IOTA GNJ 3250N Silicone Gel—The Next-Gen Encapsulant for Power Electronics

Hits: 534 img

As 800V EV platforms and grid-edge computing redefine reliability standards in 2026, IOTA GNJ 3250N sets a new benchmark with ultra-low cyclic siloxanes (D3-D10<50ppm) and self-adaptive curing—engineered for SiC power modules, ADAS electronics, and smart energy systems.

Why Global Innovators Adopt It

  1. Purity Redefined
    • 80% lower cyclic content: GC-MS verified to prevent circuit corrosion (compliant with IEC 61215 & AEC-Q200).
    • Zero exudation: >1×10¹⁵Ω·cm volume resistivity after 3000h damp heat (85℃/85%RH).
  2. Process Intelligence
    • Thixotropic viscosity (2500±500cps): Enables 50μm gap filling for IGBTs with <0.1mm dispensing accuracy.
    • Dual-cure chemistry: 8h@25℃ or 30min@100℃ for JIT manufacturing.
  3. Extreme Environment Ready
    • -55℃~180℃ flexibility: Passes ISO 16750-4 vibration (20G, 1000h) with ΔYI<1.5 after 5000h UV.
    • Self-healing interface: 90% sealing recovery per ASTM D412.

2026 Mission-Critical Applications

  • Next-Gen Energy:
    ▸ 800V IGBT potting (PDIV>20kV/mm)
    ▸ PV optimizer IP68 protection
  • Autonomous Driving 2.0:
    ▸ 4D radar antenna encapsulation (Dk=2.8@10GHz)
    ▸ Zonal compute unit TIM
  • Industrial AIoT:
    ▸ Edge node anti-condensation coating
    ▸ UHVDC sensor insulation

The GNJ 3250N Advantage

✔ Risk Mitigation: 47% lower field failure rate (2025 OEM data).
✔ Eco-Leadership: 30% bio-based content with EPD certification.
✔ Future Compliance: Meets (EU) 2025/1186 recyclability mandates.
