Gelflex Hot melt Vinyl is a PVC moulding material which can be re-used many times. Available in two grades it provides an extremely cost effective alternative to more expensive materials, such as silicone and polyurethane and produces good results.


So the advantage is that after the mould has been used it can be cut up and reheated and melted down again for use in another mould.


Over the years Gelflex has become very popular for use in creating wax models for use in the lost wax process for bronze casting and glass casting. It is also used when casting plaster and concrete.


Gelflex should be melted using a simple thermostatically controlled heating vessel to avoid overheating – we stock a range of Melting Pots for this purpose. Gelflex should be heated to between 150 °C and 165 °C.


Gelflex Grades:

Hard grade - Blue, 13° Shore A

Soft grade - Beige, 8° Shore A


There are two important points to remember when using Gelflex: 1, Efficient sealing of porous masters made from materials such as plaster, concrete & wood; and 2, heating and pouring of Gelflex at the specified temperatures, this stops air-bubbles, shrinkage of the mould and increases the number of possible re-melts.
