In addition to the evaluation of TBEP as an antifoam during the previous report period, tris octyl phosphate (TOF) was evaluated for Process Engin eering as a possible antifoam to be used in Burl ington. Tests run with latex as well as with a 1$ sodium lauryl sulfate solution in water yielded poorer antifoam and defoamer qualities for TOF when compared with TBP. b. Lucidol 223M A shipment of the subject raw material (shipment date 4/20/72) showed erratic assay analysis results (e.g. lot MMGC 015 assay 39-^ to 41.3$). Lucidol was contacted via Purchasing and informed about our findings. Through a call from Lucisol (G. Kuzma), we were informed that the erratic assays were traced to a possible operator error during the mixing of the initiator at the Lucidol Plant. In addition to the above lot, one additional lot (MMGC 06l) had a low assay level when analyzed in Burlington (39-8* spec range 40.0-42.0$). 2. In-Process a. In-Process Magftet 'The first stage of the attempt to correlate the In line 4" double tapered step magnet with the syntron laboratory ferro magnetic contamination test on a 24-hour basis yielded unsatisfactory results. It was Sfound that the calculated weights of the labora tory test results were considerably higher when com pared with the weight of iron contamination recovered from the in-process magnet (average 4330 gm x 10-9 vs. 71 gm 10 X"9 per pound of resin respectively). An attempt will be made to monitor the contamination on a lot-to-lot basis. COLORITE 014554 b. 150 Shoe Heel Compound An attempt to compare gel extrusions of a flexible .formulation made from the subject resin with a milled sheet gel test run in Flemington failed. This was mainly due to low stock temperatures dur ing the extrusion, which resulted in a ribbon not suitable for a gel count. The test will be repeated following the next 150 lot. * c. Monitoring of Total and Dissolved Solids in 521, 501 and 250-3 Qentrifuge Effluent In support of the Process Engineering efficiency study of the above resin types, it was found that the 250-3 resin effluent had a total solids content of 0.15$ while BR-521 and HR-501 had a total solids le vel of 0.6 and 1.2$ respectively. The results are close to the anticipated values. d. Haze and Gloss Evaluations (Technical Memorandum) The recently-received Gardner Haze and Gloss Meters were set up and after an initial check-out of the instruments, seven dispersion resin types, as well . as an additive resin and one competetive resin, were evaluated. With the exception of 1738, 1755 and 0565* haze values compared favorably with EXON 640 (<) Gloss values were found to be better than 50% at the 20 angle with the exception of the 1752, 1738 and 1755 resins, which again compared well with the gloss value of the EXON 640 resin of 44$. Compound Plant 1. Raw Materials a. Plasticizer Shipments A total of eight plasticizer samples were evaluated by gas chromatographic and pH analyses. b. Color Matching (1) Small Mill The small mill for color matching was received in Burlington and became operable on 5/16/72. The mill is exclusively used for color match milling. (2) Updating Standard Product Color Formulations The following is a list of color matches per formed on standard product color formulations: 2906-1 Natural 01 2300 Natural T-733 White 245 X606 Gray 151 2602-1 Gray 150 re-match 2022 Gray 148 re-match American Wire Production Brand Rex Kessler Products Olin Conductors Production COIiORXTE 014555 Page 4 In addition, a formulation change was required due to a change in plasticizer for 2022 Gray 148. Color matches are also performed for the Channel Black replacement. c. Color Seminar R.J. Eckman attended a Color-Technology Seminar sponsored by the Diano Corporation. This one-day' course was designed to give an introduction to the color theory. In addition, evaluation of color differences and the matching of colors were covered C. Miscellaneous 1.
