R10400M (Medium) Flame Retardant Silicone Sponge | Custom Die-Cut Parts
Silicone Sponge, and Silicone Foam are different. I’ve talked about that in another blog on our website. Both have desirable properties. Some have good physical properties, and some have good flame retardant properties. There are some products that can actually be...
Thermal Pad vs. Thermal Grease/Mica
One common question I hear engineers ask about is if it's better to have Mica/Grease or Sil-Pad products. Obviously, I’m partial to this, but I wanted to give some thoughts I had about Mica/Grease, and why I think it has its place, but why I think in a manufacturing...

Over the past two years, silicone foam has become a particularly challenged material when it comes to lead times. As of this writing, there has been cases where we have waited a year for some silicone foam. Although, it is true, lead times have improved dramatically...
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...
Liners for Die-Cutting – Why is there Thick, or Thin Liners?
NEDC is an authorized converter for 3M company. For that reason, we often get questions from customers about the adhesive tape products we offer. Customers often ask, what is the difference between this tape, and this tape? The reason customers ask this question, is a...
Application Note for Speaker Gasket Found In Airport
When people ask me what I do for a living, I'll be honest- I struggle trying to tell them what I do. I usually end up just saying, most of the parts we make are for aerospace/military applications. Which is true. However, frankly that is a terrible answer. I'm going...
