I have a thin nichrome wire that will be heated up to approx 100 degrees C, inside an enclosure. Since this wire needs to follow a specific path I would like to attach it somehow at some points along that path. Now my question is what material I could use to wrap the wire at those points as to limit the amount of heat dissipated through direct contact at those points.
When looking on the internet I found plenty of insulation materials that can resist high temperatures, but their main purpose is to insulate the electricity going through the wire, not the heat radiated from it. I would need a material that blocks as much heat as possible so the outside would be as cool as possible. This to avoid having all the heat from the wire transferred through the attachments into the plastic of the enclosure, which could melt the plastic at the attachment point. Maybe ceramic can be used for this?
What I was thinking about doing was put some insulation around the wire above the attachment point and clamp the insulated wire to the attachment point. If I were to clamp the wire directly, using bolts and nuts for instance, the heat transfer from the wire through those bolts and nuts would heat up the plastic way too much and it would start getting soft.
Since I am 3d printing my enclosure I can use plastic that can withstand 80 degrees (printing with PETG), which is clearly not enough for this case. Even using nylons I can only go up to 110, which is too close to the wire temperature.
