What are the differences between various grades of black fiberglass tissues?

The differences between various grades of black fiberglass tissues primarily lie in their fiber diameter, weight per unit area, tensile strength, and chemical resistance. Lower grades typically have coarser fibers and lower tensile strength, suitable for general applications like insulation. Higher grades feature finer fibers, higher tensile strength, and better chemical resistance, making them ideal for more demanding applications such as high-temperature environments or chemically aggressive settings. Each grade's specific properties determine its suitability for particular industrial uses.
