UV radiation comes primarily from the sun and is made up of UVA, UVB, and UVC rays. UVC rays do not reach Earth, but both UVA and UVB rays pose health risks. Learn more here.
Acrylic. Acrylic is the most notable material used in outdoor applications for UV resistance. Also called PMMA (Polymethyl methacrylate) is a transparent thermoplastic material better known by its chemical name “plexiglass.”. In addition to being UV resistant, acrylic possesses high rigidity, excellent strength, and optical clarity.
Acrylic surfaces can be protected from UV damage by coating them with gloss Krylon UV -resistant acrylic. This finish repels water, prevents fading, and does not yellow. When painted with acrylic, it is vulnerable to dust, yellowing, and UV rays. The contaminants in these paints can cause long-term damage to your cherished artwork.
to fully protect eyes from damaging UV radiation is to block it in the lens. UV AR coatings have no meaningful protective impact between 350 and 400nm, the bandwidth that accounts for 70 percent of total UV exposure at sea level.1 UV AR coatings can be a sensible way to augment UV protection – but only if the majority of rays are blocked by
In the case of certain products, harmful UV rays can speed up the rate of oxidation and degradation and greatly compromise the integrity of products. On the other hand, healthful UV light can act as a natural preservative. This type of UV light can fight microbial growth and keep products fresh even after days, months, or even years in storage.
UV-A rays, with wavelengths 315 to 400 nm, represent 95% of the ultraviolet rays which reach the surface of the earth; UV-B rays, at wavelengths 280-315 nm, is largely blocked by the ozone (O3) layer, but those that cross it are responsible for short-term damage, such as sunburn. UV-C rays, with wavelengths 100 to 280 nm, are the most dangerous
UV. Another urban legend is the ultraviolet rays have negative effects on Plexiglas over long periods of exposure. As mentioned above, Plexiglas is chemically inert and doesn't react at all to sunlight no matter how long it has been exposed (Plexiglas cockpit covers on WWII planes are still clear despite decades of sun exposure).
Clear Acrylic Sheeting. The most common form of acrylic, the flexibility of clear sheeting is evidenced mainly by the staggering variety of dimensions it can be ordered in. Thicknesses range from four inches to a 1/25th of an inch; widths from three feet to ten feet; lengths from four feet to twelve and a half feet.
3. Nuts and seeds. Walnuts, hemp seeds, chia seeds, and flax all contain omega-3 essential fatty acids. Fish and eggs are also great sources of this clean, skin-loving fat. Our bodies can’t make
