摘要： 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.

摘要： A method for producing a formed product of deproteinized natural rubber latex capable of reducing a content of an allergen in a natural rubber latex material to a level sufficient to keep the latex from being harmful to the human body without decreasing yields of the product and deteriorating formability of the latex. In the method, cleaning removal of a non-rubber content is carried out after each of protein decomposition, prevulcanization and forming. An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02% by weight or alcohol-water mixed liquid containing alcohol in an amount of 5 to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.

摘要： A material for making marine structure comprises a rubber composition. The rubber composition contains a metal salt of .alpha., .beta.-unsaturated fatty acid and is vulcanized in a mold into a predetermined configuration. The strength of the rubber composition is anisotropic and in particular its elastic modulus is anisotropic. The direction in which the strength of the rubber composition is high is set in the direction in which stress is applied by waves. Thus, the marine-structural material is resistant to waves and tide. The rubber composition contains short fibers which are oriented in a certain direction to increase the anisotropy of the rubber composition.
