Colwell - Tarrytown ' ; N0'J Ir ,r` is.- A >/ We have received two similar requests for recommendations involving polyvinyl chloride formulations for injection molding automobile steering wheels. One has come to Bound Brook from our customer "Swedish Crucible" who will supply Chrysler Corporation. We have three potential PVC compounds which could be used, all based on our QYTQ-7 PVC resin. This is a "prior sanctioned" resin which we use in food contact applications. The formulations of our candidates are as follows; QYTQ-7 Flexol DOP Flexol EPO Vanstay RRE Stearic Acid Atomite QNDA-9096 43.7% 36.0 3.0 2.0 0.3 15.0 100.0% di (2-ethyl hexyl) phthalate Ba/cd/zn phenate + chelator Calcium carbonate filler QYTQ-7 Flexol DOP Trlbase Calcium Stearate Atomite Mineral Oil VND-9322 48.5% 33.0 2.0 1.0 15.0 .0.5 100 Tribasic lead sulfat , oiled ucc 063572 -2- QYTQ-7 Flexol DOP Flexol EPO Hark LL Mark C Stearic Acid Mineral Oil Purecal "0" Flexol 10-10 Bisphenol A QNDC-9976 55.80% 25.60 3.00 1.50 0.50 0.20 0.25 6.50 6.40 0.25 Ba/cd phenate Phosphite chelator Precipitated calcium carbonate filler Diisodecyl phthalat Almost simultaneously a request came to Tarrytown for recommended PVC resins and Flexol plasticizers to be used for an injection molded automobile steering wheel. The resin of choice would be QYTQ-7 and the preferred plasticizers would be Flexol DOP, Flexol 1010 and Flexol EPO. We would appreciate your comments regarding use of these products in steering wheels with respect to possible skin reaction from long-term contact. Your opinion will probably be passed on to our respective customers. MBV/WBA:jmm M. B. Ver Nooy * W. B. Ackart ucc 0635^
