automotive distributor cap material of the 1960s
(OP)
Was there a "standard" material for the black distributor caps on US cars of the 1960s? I think I remember Echlin/Accel saying their tan colored high performance caps were of some Alkyd material, as if that was different and "better" than OEM.
And second, probably regardless of the material, was carbon black or something similar used to make the black color?
thanks,

As far as the colorant for the a partiular moulding compound I think they would use inorganic pigments though some carbon black or bone char maybe added to lower the price. Something is conductive as you know, the caps are good at arc tracking.
From a catalogue:
"Manufactured From Innovative, Space Age Plastic, Combines The High Dielectric Strength Required For Today's High-Energy Ignition Systems With Highly Impact-Resistant Qualities Thus Preventing Damage."

Some lighter coloured high performance caps where made of alkyde resins and in the mid 70s Glass Fibre reinforced PBT was also introduced to reduce manufacturing costs and impact strength.
