Join the Safety Revolution

ESA NT is a patent pending combination of reflectivity and phosphorescent technology which has been developed to improve the visibility of the wearer in all light conditions. Standard retro-reflective tape only works with a light source usually vehicle headlights. ESA NT uses phosphorescent technology that absorbs UV light from natural or artificial light which it emits as an “afterglow” in low light or no light conditions.

ESA is a trusted brand of retro-reflective material, that meets and exceed ANSI 107-2010 and EN ISO 20471:2013 for high visibility warning clothing. By combining retro-reflective and phosphorescent technologies ESA NT improves safety in all light conditions.

How ESA NT works

The phosphorescent element in ESA NT contains Strontium Nitrate based pigment and other chemicals formulated to meet our exact specifications for maximum glow intensity, extended decay time and laundry performance.

The formulated pigments have a high capacity for absorbing and storing light energy. The atoms in the pigments absorb photon energy from an ultra violet light source. The light source can be natural daylight or artificial UV light such as fluorescent strip lights. These electrons act like a battery effectively storing light energy.

This energy is then emitted as light, once there is no more light to absorb. The light that is given out is called an afterglow. The chart below gives charging times to achieve a full 8 hours of however ESA NT will absorb light from the surrounding environment in less than one minute.

The afterglow can be seen in reduced light conditions such as, a dimly lit warehouse; in the shadow of large machinery; inside abandoned buildings, underneath large aircraft; on an unlit road at dusk; low level smoke.

The afterglow can be seen in complete dark conditions such as, unlit roads, railway tracks, tunnels, nighttime work away from spot lights.
