Thermal Grease: Extreme Temperature Resistance and Low Thermal Resistance Gap Filling
The thermal grease (silicone-based) from Lixing Composite Materials offers high thermal conductivity, low thermal impedance, excellent insulation and stable working performance. It suits the heat dissipation needs of all kinds of electronic components, with a wide operating temperature range from -40°C to 250°C and momentary temperature resistance from -50°C to 340°C.
Product Features
Efficient heat transfer: Available in multiple grades from 2-10 W/m·K, with very low thermal impedance for rapid heat transfer.
Outstanding temperature resistance: Stable operating temperature from -40°C to 250°C, with momentary resistance up to 340°C.
High-grade insulation: Volume resistivity of 10^14 Ohm-cm keeps precision circuits safe and prevents any current leakage.
Stable and non-flowing: High viscosity and extremely low evaporation; it does not dry out, crack or fail under long-term high temperature.
