Note that, these points are associated with the standard atmospheric pressure. The operating temperature of neoprene foam differs from solid neoprene and is able to handle temperatures up to 200 degrees Fahrenheit. Thanks to polychloroprene, surfers are able to hang 10 in climates that would otherwise be far too forbidding. Amorphous Polymer: T g 1 (C): Poly(chlorotrifluoroethylene) 87: Poly(vinyl chloride), PVC When you increase pressure on ice, it lowers the melting point temperature. neoprene (CR), also called polychloroprene or chloroprene rubber, synthetic rubber produced by the polymerization (or linking together of single molecules into giant, multiple-unit molecules) of chloroprene. data sheet specification description; K). It is produced by many plants and animals (including humans) and its polymers are the main component of natural rubber. When heat degradation occurs, it doesn't manifest in stretching or melting, but it hardens. When working at temperatures below 0 degrees Fahrenheit, however, neoprene stiffens and becomes unusable for most applications by the time it reaches -50 F. Neoprene can withstand temperatures of up to 135 degrees Celcius without degrading. All amorphous polymers follow a temperature response that is similar to that of PC.
