Show SYNTHETIC RUBBER OUTWEARS NATURAL Tire treads made from a new synthetic rubber will outwear the best natural rubber "possibly by as much as 30," according to one of the big rubber companies. Enlarging on how American industry in-dustry has continued improving the synthetic rubber produced in the war emergency, the company said the new variety is made by the polymerization of butadiene and styrene at lower temperatures than previously used. "This looms as the most important im-portant development in synthetic rubber research since GR-S, the original general-purpose synthetic, was put into production," it was added. Rubber experts say the implications implica-tions of the new synthetic are world-wide. |
