Oxygen d®esnft always m e a i i i **lAtf©,f Eastman antioxidants are extending t h e useful life of products i n many fields Many p r o d u c t s need p r o t e c t i o n against oxygen. Lard, a typical example, turns rancid a t room temperatures unless protected by the addition of a n antioxidant. "Returns" and complaints of off-flavor and rancidity have long been the bane of vendors of shelled nuts. Today, thanks to the availability of an Eastman antioxidant, nut

processors can practically eliminate such complaints and greatly expand their product's distribution. The longer shelf life made possible by Eastman antioxidants, has likewise helped potato chip manufacturers broaden their selling area. Eastman antioxidants have also helped t o develop a new outlet for inedible fats and oils . . . animal feeds. Added to feed in amounts up to 4 % to 5%, these fats improve the feed and represent a market of 2O0300 million pounds annually. This was a totally new market for fats and helped ease a fat-surplus problem for the meat industry. Yet, it would have been impossible if antioxidants had not been available to stabilize the fat and keep the feeds fresh and palatable. E a s t m a n a n t i o x i d a n t s protect many different food products, but an even broader field is covered by their use in industrial products. In gasoline and motor fuels, antioxidants made by Eastman protect against the formation of powerrobbing gum. I n transformer and turbine oils,

Eastman antioxidants extend service life by preventing the quick breakdown that might otherwise occur at the high working temperatures encountered. In plastics, Eastman antioxidants help stabilize plasticizers for vinyl resins-and are also used to protect polyethylene against deterioration during molding and extrusion and upon extended exposure. In rubber, antioxidants play a well-known role in protecting against aging and heat deterioration. Rubber also needs protection against ozone — one of the most powerful oxidizing agents known. Even t h e minute concentration of ozone in the atmosphere can severely damage rubber products. To combat this attack, Eastman antiozonants are available. In the agricultural field Eastman antioxidants are extending the effectiveness of such important pesticides

creasing the utilization of Vitamin A from carotene and safeguarding chicks against such deficiency diseases as encephalomalacia. This list could be continued to show that whenever oxygen poses a destructive threat to organic compounds there is a good chance that an Eastman antioxidant is available for effective counter measure. Perhaps one of the many antioxidants made by Eastman could help you add life to some product you

make or use. Perhaps, as the foregoing examples illustrate, one of these antioxidants could help you combat rancidity, bad odor, off-flavor, loss of nutrient value, discoloration, embrittlement or aging:. Eastman antioxidants have helped many c o m p a n i e s extend present markets and even develop new markets. If your product —be it food, agricultural or industrial—needs pro-* tection against oxidative deterioration, call in Eastman. Eastman's food and industrial antioxidant laboratories are staffed with specialists anxious to help you explore the benefits, the use, and the cost of antioxidants.
