Show NEW FILM SENSATION Eight pears of chemical research have resulted in the development of "Cronar,"' a radically new petrochemical pet-rochemical base for photographic film. "Cronar" is - related chemically chemi-cally to the' miracle' fiber "Dac-ron," "Dac-ron," and to "Mylar," another oil-based oil-based plastic film., The new film base does- not shrink, ' is extra strong-a 35-mm strip can tow ah automobile.- While standard - film will break after about 40 flexings, "Ci'onar," which is only two-thirds as ,-thick, can be flexed 15,000 times without splitting. Besides its applications in the motion picture and television industries, oil-based "Cronar" will be used in airplane gun" cameras and other aerial photographic pho-tographic equipment. Oil furnishes raw materials "for products' and processes that serve ' in business, industry, and homes throughout America. |
