Black and white fiberglass tissue are both made from glass fibers, but they differ in color and certain properties. Black fiberglass tissue typically contains carbon black, which provides UV protection and can improve the material's resistance to weathering. It is often used in applications where durability and resistance to sunlight are important, such as in the construction of boats and outdoor structures. White fiberglass tissue, on the other hand, does not contain carbon black and is generally used in applications where aesthetics are a priority, such as in the automotive and aerospace industries. It is also used in situations where the absence of color is beneficial, such as in the production of translucent composites.
