Flat resistive ribbon made from NiCr 80/20 (80% nickel, 20% chromium). Built for resistance heating and hot cutting: thermal stability, fast response, low oxidation, and long service life at high temperatures. The flat profile spreads heat better than round wire for clean cuts and consistent seals.

Applications

• Cutting polystyrene (EPS/XPS) and foams with hot knives/bows.
• Heat sealing plastic bags (PE, PP, laminates) in impulse or continuous sealers.
• Spot-welding battery packs (resistive strips, tooling, preheating).
• Flat heaters for 3D printers, thermal chambers, molds/thermoforming, and prototyping.

Benefits

• Even heating from larger surface area.
• High oxidation and creep resistance.
• Stable under pulsed duty.
• Easy to form and mount.

Specifications

• Widths: 3, 4, 5, 8, 10 mm.
• Thicknesses: 0.10, 0.20, 0.30 mm.
• Material: NiCr 80/20 (flat ribbon).
• Finish: smooth edge.

Recommendations

• Use tensioners/guides to keep the ribbon straight.
• Insulate clamps and control via SSR/PWM.
• Increase power gradually to target temperature.
• For batteries, follow safety best practices.

The maximum length in a single piece is 5 meters. (Example: if you order 7 meters, one 5-meter roll and one 2-meter roll will be sent.)
