Abstract : A literature study revealed a new curing system for Neoprene which enables high elongation without high-temperature cures. Thiocarbanilide was evaluated as an accelerator to provide room temperature cores. One compound in a series of compounds had an elongation of 820% at -40 CAND 1200% at room temperature. A second compound had high modulus associated with elongation at room temperature and -40 C. Flights were conducted with 2500-gram balloons. These averaged about 130,000 ft and were extremely consistent in performance.
