Thermal Pad: Efficient Gap Filling and Superior Cushioning for Thermal Management
In the thermal management design of high-performance computing and power electronics, the thermal pad is a key interface material for eliminating thermal resistance and improving heat-exchange efficiency. The thermal pad series from Lixing Composite Materials offers excellent softness, elasticity and high compressibility, effectively filling the tiny air gaps between heat-generating components and heat-sink modules to ensure the stability and safety of electronic products under high loads.
Why Choose Lixing Thermal Pads?
Ultra-soft with high compressibility: With a hardness of only 5 to 40 Shore B, the pad compresses substantially under very low pressure and conforms closely to uneven surfaces, maximizing contact area.
Wide choice of thermal conductivity: Multiple grades from 1.0 W/m·K to 10.0 W/m·K precisely match heat-dissipation needs from consumer electronics to high-power industrial equipment.
Excellent insulation and flame retardancy: Meets the UL 94 V-0 / V-1 flame rating and provides reliable electrical insulation, keeping precision circuits safe.
Vibration damping and protection: The material also cushions well, absorbing mechanical vibration and protecting fragile electronic parts from pressure damage.
Full customization service: Thicknesses from 0.25mm to 1.3mm, with precision die-cutting to customer drawings or convenient roll supply.
