DOW CORNING production would n o t be available in time to make u p the 300,000-ton deficit. D u r i n g 1956, 139,051 long tons of r u b b e r were exported from t h e United States: GR-S Butyl Neoprene Nitrile

A desire to b e self-contained a n d to avoid being dependent on t h e Suez Canal for deliveries has r e ­ sulted in the planning or actual con­ struction of at least 10 G R - S plants, one Butyl plant, one nitrile plant, and one neoprene plant in Europe. Based on the indicated capacities of these plants, together with t h e capacities of U. S. plants, total world capacities will b e :

have proved their efficiency and versatility in countless applications. For example : 1 OUNCE KILLS F O A M I N . . .

It is seen that there will be a world­ wide shortage of polymers by 1965, although the installed capacity b y t h a t time in t h e United States will b e more than a d e q u a t e to meet U . S. rubber requirements. By 1965, production a n d consump­ tion in the United States should be about in balance b u t the Gulf Coast undoubtedly will have a n excess of both G R - S a n d the r a w materials from which it is manufactured. I m ­ proved methods of transporting r a w materials, particularly gases, will have to be developed. A good start has been m a d e in shipping butadi­ ene by water a n d m a n y other devel­ opments a r e being worked upon. Panel M e m b e r s R . F .
