Not sure what your replacing if it is a round insulator piece for 2 pipes or stand off type insulator for matching section or what?
Try fiberglass rod material or Teflon blocks depends on application. Teflon blocks were used on heavy industrial equipment when shipped so the equipment can be slide over the floor.
