inter office memo TENNECO CHEMICALS, INC. To W.C. Champion at Burlington from f.W. Kanzler at Burlington subject Supercryl 100 and 100H Testing date February 19, 1974 3PY T</Pile Copy ti be e M Tc Attached is a summary of the test results of all the Supercryl samples submitted to date. Based on the limited data on hand, it appears that the Mill Efficiency is somewhat related to the Haze values. A regression analysis will be made once sufficient data is available. No consistent trend is presently noted in the L,a,b scale readings when compared with the other parameters tested for. It is planned to establish specifications for all three tests performed in Burlington. To help in the interpretation of the L,a,b scale, a diagram of the color coordinates is attached for transmittal to Messrs. J. Wilcox and J. Mahon at the Fords Plant. Attachments (3). FWK/jst F.W.
