GAP PAD 0.125" SHEET 100MMX100MM

## **Gap Pad® VO** 

July 2011 

## **PRODUCT DESCRIPTION** 

Conformable,Thermally Conductive Material for Filling Air Gaps 

## **FEATURES AND BENEFITS** 

- Thermal conductivity: 0.8 W/m-K 

- Enhanced puncture, shear and tear resistance 

- Conformable gap filling material 

- Electrically isolating 

Gap Pad[®] VO is a cost-effective, thermally conductive interface material.The material is a filled, thermally conductive polymer supplied on a rubber-coated fiberglass carrier allowing for easy material handling.The conformable nature of Gap Pad[®] VO allows the pad to fill in air gaps between PC boards and heat sinks or a metal chassis.
