UL Certified Dual-Side Corona Treated Polyimide Film 12.5-125μm

This a Dual-Side Corona Treatment polyimide film (PI film) with UL certification, cast polyimide film, Thickness Range 12.5μm–125μm.

1. Premium Performance for Demanding Applications

Our cast polyimide film delivers exceptional thermal stability (up to 180°C continuous), superior dielectric strength (>200 kV/mm), and outstanding mechanical toughness for the harshest environments. Designed for critical electrical insulation in traction motors, wind turbines, transformers, and heavy-duty industrial equipment, it ensures reliability under extreme thermal, electrical, and mechanical stress.

2. Dual-Side Corona Treatment: Unmatched Adhesion & Processability

Both surfaces undergo precision corona treatment, significantly enhancing bond strength for laminates, resins, and coatings. This key feature:
✔️ Eliminates delamination risks in multi-layer insulation systems
✔️ Boosts coating uniformity for magnet wires and encapsulated components
✔️ Streamlines manufacturing with reliable adhesion—no extra surface prep needed.

3. Certified Safety & Global Compliance

UL 94 V-0 certified for flame resistance and UL-recognized component, meeting the strictest international safety standards. Ideal for applications requiring:
✅ Hazard prevention in mining/energy equipment
✅ Compliance with IEC, NEMA, and ISO insulation norms
✅ Auditable quality for export-driven industries

4. Precision Engineered for Industrial Efficiency

• Thickness Range: 12.5μm–125μm (±4μm tolerance; different thickness, different tolerance)

• Width Options: 520mm, 1000mm, 1040mm (customizable)

• Flawless Surface: Zero pinholes, bubbles, or contaminants

• Consistent Roll Quality: Tight winding, splice-free upon request
