Product Description

SI1125 2.5w/m.k RTV lubricant silicone silicon thermal conductive grease

SI1125 is thermally conductive material used in electronic equipment, with excellent thermal conductivity. With its low viscosity, can make the components surface closely contact with the radiator and reduce the thermal resistance, can quickly and efficiently lower the temperature of the electronic parts, so as to prolong the service life of electronic components and enhance its reliability. SI1125 Thermal grease would not cross linking, so if there are any changes in the process of electronic assembly or replace the radiator happens, this product has the characteristics of easy operation. In addition to the high thermal conductivity property, also do not generate stress when using, high stability under -50 to+200 °C, and has excellent weatherability, radiation resistance and excellent dielectric properties.

Key Features

1.Excellent thermal conductivity 2.5W/(m·K)

2.Low sedimentation, room temperature stored

3.Excellent high and low temperature resistance

4.Excellent weatherability, radiation resistance and dielectric properties.

5.Excellent chemical and mechanical stability

Typical Applications

Widely used in LED, MPU, DIMM, Cached DRAM, DC/DC Convertors, integrated chip, semiconductor, power module, power semiconductor, solid-state relay, bridge rectifier, automotive electronics, telecom equipment, Computers and accessories, etc.
