- 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. 

Gap Pad 2000S40 is recommended for lowstress applications that require a mid to high thermally conductive interface material.The highly conformable nature of the material allows the pad to fill in air voids and air gaps between PC boards and heat sinks or metal chassis with stepped topography, rough surfaces and high stack-up tolerances. 

Gap Pad 2000S40 is offered with inherent natural tack on both sides of the material allowing for stick-in-place characteristics during application assembly.The material is supplied with protective liners on both sides.The top side has reduced tack for ease of handling.
