A study of the thermal stability of polychlorotrifluoroethylene

It has been shown that articles of simple shape that are fabricated from polychlorotrifluoroethylene are serviceable at 400°F for 6 months if no mechanical strength properties are required. Also, it has been shown that fabricating procedures that do not involve large mechanical forces, such as friction and shear, result in products of better heat resistance than fabricating techniques that do involve large forces. A detailed study of the effect and reduction of such forces should result in improving the high temperature operating characteristics of polychlorotrifluoroethylene. Finally, it has been suggested that the study of the degradation of polychlorotrifluoroethylene is complicated by the presence of more than one degradation mechanism under certain conditions.
