Finished Product Bound Acetate Gel Count - Brabendcr Extruder PHR in Plastisol Paste Total from Section II 75 66 3 146 TOTAL SPECIAL TESTING A. Resin Plant 1. Raw Material l a. Nalco 40-B-03 Antifoam In search for an effective FDA approved antifoam, this Nalco antifoam was tested and found to be unsatisfactory for the use in place of TBP. b. DHW-80 Bottle date and reaction times in the plant were compared again for the various DHW-80 shipments received during the summer months. It was found that while the bottle data is somewhat noisy, reaction kinetics can be predicted from this data. A way of reducing the analysis return time must be found, however, in support of production to predict kinetic behavior of a new DHW-80 shipment. c. Tributyl Phosphate (TBP) A sample of TBP from Commercial Solvents was submitted for alternate raw material supplier evaluation. All properties tested were found to be well within the specification range. In addition, an antifoam evaluation test was run, the results of which compared favorably with TBP test results presently used in the plant. d. Tridecanol The high volatile levels found in 1738 and 1742 type resins during recent production was suspected to be due to changed quality of tridecanol. Gas chromatographic, infrared and Karl Fischer analyses showed no great differences in the impurity levels found in the tridecanol samples analyzed. Further in vestigation led to the conclusion that irregularities in the tridecanol additions during the bagging process is the reason for the high volatile levels. e. Lupersol 223M One lot of the most recent shipment from Luc idol (MMCK052, 10/19/72) was found to be low out of the specification (39.5% COLORITE 014034 spec 40.0%). Purchasing was contacted and a Corrective Action Request issued. 2. In-Process a. Haze and Gloss To further gather data for establishment of a specification range of the optical properties for all Plastisol rosins, for ty-two haze and gloss evaluations were performed. b. Slop in 0565 (Process Engineering Support) A residual vinyl tacetate analysis was performed on a freshly stripped sample of latex to help to define the reason for slop encountered during 0565 runs. While no background data of this nature is available, future 0565 runs will be moni tored for its residual monomer content when requested by Pro cess Engineering. Compound Plant 1. Raw Materials a. Plasticizer Shipments A total of seventeen plasticizer samples were analyzed via gas chromatograph and pH meter. b. Bisphenol A in Plasticizers Analysis capabilities have been established for the determin ation of bisphenol A levels in plasticizers (TIOTM). Incom ing TIOTM shipments will be monitored using this method, A method for bisphenol A analysis from Piscataway was received and will be evaluated, c. Tribasic Lead Sulfate (Tribase) This raw material was evaluated as the possible source of the plate-out problem encountered in the 3805-D compound for All Disc. Initial infrared analysis showed no differences in any of the tribase lots tested. A tribase dispersion test was de veloped which indicates the degree of the dispersion of the tri base in a pressed out 3805-D dry blend formulation with an ex cess of tribase added. A memo covering the work done in Burl ington will issue this month. d. Identification of Unknown Compound Plant Inventory A total of twenty drum samples were submitted by Compound Qual ity Control for inventory identification. With the exception of one, akL samples submitted were identified. 2. In-Process a. Color Matching Starting with this report, color matches will be reported by COLORITE 014035 Page 4 Compound Plant Quality Control only. The XI 10 Color Dif ference Meter was received on 9/20/72. C. Flemington Support 1. Haze and Light Transmission Measurements on Impact Modified Plaques Eleven samples of rigid plaques compounded, using experimental im pact modifiers from Piscataway, were evaluated for haze and light transmission values. The experimental modifiers showed better haze and light transmission values when compared with commercial controls. D. Miscellaneous ---------------------- ------------------------------- \ 1.
