NiCr 80/20 resistive wire for hot-wire cutting of polystyrene (EPS/XPS, foam, Styrofoam®).

Also called heating/resistive wire.

Offers thermal stability, low oxidation, and long life under continuous or pulsed duty (SSR/PWM).

Works with bows, knives, and CNC/DIY hot-wire tables.

Applications
EPS/XPS cutting/shaping (3D letters, models, sets, packaging); technical foams, thin thermoplastics; linear heating elements.
