Roosevelt Road Chicago, Illinois Dear Carl: As part of our continuing effort to improve the tensile strength of 6222 gasket, expecially .058 - .066 caliper, we conducted a handsheet study to determine the effect of a small addition of Vanderbilt's Btityl Zimate to current formulation, the intention being to accelerate the heat curing process of the rubber. Our finding is that the addition of 1.5 parts Btityl Zimate to 100 parts rubber produced a sheet with 20-30$ more tensile strength over a standard sheet. This seems especially true during the early stage of heat curing. Simultan eously we observed a slightly greater tendency of the sheet to crack upon flexing compared to a standard one. We are interested in checking this out in actual production run. The text will comprise addition of Bcityl Zimate to 5-6 batches of the next run of .058 .066 caliper 6222. If you agree with us, please give your permission to do so. Very Truly again. ^PD-J 53.0002542 cci C. I. Hayden March 6, 196? tot 9. fTKS&i J. Ia&rSGQ -wit The flexibility was run tqr C.
