About this series
The 3500 / 3800 / 3900 Series is our photoluminescent PVC vinyl: a film whose pigment layer absorbs ambient or artificial light and releases it as an afterglow when the lights go out — the material behind emergency egress marking, safety signage and glow decoration.
The three codes are three constructions. 3500 is the 120 µm light-green base grade; 3800 offers green films at 150 µm and a heavy 270 µm build; 3900 is a 220 µm light-green construction. Thicker builds carry more pigment layer, which is what buyers stepping up the range are paying for.
All grades share the same working format: 1.24 m (49 in) × 45 m rolls with a white permanent adhesive on premium release paper, cut-friendly for signage legends, striping and shapes.
Key features
- True photoluminescent pigment layer: charges under daylight or room lighting, then releases a visible afterglow in darkness.
- Three constructions — 120 µm, 150 µm, 220 µm and a heavy 270 µm build — so the glow performance can be matched to the job.
- Wide 1.24 m × 45 m roll: efficient nesting for sign blanks, stripes and large egress markings.
- White permanent adhesive keeps the glow layer bright on any substrate color.
- Cuts on standard plotters for legends, arrows, striping and decorative shapes.
Applications
Emergency and egress marking
Escape-route striping, door frames, handrail and stair-edge marking that stays visible in a blackout.
Safety signage
Exit signs, fire-equipment location markers and instruction plates.
Traffic and vehicle marking
Low-light visibility accents where powered lighting is not available.
Decoration and novelty
Glow stars, wall shapes, event and entertainment graphics.
Technical notes
- Roll format: 1.24 m (49 in) × 45 m; MOQ 1 roll.
- Film: photoluminescent PVC — 3500 at 120 µm, 3800 at 150 µm and 270 µm, 3900 at 220 µm.
- Adhesive: permanent, white.
- Liner: premium release paper.
- Glow duration and brightness depend on the charging light and the grade — brighter, longer charging gives a stronger afterglow.
- For code-regulated egress systems, confirm the luminance class your market requires before specifying a grade.
Common questions
How does the glow work?
The pigment layer stores energy while it is exposed to daylight or room lighting, and releases it as a green afterglow when the light goes out. The cycle repeats indefinitely — no power, wiring or maintenance.
What is the difference between the three series codes?
Construction thickness. 3500 is the 120 µm base grade; 3800 runs 150 µm and a heavy 270 µm build; 3900 is 220 µm. More build means more pigment layer, which supports a stronger, longer afterglow.
How long does it glow?
It depends on the grade and how it was charged — stronger and longer light exposure stores more energy. As a working rule the glow is brightest in the first minutes after darkness and fades gradually, which is exactly the window egress marking is designed for.
Can it be used for regulated escape-route systems?
Photoluminescent egress marking is often governed by luminance standards that differ by market. Tell us the class you need to meet and we will confirm which grade fits before you commit.
