Abstract
PARACON is a new type of elastomer which has been developed by Bell Telephone Laboi atones to help meet the present rubber shortage. While it is a war baby in that the present crisis furnished the impetus for its adaptation for practical use, the first samples were prepared long before Pearl Harbor, as a byproduct of peacetime telephone research. In common with other synthetics, it simulates many, but not all, of the characteristics of natural rubber, and in comparison with; other rubbers it has some distinct advantages and some definite limitations. It looks and feels like rubber and in strength and elasticity it compares favorably with some of the other synthetics. For example, the tensile strength of properly compounded stock in general averages about 1,700 pounds per square inch but certain experimental compounds have shown values as high as 3,000 pounds per square inch. The elongation at break in some cases is as high as ...
