Abstract :
The present paper reports about the results of a study of mechanical, thermal, dynamic mechanical and electrical properties of polymeric insulators. Silicone rubber, ethylene-propylene-diene monomer (EPDM) and alloys of silicon-EPDM are known polymers for use as high voltage insulators. The result of dynamical mechanical measurement shows that the storage of blends enhanced with increase EPDM in formulation. It can be seen from the result of TGA measurement that initial thermal decomposition of silicone rubber improved in the effected of EPDM in blends. The blends of silicone-EPDM show good breakdown voltage strength compare to silicone rubber. They present also more hydrophobicity in comparison to EPDM.
