When thermal management gets serious, engineers need a gap filler that does more than conduct heat. They need one that conformably fills microscopic air gaps, maintains low thermal resistance under mounting pressure, and stays electrically insulating across a wide temperature range. The T-work7000 thermal pad from LiPOLY delivers all three in a single material.
This ultra-soft thermal pad sits at the entry point of LiPOLY’s Extreme Series. It is designed for applications where minimizing thermal resistance is critical, but where delicate components and uneven surfaces make a compliant, high-compressibility material essential.
Key Specifications of the T-work7000
The T-work7000 is built on a silicone compound platform that achieves a thermal conductivity rating of 11.0 W/m·K (ISO 22007-2, ASTM D5470). More importantly, its thermal impedance comes in at 0.223 °C-in²/W at 10 psi of contact pressure. That low impedance figure is what separates a good thermal pad from a great one. A pad can have high conductivity on paper, but if it does not wet out to the surfaces it contacts, heat builds up at the interface.
The T-work7000 solves this with an ultra-soft formulation that compresses readily under low mounting force. That compressibility allows it to fill voids and microscopic air gaps between a component case and a heatsink or chassis, creating reliable thermal contact without requiring excessive clamping pressure.
Typical properties include:
- Thermal conductivity: 11.0 W/m·K
- Thermal impedance: 0.223 °C-in²/W @ 10 psi
- Surface tack: 2-side or 1-side options available
- Thickness: Customized to application requirements
- Operating temperature: -60°C to 150°C
- Electrical insulation: Excellent
- Flammability: Non-flammable formulation
- ROHS / REACH compliant

Applications for the T-work7000
The T-work7000 targets applications where the thermal path involves slight misalignment, surface roughness, or components that cannot tolerate high clamping force. Typical use cases include:
- CPU and GPU cooling in consumer electronics and embedded systems
- Memory module heat spreading between chips and thermal rails
- Telecom hardware PCBs in base station and networking equipment
- Industrial motor controllers where thermal cycling is common
- LED lighting assemblies requiring stable operating temperatures
Because the T-work7000 is silicone-based, it provides good electrical isolation between live components and heatsinks. This removes the need for a separate insulating washer or sleeve, which simplifies assembly and reduces interface layers in the thermal path.
Die Cutting and Custom Configurations
NEDC supplies the T-work7000 as a custom die-cut part. That means the pad arrives ready to drop into a housing or onto a PCB, sized precisely to the application geometry. No secondary cutting, trimming, or hand fitting is required on the production line.
Die cutting also opens up kiss-cut and tabbed formats for automated placement, which matters in high-volume assembly environments. NEDC can produce T-work7000 in sheets or in individual die-cut parts to specification.
For applications that require a specific durometer or thickness not met by the standard product, NEDC works directly with LiPOLY to source or configure material to the required property set.
Comparing T-work7000 to Adjacent Products
The T-work7000 is the entry point in LiPOLY’s Extreme Series lineup. Stepping up to the T-work8000 increases thermal conductivity to 15.0 W/m·K and reduces thermal impedance to 0.185 °C-in²/W. The top of the series, the T-work9000, pushes to 20.0 W/m·K with an impedance of just 0.110 °C-in²/W.
That progression lets engineers scale thermal performance within the same material family and manufacturing process, without redesigning the thermal interface.
How to Specify T-work7000 for Your Application
Working with NEDC to specify T-work7000 involves sharing the target interface dimensions, the available clamping force, and the operating temperature range. From there, NEDC selects the appropriate thickness and tack configuration. Custom colors, thicknesses, and configurations are available on a per-application basis.
