To accomplish this, UV absorbers are added to the liquid acrylic before it is extruded or cast. Some of the energy absorbed by a UV blocking sheet of acrylic will cause the UV absorber to break down into products that will no longer absorb UV light, and this might be a cause for concern in regard to long term effective UV blocking. Any kind of display case can keep your items safe from the usual risks like dust, grime, dampness, fingerprints, spills, and more. But specialty UV cases are manufactured with UV protectant additives. This industry-standard additive helps block UV rays from hitting the product. This is the strategy most museums take to keep their priceless stabilizers, it will degrade under intense and prolonged UV light exposure. Therefore, it is not suitable for use in sun tanning beds. ACRYLITE® OP-2 (ultraviolet filtering) acrylic sheet is a cell cast sheet product that absorbs approximately 98% of the incident UV light. It is used in museums to protect historical Here are our top tips for preventing colour fading without completely blocking out the sun. Voile or Net Curtains: a sheer fabric like voile or net can help to diffuse direct sunlight. Although you won’t block out UV rays, diffusing the light can stop the intense and direct glare that tends to lead to colour fading in fabrics and wood. UVA has additives incorporated within the polymer which block out most ultraviolet light. UVT has no ultraviolet filtering chemicals, therefore it transmits ultraviolet light as low as 290 nm. What is UVT Acrylic material? Due to their chemical structure acrylics absorb, and as a result are opaque to UV light below 290 nm. While glass windows alone only block 40 percent of harmful UV rays, some window films can block up to 99.9 percent. Solar films also regulate indoor temperatures, so rooms stay cooler in summer The chemical composition of plastic materials affects UV-C penetration. Acrylic plastics will permit rays with a wavelength of 375 nm to pass through, but will block UV-C wavelengths of 100 to 290 nm. These short wavelengths can’t travel very far through air, so they are converted into ozone, which is a toxic gas. UV Transmitting Acrylic. 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 .
