Show NEW RUBBER RUB run 4 ER TIRES FROM OIL MARK RESEARCH ADVANCES one of these days day we ma may be riding on tires tire which last ai as tong long iong i as the cars we owal thia nit bright prospect 1 Is held out by the re c cent en t devo deve development loument of an economical process for making more and better synthetic rubbers at low temperatures until this year the manufacture of synthetic rubber was a tedious job requiring high temp era cra chatum tures and a reaction time of f as much as 30 hours the aw new cold coid process employs temper temperatures ranging between 14 de grees arees above and four derees dences below zero and manufacture is complete within a time range of 75 minutes to five hours present plans call for half of the annual united states prad production uc of tons of synthetic rubbers to be bp made by the cold process within the near future tomo tomorrows tires what will the tires of tomorrow be made of ofa well the inner tube tubes if there nrc arc any probably will consist of a petroleum product called butyl such tubes already have won widespread public favor because they dont leak even when pounded over the worst roads and can crin bo be manufactured to run for nilles miles after being punctured rire trends treads arr ids may be manufactured wholly or partially from another petroleum synthetic called buna bunn S or GR S these came into use during the war they show amazing resistance to wear and when made X by the new cold process resist chipping c dipping and cutting better than tires made entirely 0 f natural rubber eventually it is hoped they will run miles tire si dewalls probably will be of rita natural tural rubber which if i better than any synthetic so far developed in its flexibility and resistance to heat caused b by friction and tire fabrics gilr will more than likely be wolen from nylon Be search research responsible nible with all of their super qua I 1 ties it appears that such tir tires may sell at or even below t the price of first class prewar natu r ral rai al rubber prototypes this is so because cold process rubber can be manufactured right now at a cost competitive with that of the natural product production ibri I 1 the new tires and thousands of other useful products made from synthetic rubber are coming to us as the result of a brilliant job of research and development they are a monument to the initiative of free enterprise in the face of an emergency that is because they are the outgrowth of efforts which played an important part in winning the second world war and in changing the face of the postwar world the main constituent of almost all synthetic rubbers is is a petroleum byproduct by product called butadiene which also can be made from grain alcohol alco aico tires will vary many new forms of rubber have since been developed as the result of peacetime competition between the 50 petroleum rubber and chemical companies working in this field the new cold process tires put out by various companies will vary in characteristics each will incorporate special features but will draw upon the vastl vasil vast rund of wartime experience which joint re search created thus research and develop ment carried on in common by oil rubber and chemical companies anies during the war is playing playing ever even increasing peacetime div dividends to the public |
