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.
