Computation of Revan Topological Indices for Phenol-Formaldehyde Resin
Phenol-formaldehyde resin has a wide range of moldings.The phenolic resin retains properties at the freezing point; hence, it is difficult to determine its age.However, it has immense consumption in manufacturing electrical equipment due to abc material its insulating property.There are many types of topological indices such as degree-based topolog
