From these results it will be seen that although this XM1000 material is certainly superior to ordinary Bakelite from the point of view of susceptibility to tracking, it is only so conditionally. When the heat energy or incendivity of the H.T. discharge is increased sufficiently it is just as liable to breakdown as ordinary Bakelite. For Battery ignition use it would appear to be better than our std Bakelite. We suggest a real service test of materials of this kind is whether they can be moulded and run satisfactorily as a wipe type magneto distributor. All synthetic resin mouldings can be used satisfactorily when the heat energy of the H.T. discharge is sufficiently low. H E West. | ||
