What Is DuPont Kapton Film?
DuPont Kapton film is a premium polyimide film manufactured by DuPont, the original inventor of Kapton. It is engineered to deliver consistent, high-performance thermal/electrical insulation across extreme environments, with different types (grades) optimized for specific industrial use cases.
Complete List of DuPont Kapton Film Types (Classification)
Core DuPont Kapton film types and their core purpose:
- Kapton HN: Standard general-purpose grade (balance of performance/cost for basic insulation).
- Kapton FN: Flame-retardant grade (UL 94 V-0 rated for fire safety-critical applications).
- Kapton CR: Conductive grade (carbon black additive for static dissipation/EMI shielding).
- Kapton MT: High-modulus grade (enhanced tensile strength for mechanical stress + high temp).
- Kapton FPC: Flexible circuit grade (ultra-thin, high flexibility for FPCs/flexible electronics).
Technical Specs of Each Kapton Type (Parameters + Data Source)
Spec comparison of DuPont Kapton film types (Data Source: DuPont Kapton Product Catalog 2026):
| Type | Tensile Strength (MPa) | Temp Range (°C) | Key Feature | Flame Rating |
|---|---|---|---|---|
| Kapton HN | 138 | -269 to 260 | General-purpose insulation | UL 94 HB |
| Kapton FN | 138 | -269 to 260 | Flame-retardant | UL 94 V-0 |
| Kapton CR | 120 | -269 to 260 | Conductive (10³-10⁶ Ω/sq) | UL 94 HB |
| Kapton MT | 200 | -269 to 260 | High mechanical strength | UL 94 HB |
| Kapton FPC | 130 | -269 to 260 | Ultra-thin (0.025mm max) | UL 94 HB |
Applications for DuPont Kapton Film Types (Applications)
Optimal use cases for each DuPont Kapton grade:
- Kapton HN: Industrial wiring insulation, general electronics (cost-effective standard).
- Kapton FN: Aerospace cabin wiring, EV battery packs (fire safety compliance).
- Kapton CR: Semiconductor wafers, sensitive electronics (static control).
- Kapton MT: Aerospace engine components, industrial machinery (mechanical stress + high temp).
- Kapton FPC: Foldable phones, wearables, flexible PCBs (ultra-flexibility).
How to Select DuPont Kapton Film Type (Selection Steps)
Follow these steps to choose the right DuPont Kapton grade:
- Identify core need: Fire safety (FN), static control (CR), strength (MT), flexibility (FPC), or standard (HN).
- Check mechanical stress: Choose MT if the film faces bending/tension + high temp.
- Evaluate cost vs performance: HN is cheapest; FN/MT/CR cost 15-30% more (only if needed).
- Verify thickness: FPC grade only available in 0.025-0.05mm (ultra-thin).
- Confirm supply: Ensure your grade is in stock (HN/FN are most readily available).
FAQs About DuPont Kapton Film Types (FAQ)
Q: Is Kapton FN more expensive than Kapton HN?
A: Yes—Kapton FN costs ~20% more than HN (due to flame-retardant additives). (Source: DuPont Price List 2026)
Q: Can Kapton MT replace Kapton HN for general use?
A: Technically yes, but it’s unnecessary—MT’s higher strength comes with a 30% price premium. (Source: DuPont Application Guide)
Q: What is the thinnest DuPont Kapton FPC film?
A: Kapton FPC is available in 0.025mm (1mil) thickness (optimal for ultra-flexible circuits). (Source: DuPont FPC Datasheet)
Summary & Contact Information (Summary + CTA)
DuPont Kapton film types are optimized for specific needs: HN for standard use, FN for fire safety, CR for conductivity, MT for strength, and FPC for flexibility. Choosing the right grade avoids overpaying and ensures optimal performance.
