Cold tolerance and mechanical properties of thermoplastic polymer based composite for the marine cables operating in polar regions

Cold tolerance of a thermoplastic polymer largely depends on the type and content of about 20 or more additives used to make the polymer. Observing the change of dynamic viscoelasticity as a function of the temperature change through glass transition temperature measurement is a representative method for evaluating cold resistance. In this study, mechanical properties of composite materials prepared by mixing various types of thermoplastic polymers and various additive components were evaluated to improve their cold tolerance performances. The cold tolerance was improved by blending resin having an embrittlement temperature lower than the operating temperature.
