Dupont Nomex 410 Insulation Paper | High-Temperature Aramid Electrical Shielding Sheet - Genuine Dupont - STK
STK's Genuine Dupont Nomex 410 is the world's leading professional standard in high-temperature electrical insulation paper. Made from pure synthetic aramid fibers, this dense, smooth paper sheet is engineered to provide unbeatable electrical isolation inside heavy-duty motors, generators, and transformers.
Unlike standard plastic films or cheap insulation papers that melt, crack, or release smoke when they get hot, Nomex 410 behaves like an armor plate for electricity. It handles massive electrical voltage loads without breaking down, stays perfectly strong under extreme hot temperatures, and delivers lifelong safety protection for high-voltage industrial equipment.
Product Features
Class H Temperature Rating
Designed for continuous operation in high-temperature electrical environments up to 220°C insulation class requirements.

Electric Motor Slot Liners: Lining the metal slots inside electric car motors and heavy industrial pumps to separate copper wires from the iron frame.
Transformer Wrap Insulation: Wrapping around high-voltage coils and separating primary/secondary copper windings inside power grid transformers.
Generator Phase Barriers: Acting as a safe physical separation sheet between different electrical phases inside large wind turbines and gas generators.
Battery Pack Thermal Barriers: Serving as flame-retardant heat shields between high-power cell modules inside energy storage systems.
Direct Factory Processing Perks
Precision Roll and Ribbon Slitting:
Do you need wide sheets for big transformer wraps, or ultra-narrow strips (like 15mm or 30mm) for automated motor coil winding? Our automated single-knife cutters slice Nomex cleanly with zero fuzzy edges.
Custom Die-Cut Liners & Pads:
We can stamp, score, and bend Nomex 410 into exact pre-shaped slot liners, washers, or custom flat gaskets based on your engineering CAD drawings for rapid factory assembly.
True Direct Wholesale Pricing:
We skip the local middle traders to provide international manufacturers with direct volume-tiered contract pricing, ensuring your component budgets stay highly cost-effective.
