Physical Properties of Vacuum De-Oiled DC-325 Ablative Material.
MCDONNELL CO ST LOUIS MO
Pagination or Media Count:
The purpose of the test was to determine the effects of vacuum de-oiling on the physical properties of DC-325 silicone elastomeric ablative material. Thermal conductivity, Shore A Hardness, size, weight, tensile strength, and elongation were the physical properties measured before and after the vacuum exposure. All physical properties showed appreciable change except thermal conductivity however, the weight and dimensional changes were slight. Author
