a Phosphorescent Fire Retardant Material for Garments and Accessories
Join the Safety Revolution
ESA B3017-NT is a phosphorescent fire retardant trim that can be used with ESA reflective tapes or on their own to introduce a new safety element to garments and accessories. ESA NT uses phosphorescent technology that absorbs UV light from natural or artificial light which is then emitted as an “afterglow” in low or no light conditions.
Ideal for increasing visibility of personnel involved in work duties such as,
Fire Fighting
Search & Rescue
Police Operations
Offshore Drilling
Oil, Electrical & Gas
Utilities
Hot Work Processes
Welding
Military
Easily identify operational staff in the dark and low levels of light, works well in low levels of smoke.
B3017-NT is a 100% cotton substrate with a Proban treatment making the materials suitable for use in the production of fire retardant garments and accessories that are required to meet the international standards listed below. B3017-NT can be laundered up to 50 times in a domestic machine at 40℃ without affecting FR or Glow performance.

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.
