Hydraid biosand filters are constructed from medical grade plastic with ultraviolet resistance.
2.
Black became the standard industry color for vinyl standard tape, primarily because of its ultraviolet resistance.
3.
Pigment-based aqueous inks are typically more costly but provide much better long-term durability and ultraviolet resistance.
4.
