Thermal Interface Gel (TIM GEL EV GRADE)

Description

1. Product Overview
The Thermal Interface Gel (TIM GEL EV GRADE) is a high-performance, dispensable thermal management material engineered specifically for electric vehicle (EV) battery systems and high-density power electronics. It serves the critical function of eliminating microscopic air gaps between heat-generating components and their cooling solutions, thereby reducing thermal resistance by over 85% compared to standard thermal pads. Strategically, this product is indispensable for EV manufacturers seeking to extend battery cycle life, enable faster charging, and achieve IP69K reliability—directly addressing the industry’s highest thermal runaway prevention standards.

2. Key Specifications & Technical Characteristics

• Chemical composition: Non-silicone, hybrid metal-oxide filled polymer (boron nitride / alumina matrix) – silicone-free option available for sensitive electronics

• Purity level: ≥99.5% thermally conductive filler content; ionic impurities <50 ppm

• Physical characteristics:

  • Form: Smooth, non-sagging paste (thixotropic index 4.5–5.2)

  • Color: Gray

  • Particle size: D50 < 15 µm (optimized for <0.2 mm bond lines)

  • Density: 2.8–3.1 g/cm³

  • Thermal conductivity: 3.2 W/m·K (EV Grade)

• Packaging options: 30 cc syringes (automated dispensing), 1 kg cartridges, 20 kg pails, 200 kg drums

• Shelf life: 12 months unopened (18 months with climate-controlled storage)

3. Core Industrial Applications

• Primary industries: Electric vehicle battery pack assembly, power inverter manufacturing, onboard charger (OBC) production, energy storage systems (ESS)

• Specific use cases:

  • Thermal interface between cylindrical/pouch battery cells and cold plates

  • Gap filling between IGBT modules and liquid-cooled heat sinks

  • Vibration-dampening thermal coupling in high-shock EV drivetrains

• Performance superiority: Unlike pre-cut pads, this gel flows automatically under low compression pressure (<10 psi), accommodating ±0.5 mm manufacturing tolerances. It outperforms greases by maintaining <1% pump-out after 2,000 thermal shock cycles (-40°C to 125°C). Cost advantage: 30–40% lower total applied cost vs. ceramic pads due to zero die-cut waste and 50% faster robotic dispensing.

4. Competitive Advantages

• Quality consistency: Lot-to-lot viscosity variation ≤±5% (certificate of analysis per ISO 17025 lab for every batch)

• Supply reliability: Dual-continent manufacturing (Asia & Europe) with 24/7 order fulfillment; <10 days lead time for 20 MT

• Logistics capability: UN-certified packaging; ambient temperature shipping (no cold chain required)

• Price competitiveness: Tier-1 performance at Tier-2 pricing (≤$0.08/gram for contract volumes >10 MT/year)

• Sustainability: 100% solvent-free, RoHS/REACH/China RoHS compliant; low VOC (<2 g/L)

• Technical support: Full thermal simulation model files (CALCE/Siemens format) + on-site dispensing validation included for enterprise contracts

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (MT) per purchase order (sample kits available: 5 kg maximum for qualification)

• BULK 20MT loading capacity: One 20-foot dry container = 20 MT exactly (palletized, 900 kg net per drum × 22 drums; pallet footprint: 48” × 40”)
