Vacuum Formed Refractory Shapes

VacuumFormedRefractoryShapes VacuumShapesVariety


Vacuum-formed refractory shapes are used to cast aluminium, ferrous and other metals. They need to be created for high-temperatures and need to be durable enough to continuously be in contact with molten metal. Pyrotek Pyro-Iso vacuum-formed shapes offer excellent insulating properties and strength, combined with low fume generation.
