Features and Benefits

• Thermal conductivity: 1.0 W/m-K

• Highly conformable, low hardness

• “Gel-like” modulus

• Decreased strain

• Puncture, shear and tear resistant

• Electrically isolating

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.

Note: Resultant thickness is defined as the final gap

thickness of the application.

Typical Applications Include:

• Telecommunications

• Computer and peripherals

• Power conversion

• Between heat-generating semiconductors or magnetic components and a heat sink

• Area where heat needs to be transferred to a frame, chassis, or other type of heat spreader

Configurations Available:

• Sheet form and die-cut parts
