Malcolm,
	yes it is more versatile. Don Lancaster, of TTL cookbook fame,
suggest using 12mm (1/2") polyethylene rod in a hot glue gun for small
scale  injection molding. 

I believe that hot glue is basically a type of polyethylene, but I
have not called 3M about it yet. Old memory says that yes polyethylene
is polar, but don't quote me.

Why not get a temperature controlled pot, and melt up some
polyethylene. Then pot you components in it.
