| Abstract: |
| Silicone rubber compounds of high voltage cap and wedge for color TV set have been developed. The effect of flame retardant and filler on the physical properties，flame retardance and electrical properties is investigated. The results show that a good flame retardance is obtained with Sb2O3/DBDPO blend flame retardant system；3～4 phr of silica is adequate. The resultant formula is as follows：silicone rubber（151 mix type） 100；2，5-dimethyl-2，5-bis（tert-peroxy）hexane 1；Sb2O3 2；DBDPO 4；silica 4 and 3 respectively for high voltage cap compound and wedge compound. |
