. Monsanto FROM (NAME A LOCATION} - Jan Smoke - New York Office OATE : January 28, 1969 subject Plasticizer Evaluation Program reference: = Thiokol Chemical Co. Trenton, New Jersey TO . : - Cumming Paton St. Louis . CC: E. H. Fording - N. Y. Cumming, Dan Smith requests that we do some laboratory work on plasticizers we feel have potential in polysulfide formulation. The laboratory work should be similar to that reported in the write-up presented to Thiokol in October, 1967 with the following changes:* PHR. FORMULATION Thiokol LP-32* CaC03* Plasticizer Sulfur* 100 / 30 ( 25 y . 0.1 ) , 100 Cataivst System Lead Dioxide Stearic Acid Plasticizer I 50 i j The following tests should be made:, 15 1. Miscibility of plasticizer in LP-32 at levels of 15%, 30% and j>02[__plasticizer (Shake test with adequate settling period) 2. Tensile, elongation, and modulus on cured samples. 3.. Volatility tests at 86C and 70C. Rather than charcoal volatility, test should be conducted according to attached Thiokol standard test. 1 4. Instead of water sensitivity, check physical properties after 3 and 7 days immersion in 120F water. 5. Loop compatibility, U.V. and heat stability.
