What is the water absorption rate of black fiberglass tissue?

The water absorption rate of black fiberglass tissue is typically very low, as fiberglass is a material known for its resistance to water and moisture. It is designed to repel water and not absorb it, making it an excellent choice for applications where water resistance is important. The exact rate can vary depending on the specific manufacturing process and the presence of any treatments or coatings applied to the fiberglass. However, in general, fiberglass is considered to have a negligible water absorption rate, often less than 1%.
