What is UV (Ultraviolet) light ?
Ultraviolet Radiation (UV) mainly comes from the Sun. There are some others man made sources like lamps and tools (welding tools) can produce UV radiation. The Sun is the primary source of UV radiation. UV divide into 4 different categories based on wavelength:
- UVt-Max : Wavelengths (380-400 nm), Ozone layer can not block this wavelengths. Most dangerous for human body and (living and Nonliving) every things. Consequently it causes of skin cancer, skin aging, eye damage. **Normal film can not block UV t-Max. Only UV400 window film can block this wavelengths.
- UVA : Â Wavelengths (315-380 nm) Ozone layer can not block this wavelengths. Most of us expose to large amounts of UVA throughout our lifetime. UVA, which penetrates the skin more deeply than UVB and UVC, it play a major part in skin aging and wrinkling (photoaging).
- UVB :  Wavelengths (280-315 nm) are slightly affecte by ozone levels. Decreases in stratospheric ozone mean that more UVB radiation can reach the earth’s surface, causing sunburns, snow blindness, immune suppression, and a variety of skin problems including skin cancer and premature aging.
- UVC :  Wavelengths (100-280 nm) are very strongly affecte by ozone levels, so that the levels of UVC radiation reaching the earth’s surface are relatively small.
What is UV400?
UV400 is a form of ultraviolet radiation protection associate with Window Tinted Film. UV400 protection considere to provide 100% protection against harmful ultraviolet rays, including UVt-Max, UVA, UVB and UVC. It call UV400, because it blocks all the rays of light up to a wavelength of 400 nanometers. UV400 has a higher level of protection than other all types of window tinted film.
