Abstract:The typical theory model and thermal conducting mechanism of therm al conductive silicone rubber were summarized. Meanwhile, the present status of therm al condu-ctive silicone rubber in country and overseas was introduced in detail. Silicone rubber matrix、fillers and process technology were main facts which defined the therm al conductive properties of silicone rubber. However,the conductive properties,adding volume and dissipation types of fillers were critical facts.
