Photosynthetically active radiation (PAR) light transmission varies with the type of film additives. Typical PAR values are: ultraviolet-stabilized film, 88-91 percent, infrared/anti-condensate film, 82-87 percent, infrared/anti-condensate with diffusion, 77-88 percent. Dust, smog and plastic deterioration can also reduce light transmission.
Taking measures to block UV rays from passing through your windows can go a long way to protect your property and your health. Here are two strategies you can use to block UV rays: Deflection; Deflection is a strategy that involves diverting the UV rays from the surface of the glass or window to the atmosphere.
(nm) and 400 nm. UV radiation is invisible to naked eye and are broken down into three main bands (UV-A, UV-B, and UV-C). The main source of UV exposure is from the sun, but it is typically limited to the UV-A band, as the earth atmosphere protects us from the harmful UV-B and UV-C rays. Nonetheless, UV
UV protection for packaged foods. Transparent plastic packaging is increasingly replacing traditional food packaging made of glass and metal. The advantages of transparent plastic packaging are; its low weight, low cost, design flexibility and the opportunity to present products in an attractive way. However, compared to traditional packaging
UV Absorbers and Stabilizers. The UV plastic greenhouse films contain chemical compounds that absorb UV radiation. And this prevents it from being transmitted through the film and into the greenhouse. The UV absorbers are mixed in the film’s polymer with UV-stabilizing chemicals.
Forcefield - Uv Sunblock Fabric Protector - Prevent Uv Ray Damage - 22oz. PROTECTION - Protects fabrics, fibers and colored surfaces from the fading and damage caused by the Sun's rays. ABSORB - Absorbs the Sun's energy of UV radiation, and then releases it in a harmless form. SAFE - Safe to use on all types of materials including synthetics
The UV absorber is a type of UV stabilizer that works by absorbing UV light. UV absorbers are chemicals that are added to materials to absorb ultraviolet (UV) radiation and prevent it from damaging the material. This can help prevent the material from fading, discoloring, or breaking down due to exposure to sunlight.
Solar control window film only blocks UV rays – not the red and blue rays that your plants need to grow and flower. And some plants will actually do better with window tints and films, such as those that require less light — which typically have dark green leaves.
The best way to block UV rays is by doing a combination of all of these things. Can UV-C pass through clear plastic? Most acrylic plastics will allow light of wavelength greater than 375 nm to pass through the material, but they will not allow UV-C wavelengths (100–290 nm) to pass through .
