Thermal Insulators | Laird/DuPont | TGard | High Conductivity
At NEDC, we sell a lot of thermal pads. We also sell a lot of die-cut thermal insulators. When I hear of a die-cut thermal insulator, I usually think of a thermal pad that is on the thinner side that has added pressure to achieve its thermal properties. As discussed...
Tackiness on Thermal Pads, Gap Fillers | With, or Without?
It is no secret that NEDC has a thermal pad test machine at its facility in Methuen, MA. We test a lot of thermal pads. We stack them, sort them by apparent thermal conductivity, by bulk thermal conductivity, test with liners, without liners, with PSA, without PSA… In...
CoolZorb™ Thermal/EMI Absorbers | Custom Die Cutting/Waterjet Cutting
At NEDC, we have a core competency of thermal pads, and RF absorbers. We were wondering the other day, what if there was a product that did both conducting heat out of an application, while also absorbing RF waves, and giving it off as heat. Well, that would be an...
NEDC Releases New Graphic Showing Product Groupings!
This blog post is all about the image we releasing. In this image, NEDC is showing a die-cut insulator, a thermal pad, an RF absorber, some die-cut gaskets, and an epoxy film that are all present on a typical application that we might service
Video on Thermal Pad Comparisons, Thermal Conductivity is Not Everything!
In this episode, NEDC (the Network for Engineering and Device Cooling) conducts a detailed examination of two different types of thermal pads, focusing on how their thermal conductivity affects their performance in real-world applications. The primary distinction...

Frozen Epoxy Films in Stock at NEDC!
NEDC is a converter of frozen epoxy films to make custom preforms for customers to buy. For that reason, NEDC has many frozen films in stock. These include: Ablefilm 5025E Ablefilm 561K Ablefilm CF3350 Ablefilm 566K And others. We wanted to just get it out there on...
HPMS Graphite | Flexible Graphite | Custom Die-Cut Parts
At NEDC, we like to think we are experts in thermal interface materials. Flexible graphite material is an excellent thermally conductive material. In fact, I see a lot of thermal interface pads going in this direction due to its great thermal conductivity, & low...
EMI/RFI Bulb/Hollow Gaskets – The Softest EMI/RFI Gasket
At NEDC, we mostly die-cut, knife-cut, or waterjet cut gaskets. However, we do also fabricate, glue, or bond together some gaskets. Why do we do this? The short answer is because we cannot die cut, or waterjet cut them. However, sometimes it's also for performance...
Nickel Coated Aluminum Gaskets | EMI Gaskets | Corrosion Resistant Gaskets
EMI/RFI Gaskets are not a new technology. They have been around for the last 60 years. However, once in a while a new technology emerges for a different type of foam, or a different type of orientation of materials. Over the last few years, a new type of particle has...
Long Shelf Life Electrically Conductive Single/Double | EMI Shielding Tapes
We are a 3M converter, and if I’m being honest, I don’t throw a party everytime they come out with a new product. I like new copper foil products, and new VHB Tapes just like the next guy, but nothing gets me going like: “LONGER SHELF LIFE ELECTRICALLY CONDUCTIVE...
Thermal Interface Pads/Liquids for Solid State Drives(SSDs)
As the industry moves from hard-drives(HDDs) to solid-state drives(SSDs). SSDs offer significant advantages over their hard drive counterparts. However, since SSDs operate through an electrical current, they still get hot- just like every electronic. Heat continues to...
Engineering Note: Hole Diameters: How low can you go?
At NEDC, cutting gaskets is what we do. Gaskets typically have holes in them to provide room for screws or bolts to go through them in order to provide pressure, and then for that reason, also to provide compression for the gasket to seat/seal properly. How small is...
