Parameter

Data

Model Number

QY(F)-2/240

Thermal Class

240 (Up to 260°C Peak)

Insulation Material

Aromatic Polyimide (PI)

Conductor Material

Electrolytic Copper (99.99% Pure)

Diameter Range

0.10 mm – 4.00 mm (Customized available)

Cut-Through Temperature

≥ 450°C

Film Grade

Grade 2 (Heavy build), Grade 1 & 3 available

 Extreme Heat Resistance

Withstands cut-through temperatures up to 450°C, ensuring structural integrity under short-term overloads and high-temperature spikes.

 Chemical & Solvent Resistance

Highly resistant to diluted acids, alkalis, organic solvents, and refrigerants, suitable for hermetically sealed applications.

 Radiation Resistance

Maintains electrical properties even under gamma and beta radiation exposure, ideal for nuclear or medical equipment.

 Mechanical Strength

Superior abrasion resistance and flexibility (Mandrel winding test passed), reducing the risk of insulation failure during high-speed winding.
