GROMMET RUBBER COMPOSITIONS FOR AUTOMOBILE IMPROVED BLOMMING -RESISTANCE AND GROMMET RUBBER THEREOF

摘要

The present invention relates to a grommet rubber composition for vehicles with excellent blooming resistance and to a grommet molded product manufactured by using the same. More particularly, the grommet rubber composition is obtained by enhancing physical properties of ethylene propylene diene monomer (EPDM) terpolymer rubber by using a reinforcing filler, a vulcanizing agent, and a vulcanization accelerator. The grommet rubber composition for vehicles with excellent blooming resistance according to the present invention includes EPDM rubber, 105-380 phr of the reinforcing filler, 0.5-2 phr of the vulcanizing agent, 1-5 phr of the vulcanization accelerator, 1-10 phr of a vulcanization aid, 70-120 phr of a softener, and 0.5- 3 phr of an activator with respect to 100 phr of the EPDM rubber.
