Thiokol is an elastic plastic made by Dow Chemical Co. Its merits as a retread material, hitherto overlooked, were enthusiastically presented to WPB last week by an authoritative group of experts from the rubber, chemical and automotive industries, headed by famed Research Engineer Charles Kettering of General Motors. They told the Government that Thiokol...
...Will wear at least 5,000, probably 10,000 miles on cars driven no more than 40 m.p.h. Though Thiokol is not quite so strong or wear-resistant as natural rubber, it does not deteriorate with age or from exposure to air, sunlight...
Thiokol itself is not brand-new. It was accidentally discovered in 1929 by a chemist who was trying to concoct an antifreeze. Since 1930 it has been manufactured as a substitute for rubber, leather, cork. Typical uses: barrage balloon coatings, gas masks, gasoline hoses, washers, cable sheathing...
...nobody thought of Thiokol as a retread material until Kettering and the Society of Automotive Engineers last April set out to explore every possible form of rubber synthetic and substitute. They pried into the deepest competitive secrets of U.S. rubber processors without finding a quick, cheap answer to the tire problem. Then they called in the U.S. chemical manufacturers, again examined every possibility. Only one appeared good: Thiokol. To test its usefulness, they crowded a year's research into the last two months...
Lumber stocks on June 6 were only 2.6 billion board feet, against 3.1 billion a year before. Prospect now is that civilians will soon find lumber almost as hard to buy as rubber...
