The project is concerned with toxicological evaluation of PVC and, more specifically, the commonly used plasticizer, di-(2-ethylhexyl) phthalate (DEHP). Studies have been undertaken relative to the short and long term toxicologic potential of DEHP. (Author, modified).

Development of Material Specifications and Qualifications of Polymeric Materials for the JPL Spacecraft Materials Guidebook. II. RTV Silicone Adhesives and Potting Compounds,

01 JUL 1965

Authors: J. A. Black ; D. J. Lyman ; D. B. Parkinson; STANFORD RESEARCH INST MENLO PARK CALIF

Five RTV silicone potting compounds and four RTV silicone adhesive/sealants were selected for study under simulated space conditions. Outgassing characteristics of these materials were determined at 150 degrees C and 5x 10 - 6 mm Hg. Outgassed condensable materials are analyzed by infrared spectroscopy: and any visual changes such as sample darkening and softening were noted. Under these conditions, each RTV silicone material evolved large amounts of condensable oil, although ...

Development of Material Specifications and Qualifications of Polymeric Materials for the JPL Spacecraft Materials Guidebook 1. Epoxide Adhesives,

Authors: J. A. Black ; D. J. Lyman ; D. B. Parkinson; STANFORD RESEARCH INST MENLO PARK CALIF

Nine Shell Epon adhesives were selected for study under simulates space conditions. Outgassing characteristics of these materials were determined at 150 degrees and 200 degrees C at 10-6 mm Hg. Outgassed materials were analyzed by infrared and mass spectroscopy, and visual changes such as ample darkening and softening were noted. In thermal vacuum tests of these adhesives little change was observed at 150 degrees C, but at 200 degrees C ...
