Advantage:
1. excellent electrical insulation made it quite desirable as casing for the growing electrical industry
2. for making patterned molds, which enabled increased production.
3. The ingredients to make the resin (carbolic acid and formaldehyde) were easily obtainable and available in large amounts.
