Laird Tflex 700 Series Thermal Gap Filler Pad Performance Materials
Please check back at a later stage.
Product Description
Laird Tflex 700 is a 5 W/mK soft gap filler thermal interface material with great thermal performance and high compliancy. The soft interface pad conforms to component topography, resulting in little or no stress on the components and mating chassis or parts.
Unique silicone and ceramic filler technology allows a combination of high compliancy and high thermal performance. Tflex 700 is stable from -45ºC thru 200ºC and meets UL 94V0 flame rating. Naturally tacky, it requires no additional adhesive coating which inhibits thermal performance.
STANDARD THICKNESSES Standard thickness 0.020" (0.5mm) through 0.200" (5.0mm) available in 0.010" (0.25mm) increments. MATERIAL NAME AND THICKNESS Tflex - indicates elastomeric gap filler product line. 7XXX - indicates Tflex 700 product line and thickness in mils (0.001-inches). -DC1 - one side tacky; default is both sides tacky. Data for design engineer guidance only. Observed performance varies in application. Engineers are reminded to test the material in application.

You guys are the best in the business! I will always buy your products as long as you keep up the quality and love of the craft I've seen so far! On the actual delivery, FedEx delivery in Northern Sweden is an absolute farse. They use two sub-contractors and the ones actually delivering the package literally looked me in the eye as he drove by before I got a notification that they couldn't deliver that day. When I called the first sub-contractor to FedEx to put pressure on the delivery guy, he arrived a few minutes later and said he didn't even have my package in the car when he drove past (and reported he couldn't deliver because "I was unreachable"). FedEx use Lastbilsstation.se as their main subcontractor, who in turn use JetPak. JetPak is absolutely horrid. My suggestion for delivery in the Scandinavian countries would be PostNord, they suck, but not as bad. Regardless, I will still buy products from ModDIY as there simply isn't a company with better products, customer service (shoutout to Carrie, absolute legend!), and love of the craft. Next time though, I'll ensure that what I order is less urgent so the FedEx shenanigans won't affect me as much. 10/5 stars for ModDIY 0,5/5 stars for the delivery

I am really pleased.... The items were very well packaged in a strong padded envelope that is recyclable. The shipping options are great and prices were really competitive, especially with the coupon code that I found online. I feel confident to purchase here again for a larger order. I am however not a fan of the molex removal tool, as the steel is not spring steel. It did not resist to the tough job I had for it. I am hoping customer service will be able to help me out.
