DOWSIL™ TC-5080 High-Performance Thermal Grease: Optimized Thermal Interface Solution for Electronics Cooling

Basic Product Properties

DOWSIL™ TC-5080 is a one-part, white, non-curing thermal grease composed of thermally conductive fillers and a siloxane polymer matrix, delivering 1.0 W/mK thermal conductivity with high-temperature stability.

Product Description

Formulated with metal oxide-filled silicone technology, this material creates an efficient thermal bridge between heat sources and heat sinks. Its low thermal resistance reduces interface temperature gradients, enhancing cooling efficiency and long-term reliability for PCB assemblies, particularly in compact electronics.

Key Performance Attributes

High-Temp Stability: <0.01% oil bleed at 150°C/24hrs guarantees reliability under prolonged thermal stress.

Low Thermal Resistance: 836,000 cP viscosity with 4.5mm slump enables ultra-thin Bond Line Thickness.

Electrical Safety: 8.7 kV/mm dielectric strength and 2.9×10¹⁵ Ω·cm volume resistivity ensure circuit protection.

Validated Applications

• 5G Base Stations: Thermal interface for Nokia AirScale RF units (-40℃~150℃)
• EV Power Systems: Cooling solution for Tesla OBC power modules (Mass production validated 2022)

• Consumer Devices: Chipset cooling in Microsoft Surface Pro motherboards (0.2mm BLT compatibility)
