MM (SCMJ INTER- OFFICE MEMO M. Friefeld To From 1>. NOOne Flemington At at Carlstadt H-<L. IOM 19-1 April 9, 1973 F. Leotta copy to E. Peretz We are sending you four samples of plasticiser. Two of them are from Stoney-Mueller and we would like to have some check on these materials as they are from a new supplier. if you could clo a G.C. on them and also a refractive index on these and send us the results we would appreciate it. What I want is to have some data which we can refer back to if we do get any problems. The other two samples are from Union Carbide which could possibly be used as a standard.

Antifoam Evaluation Witco submitted an antifoam (BR58-28) which was found to be equal or better to TBP in both the foam retarding and defoam ing characteristics. In addition, a Betz defoamer was tested using one of their homemade antifoam test apparati. The Betz defoamer was found to be unsatisfactory. A test apparatus sim ilar to the one used by Betz will be constructed in Burlington. A report will be issued when the construction of the antifoam tester has been accomplished. b. Sodium Lauryl Sulfate Witco Ultra-Sulfate-1 has been put on the approved supplier's list after satisfactory plant trials. 2. In-Process a. Filter Cloth Evaluation A total of 11 filter cloth types were evaluated via leaf fil tration. Types of cloths tested were multifilament as well as monofilament cloths with plain and satin weave. Amtec sub mitted 4 cloth types for evaluation. All yielded unsatisfactory results. From the 7 cloths tested submitted by Tobier, Ernst and Traber (TET), 2 were found to be of interest. One cloth has been ordered and will be no cost to Tenneco if the cloth will last under 6 weeks. The cloth evaluated presently on drum #1 has completed 6.25 weeks of run time at the time of writing. The productivity remained relatively constant and ranged from 900 - 1,200 lbs/hour (1,100 - 1,500 for normal cloth). It must be noted, however, that part of the productivity is lost (^10 - 20%) because of a faulty doctor blade on #1 fil ter (Process Engineering is investigating a new doctor blade). Excessive downtime on this filter indicates that this cloth type is far superior to our presently used cloth (long downtime causes cloth blinding). Another cloth is presently being evaluated on #3 filter. This cloth is from Goodman Company and is a multi filament satin weave. Productivity is at present from 1,500 to 1,800 lbs/hour. The cloth is about 2 weeks 'old. b. Solids in the Batch Mix tank - "A" Plant A sample of a solid build-up found in the "A" Plant batch mix tank was identified as polystyrene. COLORITE 0X4767 c. TCE in Filter Effluent A filter effluent sample from a 150 resin run was checked for possible TCE contamination. 3. Finished Product a. Dispersion Resin Air Release Specifications Tentative air release specifications have been set for all dispersion resin types save 1716. Due to a wide range of 1716 and limited data available, this resin type was put on a DAR status. Once more data becomes available, a specifica tion will be set. b. Volatiles in RR-501 - Specification Data on hand is not representative of new production schedules. Most of the data available are from runs through the l.OM-lb dryer. The higher volatile levels, however, were experienced in the 40M-lb dryer line. More data is needed to set a realis tic specification. Compound Plant 1. Raw Materials a. Lead Analyses of Stabilizers Analysis capabilities for determination of lead in dibasic lead stearate and tribasic l.ead sulphate have been established. lead assays will be performed on all incoming shipments of these raw materials. b. Plasticizers (1) DIOP DIOP has been Tntroduced to the Compound Plant as a sub stitute for DOP. .Analysis capabilities have been estab lished for this raw material. Infra red and gas chromato graphic analyses of the too DIOP shipments showed only small amounts of impurities (less than found in DOP). # (2) DTDP from Cary-Page A recent sample of DTDP submitted by Cary-Page was iden tified as DTDP with no unusual cross contamination.

Particle Size Control A meeting was held in Burlington to review this Process Engin eering program. The data generated in Flemington and Burlington presented a good characterization of the parameters tested. Based on this, a reduction in test frequencies was agreed upon. An interim report will be issued by Process Engineering. A total of 21 water analyses in VCM, phenol in VCM and water analyses were performed in support of this effort. 2. R&D a. Haze Analyses This program was continued with the characterization of resid ual monomer in 200-2 resin. D. Miscellaneous 1. DTDP and POP from Stoney-Mueller Samples of the above plasticizers were submitted by T. Noone> Carlstadt for evaluation. Along with the samples from Stoney-Mueller two samplesof the same plasticizers from Union Carbide (UC) were submitted as a standard. It was found that the Stoney-Mueller DTDP had a cross contamination level of 0.28% of D0P (the UC DTDP showed <0.1% D0P). The Stoney-Mueller D0P contained 2.02% of DTDP while no DTDP was detected in the UC D0P. * 2. Aix Pollution Seminar The writer attended an air pollution seminar from March 26th to 28th. Topics covered were testing, instrumentation and calculation of emitted pollutants. 3. Personnel. Mr. W. Stewart joined Tenneco on April 2, 1.973 as a chemist in the Analytical Laboratory of Burl irigton' Qua Li ty Control.
