FIELD: technological processes.
SUBSTANCE: disclosed is the effective thermal paste composition comprising the super-branched olefinic fluid and heat conducting filler, and its preparation process. Also, the said thermal paste may include modifying properties additives and fillers. Super-branched olefinic fluid is selected so, that it contain at least 1.5 of methine carbon atoms in the oligomer molecule and at least 40 of methine carbon atoms per total carbon thousand atoms. Claimed thermal paste has flash-point of 180 °C or higher, flow temperature of 0 °C or lower, and kinematic viscosity at 40 °C of not more than 200 cSt (0.0002 m2/s).
EFFECT: said thermal paste composition can provide improved thermal conductivity, less propensity to movement and lower cost in comparison with many other thermal pastes, including the silicone-based thermal pastes.
