UVT Acrylic Ultraviolet Transmitting Sheet
What is UVT Acrylic Ultraviolet Transmitting Sheet?
UVT Acrylic Ultraviolet Transmitting Sheet has unusual optical clarity, excellent light transmission and outstanding weatherability. It is unaffected by sunlight, resists aging and maintains good stability under variable condition of heat, cold, moisture and other exposure.UVT Acrylic Ultraviolet Transmitting Sheet will not warp, crack, craze or corrode. Because it is more optically perfect and fabricates and machines better,UVT Acrylic Ultraviolet Transmitting Sheet is half the weight of comparable glass, and has good shatter resistance and excellent durability.
Acrylic polymers are among the most light-stable transparent plastics. This is largely due to their exceptionally low absorption of light. They are almost totally transparent to all visible light and to long wavelength ultraviolet light (UV light with wavelength greater than 290 nanometers).
There are two general types of clear acrylic: UVA (ultraviolet absorbing) and UVT (ultraviolet transmitting). 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. It is this characteristic which makes acrylics unstable when subjected to high levels of short wavelength radiation; this type of energy is absorbed by the polymer, and if in large enough quantity, will break down chemical structures causing the plastic to yellow, craze or fog. However this should be a consideration only when the acrylic is exposed to artificial, high-intensity, short wavelength ultraviloet light. Natural sunlight is filtered through the atmospheric layers, so that at sea level there is practically no ultraviolet light below 300 nm. The remaining ultraviolet light (between 300 and 400 nm) is sometimes referred to as UV "A" rays. The "B" and "C" rays are lower than 300 nm and these rays not only break down plaqstic but are also more harmful to human tissue. It is for these reasons that tanning salons most often use UV "A" fluorescent bulbs in their solariums.
