Electrical and physical properties of IN-420: A new chlorinated liquid dielectric

A family of new chlorinated liquid dielectrics has been developed. One member of this series, dichloro-1,3,3-trimethyl-1-phenylindan (designated as IN-420), appears particularly suitable for use as a capacitor impregnant. Values of dissipation factor and d-c resistivity are comparable to or somewhat better than existing commercial chlorinated biphenyls. Its dielectric constant and dielectric strength are somewhat superior to those of the chlorinated biphenyls.
