What is the difference between black fiberglass and white fiberglass?

Black fiberglass and white fiberglass primarily differ in their color, which is due to the pigments added during the manufacturing process. Black fiberglass often contains carbon black, which can provide better UV resistance and may be more resistant to yellowing over time. White fiberglass, on the other hand, is typically used for applications where visibility or aesthetics are important, such as in boat hulls or certain types of insulation. Functionally, both types have similar strength and durability, but the choice between black and white often comes down to specific application needs or personal preference.
