GAP PAD TGP 5000

## **Ga Pad® 5000S35 p** 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 

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 effectively 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.

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] . For more information on Gap Pad modulus, refer to Bergquist Application Note #116. 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.
