Gap Pad 1500S30
®
Highly Conformable,Thermally Conductive, Reinforced “S-Class” Gap Filling Material
Features and Benefits
TYPICAL PROPERTIES OF GAP PAD 1500S30
• Thermal conductivity: 1.3 W/m-K
• Highly conformable / low hardness
• Decreased strain on fragile components
• Fiberglass reinforced for puncture, shear
and tear resistance
• Quick rebound to original shape
Gap Pad 1500S30 is a highly compliant
Gap Pad material that is ideal for fragile
component leads.The material is fiberglass
reinforced for improved puncture resistance
and handling characteristics. Gap Pad
1500S30 maintains a conformable, yet elastic
nature that provides excellent interfacing and
wet-out characteristics, even to surfaces with
high roughness or uneven topography.
Gap Pad 1500S30 features an inherent tack
on both sides of the material, eliminating the
need for thermally impeding adhesive layers.
Note: Resultant thickness is defined as the final gap
thickness of the application.
