Vinyl Mould Rubber  (Yellow)
(You are purchasing 500 gram lots of which will be cut from the shown Billet if you want 1 kilogram purchase 2 units)

Re-meltable Vinyl  Mould Rubber,  often known as Vinamold or Gelflex etc. This material is used where the mould is not required for long service and so can be reused many times. It's main disadvantages are:- The pattern or "plug" that is to be moulded has to be able to withstand the temperature (130C) of the rubber.  (porous objects tend to blow bubbles). Also it requires a temperature controlled melting pot

I melt mine in a microwave on a low power setting in a pyrex jug.
