Power electronics operate under thermal stress that consumer devices rarely encounter. High current means high heat flux, and the thermal interface material separating a power module from its heatsink must handle both high heat load and the mechanical stress of thermal cycling. The T-work8000 thermal pad from LiPOLY is positioned for exactly this challenge.

T-work8000

Sitting in the middle of LiPOLY’s Extreme Series lineup, the T-work8000 delivers 15.0 W/m·K of thermal conductivity in a formulation engineered for high compressibility and low thermal impedance. It is a step up in performance from the T-work7000, and it targets applications where heat density is too high for commodity thermal pads but where liquid thermal solutions are not viable.

T-work8000 Specifications

The T-work8000 is a silicone-based thermal gap filler rated at 15.0 W/m·K (ISO 22007-2, ASTM D5470). The critical figure for power electronics designers is the thermal impedance: 0.185 °C-in²/W at 10 psi of contact pressure. This low impedance reflects the material’s ability to wet out against mating surfaces under relatively modest clamping force, which matters when the mounting features in a power module cannot handle excessive load.

Typical properties:

  • Thermal conductivity: 15.0 W/m·K
  • Thermal impedance: 0.185 °C-in²/W @ 10 psi
  • Surface tack: 2-side or 1-side options
  • Thickness: Custom die-cut to specification
  • Operating temperature: -60°C to 150°C
  • Electrical insulation: Excellent
  • Non-flammable: Yes
  • ROHS / REACH compliant

The T-work8000 shares the same Shore OOO hardness rating as the T-work9000, placing it in the ultra-soft category. That softness means it conforms to surface irregularities and handles coplanarity issues in multi-component thermal assemblies.

Applications Where T-work8000 Excels

The 15 W/m·K rating puts the T-work8000 in the sweet spot for a range of mid-to-high power applications:

T-work8000
  • DC-DC converters and power supplies where MOSFETs and inductors share a thermal plane
  • EV battery management systems where thermal uniformity across cells prevents hot spots
  • Motor drives and inverters in industrial automation equipment
  • Telecom rectifiers and power amplifiers in 5G infrastructure
  • Server rack power modules with sustained high thermal loads

In each of these cases, the T-work8000’s silicone base provides the dielectric strength needed to isolate electrically live components from grounded heatsinks, removing the need for a separate insulating layer in the thermal stack.

T-work8000 and the LiPOLY Extreme Series

The T-work8000 is the mid-tier option in the Extreme Series, a family of thermal gap fillers built on the same silicone platform and available in die-cut form through NEDC.

If you are working with lower thermal load, the T-work7000 provides 11.0 W/m·K with 0.223 °C-in²/W impedance at a lower price point. At the high end, the T-work9000 reaches 20.0 W/m·K with an impedance of just 0.110 °C-in²/W, suitable for the most demanding AI accelerator and high-power RF amplifier applications.

Scaling within the series means you can maintain the same die-cut geometry and supplier process while upgrading thermal performance. That simplifies qualification and keeps the supply chain predictable.

Custom Die-Cut Supply Through NEDC

NEDC converts T-work8000 into custom-configured parts using die-cutting, waterjet cutting, and laser cutting depending on the material thickness and geometry. This means the pad arrives at your production line as a ready-to-place part, sized to the housing, PCB feature, or heatsink pocket it was designed for.

Kiss-cut tape-and-reel formats are also available for automated pick-and-place assembly. NEDC’s engineering team can advise on optimal thickness selection based on the available gap and clamping force in the assembly.
