Abstract
PURPOSE: A rubber composition that is made by adding a cyclopentadiene petroleum resin to ethylene-propylene-diene terpolymer rubber, thus improving the processability before vulcanization and physical properties after vulcanization, especially the mechanical hardness at high temperatures.
CONSTITUTION: To 100 parts by wt of ethylene-propylene-diene terpolymer rubber are added 4W40, preferably 5W30 parts of a petroleum resin that has lower than 150°C, preferably lower than 130°C softening point, 500W5,000 molecular weight, 50W250, preferably 60W220 bromine value and mainly contains cyclopentadiene or dicyclopentadiene.
