Nippon Sheet Glass Co., Ltd. (NSG) has developed a new range of UV-cut automotive glass products calledUV Protect 400TM. UV Protect 400TM blocks 99% (*1) of UV rays (300nm-400nm), which includes the longer wavelength UVA (315nm-400nm) that can cause damage to deeper layers of human skin.

The new technology can be used in all car windows and is the world's first automotive glass that blocks the UV radiation of up to 400nm wavelength by 99%.

Current automotive glass products that can block 99% (*2) of sub-380nm UV ray transmittance are already available and becoming one of the standard features for light vehicles sold in Japan. The NSG Group, however, has focused on effectively blocking the longest-wavelength range of UV (380nm-400nm), which can penetrate into deeper layers of the skin.
