BACKGROUND
Resin composites may be used in a variety of dental applications including as resin filler material for cavities. Over time, thermal and/or mechanical stresses may cause micro-cracks to develop in the resin filler material. Stresses may arise because of strong occlusal (chewing and
The present invention relates to a vulcanized rubber composition and a rubber vibration insulator. More particularly, it relates to a vulcanized rubber composition obtained by vulcanizing a modified ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber composition having excellent fatigue
