Insulating and structural materials at ~GHz

Insulating and structural materials at ~GHz

Insulating and structural materials at ~GHz

This is a duplicate of a question asked on the Other Topics forum:

What is the best insulating material to use at these frequencies? I'm thinking about a material to bind copper wire strands together. Ideally the material should have good mechanical properties, as well as no UHF heating (or shielding).

My first thought was epoxy-resin, since this allows me to position the wires first before setting. I'm willing to consider other plastics, but am keen to avoid expensive injection mold tooling. I have used Nylon in the past, since this can be machined. A friend has even suggested glass or carbon reinforced resin, since these are very robust for a given weight.

Does anyone have any ideas/suggestions?


RE: Insulating and structural materials at ~GHz

EA956 dual part epoxy is really low loss.
I put a sample in a microwave oven for 2 minutes with virtually no heating noticeable. It's tough mechanically too.
