Hot-Melt Glue As Insulation?

[The Mighty Volt]

This may sound daft, but can hot-melt glue be melted onto wires to act as insulation? Or will it just melt with the flow of current? It takes a 500w glue gun, which is designed to cause heat, quite some time to get the glue melted.

Thanks.

Melt it on a wire a see if you can measure the ohms.

Wow. I've never heard of a 500w glue gun. Mine is like 60w on high. If your wire is dissipating 500w though, you've got some big problems.

I don't doubt it's insulation qualities...I was just wondering how well it might hold up when I am pulling 100Amps through a 9AWG wire.....could it melt?

Thanks for the hint about the insulation

Parkside cheapo, cost €11. 500w @ 220v. Would melt the ice of a Polar Bears Ba....anyways.

A wire can pull 1000watts and never heat up if it is fat enough.

Usually hot glue melts at 175 degrees F

There are industrial versions that go up to around 500F. A lot in the 250F range. I would not depend upon hot-melt for insulation, but should be OK as a backup insulation in belts-and-suspenders applications.

What I am depending on it for is to take the place of those little insulation grips you see spade end connectors in. I can't get my 9AWG to thread up through them, the entry point is too narrow, so I am subbing in hot glue on the female spade end and finishing it with insulation. Might throw up a picture later, right now my pants are falling down.

How about using some heat shrink? Spade connectors are where I'd avoid low temp hot melt. If they begin to fail, they can get real hot.

Spade connector is maybe a step-up from an anderson for it's size, but seldom are they high current connectors.

This is definately the right application for heat shrink, not hot-glue.

Yep, heat shrink. If you need it beefy, several layers on top of each other.

or use silicone wire
