MATERIAL - ELASTOMERS - TEFLON, NEOPRENE, TA-77 SYNTHETIC RUBBER (T. A. MANUFACTURING CORP.). AROMATIC FUEL AND WEATHERING RESISTANCE
Abstract
Suitable specimens of general purpose neoprene AMS 3209; aromatic fuel resistant neoprene AMS 3215; TA-77 synthetic rubber and teflon were subjected to various environmental tests. Atlas Type XW Weatherometer exposure for 250 hours and ozone exposures (ASTM Method 1149-55T) resulted in no cracking in the teflon and general purpose neoprene AMS 3209, but the T. A. synthetic rubber and aromatic fuel resistant neoprene AMS 3215 cracked. Heating at 212 F for 70 hours did not appreciably harden any of the four materials. Twenty-four hours immersion in JP4 fuel caused only very slight swelling of teflon, but the two neoprene materials and the TA-77 synthetic rubber swelled considerably as a result of immersion.
