Polylock is interlocking helically wound strip. When a bend is applied to the polylock it loosens the lock between the joints which can make the polylock less air tight. This is acceptable in external conditions but should ideally be wrapped with a heat wrap to make sure all of the exhaust gases are kept inside.
