Abstract
This invention presents a rubber composition wherein a determined amount of protein is mixed with unvulcanized rubber. Rubber products made of this rubber composition have sufficient strength for practical use and are harmless to human bodies. The rubber composition of the invention not requiring vulcanizing process is advantageous in eliminating the need of large-scale vulcanizing equipment. Combined use of a curing agent and protein will increase modulus higher than using the curing agent alone.
