In most applications using acrylic sheeting, manufacturers generally favor UV filtering acrylic for its ability to block out harmful UV rays; however, UV transmitting acrylic is also available for applications requiring UV-A and UV-B light. UV-A light (320-400 nm) and UV-B light (280-320 nm) are used in many applications, from medical treatment to suntanning. UV transmitting acrylic sheet is transparent to UV light and provides the superior quality and clarity needed in these applications.
