Mr. J. H. Thomas, Toledo R. F. Shannon, Granville KAYLO PRODUCT DEVELOPMENT
October 23. 1967 Mr. R. J. McEvoy, Granville
PI Pfeifer sent me word last week you wanted to talk about the 'replacement of asbestos* program. I attempted to contact you several times last week, plus on Monday of this week, without success. As you know, I was in Berlin all of last week working on in-plant process problems.
To follow-up on your request to move promptly on the evaluation of opoxy coated Flberglas yarns, Pi Pfeifer asked Bob Wong for help in getting for us a supply of such yams for our evaluation in Kaylo. As soon as the Chemistry Lab produces the yams for us, we will evaluate in Kaylo and
send you the results.
The opoxy coated yams reported recently as being used to good advantage in cement are in reality 12 end rovings coated with epoxy resin to form miniature 'fishing' rods. They are quite stiff, about the size of tooth picks and about 1-1/2 to 3 inches long. Mr. MoEvoy agreed to my accompany ing Mr. Potts, of FIM Division in New York, to Rensselaer Polytechnic Institute on Wednesday, October 25, to discuss the concept with Professor Klink, the inventor.
The program directed toward replacing asbestos in Kaylo is complicated by (l) the huge investment we have in the SID cylinder pan pouring process at Berlin, (2; the need for additional plant capacity and (3) problems which must be answered as to type of process to use in the new facile" before expansion is undertaken. Questions to be answered include: we expand Berlin (901 now in Toledo) or do we build a new plant and (2) if we build a new plant, do we install the SID cylinder pan pouring process or another process yet to be determined?
I cannot say at the moment with any assuranoe we will be successful in developing another type of reinforcement, preferably glass, which can be adapted to the SID cylinder pan pouring process. The best odds I can project at the moment are 50/50. In any case, the problem won't be solved in a week or month. In fact, we will be lucky to carry the program to a plant trial stage after a year's effort.
In view of the fact the probability of finding another reinforcement,
which can be used in our present process, is at the best 50/50, do we
also direct some of our effort toward a new process and if so, what
process? At the moment there are no high temperature insulations on the
market which do not contain at least some asbestos. To the best of our
knowledge, the only asbestos free product on the market in recent years
was OCF's Multitemp. Do we attempt to improve Multitemp? My answer would
be no. The Multitemp concept of post impregnating a prebonded nroduot
wasiill conceived

Instud, if tha decision ia to develop a produot baaad on glass fibers, I would recommend wa work on an lnorgania bonded glass fiber composite, which can be produced In a one-step operation, possibly via a modified version of the filter press process.
We must not forget the bonded aggregate type produot. Careytemp is a bonded perlite reinforced with glass and asbestos fibers. If Philip Carey could solve their breakage problem, Careytemp would become the best high temperature product on the market. I believe an OCF version of such a produot containing 100 percent glass reinforcement would have a high prob ability of success. As you. know, this is the program which Marketing oanceled on us year after year in the past.
Now that I have given you a brief insight as to my thoughts as to where we go from here, I would like to suggest for your consideration the follow ing program. Initiate a hard hitting intensive search for a fiber substitute for asbestos. The effort should be directed mainly toward glass fibers. We should not, however, close our eyes to other ceramic fibers, which become commercially available in the meantime. We should also Initiate an exploratory program directed toward ahecking the feasibility of develops ing a glass reinforced bonded aggregate or an inorganic bonded high temperature glass fiber product (Multitemp via a different process).
Tour first thoughts to the above may be we are spreading our activity too much. We should Instead deolde on one program. Under ordinary circumstances I would agree with the idea of concentrating on one approach. However, we must recognize the fact that if we direct all our efforts toward finding a substitute for asbestos and if not successful, we could find ourselves with two plants (Berlin and the new one to be built) equipped with s process requiring asbestos. On the other hand, if the decision is not to continue looking for s substitute for asbestos, but start to develop s bonded aggregate or high temperature glass fiber (s la Multitemp) product, we are giving a death sentence to Berlin, the SID cylinder process and the huge invest ment in the pan pouring process. A.so, we will fsoe an outlay of 6 to 10 million just to revamp Berlin to the new proeess.
What are the chances of technical success? I would guesstimate 50/50 of replacing asbestos in the pan pouring process, 90 percent for a glass reinforced bonded aggregate produot and about 80 peroent for a one-step process Multitemp type produot having a 30+ percent gross margin.
What really bothers me is timing. To carry out any type of program we will need manpower and facilities. At the moment I am down to two technicians and about 1/2 the space allocated to Ksylo prior to 1964, when all research on Kaylo was terminated at Granville. Two of our three available autoclaves are in storage for lack of spaoe.

At the moment we are attesting to zero in on the improved stress corrosion formulations to be poured after November 15 when a supply of 2399 glass becomes available and provide as much technical service to Berlin as time and manpower will permit. Our manpower situation is becoming critical. The recruiting program for new people is batting zero. As for additional space, we are working with Fred Swank and Ike Mjyers. A 901 will probably be required to provide the space we need.
If you have the time availatie Thursday when you come to Granville, I would like to have the opportunity of discussing this program with you.
