Resistance wire is used as a hot cutting wire for the accurate cutting of complex shapes from polystyrene foam (EPS) and extruded polystyrene (XPS). Depending on the application, the resistance wire is generally a special nickel alloy or stainless steel and is heated to approximately 200°C by electrical resistance.
Hot wire cutting is used extensively in the packaging industry and for cutting shapes for R&D prototyping, modelling and architectural mouldings.

Material
Physical & Service Properties
ORW - L
Good heating characteristics and easily bent to shape for hand cutting of patterns.
ORW - M
Moderate strength and low electrical resistivity are utilised for low heat applications.
ORW - H
Good heating characteristics in a medium strength wire.
ORW - EH
High strength at elevated temperature, with good creep resistance. The best general purpose cutting wire.
ORW - S
The highest specification cutting wire. Very high strength at elevated temperatures, with high creep resistance.
