ELANTAS’ advancements in thermal conductive materials for electrical insulation—a crucial factor in improving performance and efficiency across various electrical and electronic applications.
Key Applications & Solutions
Impregnating Materials
✅ Used in motors to enhance electrical properties & heat dissipation
✅ Common resin: Pedigree® 8183 unsaturated polyester (0.2 W/mK thermal conductivity)
✅ Advances in nanomaterials and selective fillers achieve 0.3 – 0.5 W/mK
✅ Future thermosetting materials under development targeting 0.4 – 0.8 W/mK
Encapsulants
✅ Provide vibration & moisture resistance for electrical components
✅ Improve thermal conductivity for thick film encapsulation
✅ ELAN-Cast® P 300 filled unsaturated polyester: 0.6 – 2.0 W/mK
✅ Epoxy-based encapsulants: Reach 2.0 W/mK with optimized viscosity
ELAN-Film® Insulation (Motor Slot Liners)
✅ Replaces Aramid fiber papers, improving thermal & electrical properties
✅ ELAN-Film®: 0.20 W/mK thermal conductivity vs. Aramid paper’s 0.18 W/mK
✅ Requires only 3 mils of material to achieve 10,000V dielectric breakdown
Thermal Interface Materials (TIM) – Gap Fillers & Pads
✅ Silicone-based TIMs: High thermal stability & ease of handling
✅ Acrylic TIM pads: Lower thermal properties, mostly thermoplastic
✅ Polyurethane TIM pads:
- Higher mechanical strength vs. silicone
- Minimal outgassing (avoids hardening or contamination)
- Thermal conductivity range: 1.0 – 4.5 W/mK
