. The viscoelastic nature of the material also gives excellent low stress vibration dampening and shock absorbing characteristics. Gap Pad VO Ultra Soft is an electrically isolating material, which allows its use in applications requiring isolation between heat sinks and high-voltage, bare-leaded devices.

Typical Applications include

  • Telecommunications
  • Computer and peripherals
  • Power conversion
  • Between heat-generating semiconductors or magnet components and a heat sink
  • Area where heat needs to be transferred to a frame, chassis, or other type of heat spreader

  • (1) Thirty second delay value Shore 00 hardness scale.

  • (2) Young's Modulus, calculated using 0.01 in/min. step rate of strain with a sample size of 0.79 inch^2.

  • (3) The ASTM D5470 test fixture was used. The recorded value includes interfacial thermal resistance. These values are provided for reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied.
