Blue Gelflex moulding compound.

Gelflex is a remeltable PVC moulding compound that forms a flexible mould. It has good tensile strength and is very flexible, allowing castings with deep undercuts, ideal for castings made from plaster and concrete.

• Pack size: 1kg
• Semi-flexible grade.
• Melts at 130°C / 135°C and is poured over suitable masters.
• A release agent is not normally required.
• Pot life: 3-4 mins

• Information sheet (1.5Mb PDF).
• Please note: the manufacturer is no longer producing Gelflex, once we’ve sold out, we will not be able to re-stock.

A major advantage is that when the mould is worn or requires replacement, it can be cut up, remelted and reused.

PLEASE NOTE: The manufacturer has discontinued this product. We managed to source the last of their supplies, but it comes as a single block. The product is exactly the same, just not segmented as before. It can easily be cut with a clean blade.
