Daily life exposition to different sources of UV Light: while the sun is our primary natural source of UV radiation, artificial light sources may also incur into unique hazardousness, according to its wavelength range of the emitted UV radiation.
The sun emits electromagnetic radiation of different energy according to its wavelengths Ultraviolet (UV) radiation is defined as that portion of the electromagnetic spectrum between X rays and visible light.
Some of the radiation, such as that making up the colours of the rainbow, is visible by humans while the part of radiation beyond the violet end of visible light is called UV radiation and can not be seen by humans eyes.
The UV spectrum is divided into:
• Vacuum UV (40-190 nm);
• Far UV (190-220 nm);vlt
• UVC (220-290 nm);
• UVB (290-320) and
• UVA (320-400 nm)
UV polymer protection depends on customer requirements and final applications properties demand over time
According to the polymer and final article, different types of light barrier requirements are established, to avoid the negative effects of UV radiation.
UV polymer protection is commonly recommended for coex structures where the cap layer is subject to outdoor weathering such as hail, dust, sand. Over the past years and decades of experience, Sukano developed its own database of UV additives, polymers and material thicknesses to tailor your UV masterbatch formula according to specific customer applications and exposure conditions.
Sukano technical experts will assist you to select a product or tailor made one of your choice respecting all requirements of your final application.
