Gap Pad 5000S35
®
High thermal conductivity plus “S-Class” softness and conformability
Features and Benefits
• High thermal conductivity: 5 W/m-K
• Highly conformable,“S-Class” softness
• Natural inherent tack reduces interfacial
thermal resistance
• Conforms to demanding contours and
maintains structural integrity with little or
no stress applied to fragile component leads
• Fiberglass reinforced for puncture, shear
and tear resistance
• Excellent thermal performance at
low pressures

mal resistance. These values are provided for reference only. Actual application performance is directly related to the
surface roughness, flatness and pressure applied.
Gap Pad 5000S35 is a fiberglass-reinforced
filler and polymer featuring a high thermal
conductivity.The material yields extremely soft
characteristics while maintaining elasticity and
conformability.The fiberglass reinforcement
provides easy handling and converting, added
electrical isolation and tear resistance.The
inherent natural tack on both sides assists in
application and allows the product to effec-
tively fill air gaps, enhancing the overall thermal
performance.The top side has reduced tack
for ease of handling. Gap Pad 5000S35 is ideal
for high-performance applications at low
mounting pressures.
Note: Resultant thickness is defined as the final gap thickness of
the application.
