Compare Favorably with Octyl esters of the new U.S.I, ISOSEBACIC Acid have been evaluated agains t accepted vinyl plasticizers in a complete series of tests a t the U.S.I, laboratories. The performance results, expressed as relative rat ings above, have been cou­pled with current price indexes to show comparisons which a r e meaningful to the maker of vinyl plasticizers. Here a re the conclusions:

The octyl isosebacates are less expensive than sebacates and closely competitive in overall performance. They have an edge over azelates on cost and are about equal in per ­formance. While comparing· closely on cost with the adipates, they a re better on overall performance. On specific proper­ties, such a s heat stability and resistance to extraction by vegetable and mineral oils, the octyl isosebacates a r e supe­r ior to other low-temperature vinyl plasticizers.

ISOSEBACIC Acid is a new synthetic intermediate made by

Other Vinyl rlasticizers U.S.I. — a mixture of the three C-10 dibasic acids: 2-ethyl suberic, 2,5-diethyl adipic and sebacic acids. I t is not subject to t he price fluctuations unavoidable with r a w materials derived from na tura l products.

This valuable new intermediate will be available soon in commercial quantities from a new U.S.I, plant a t Tuscola, 111. Now is a good time to evaluate ISOSEBACIC Acid as a raw material for your operation. Send for pilot plant samples and technical da ta bulletins.
