3M™ High Intensity Prismatic Reflective Sheeting Series 3930 – Blue

3M™ High Intensity Prismatic Reflective Sheeting Series 3930 is a non-metalized microprismatic reflective sign sheeting engineered for durable traffic-control signs, guidance signs, work-zone devices and delineators exposed vertically in service. This blue sheeting is part of 3M's High Intensity Prismatic family and is designed to provide strong nighttime retroreflectivity along with vivid daytime color for professional traffic and safety-sign fabrication.

Key Features & Benefits

• High Intensity Prismatic performance: microprismatic optics return light toward its source to improve nighttime sign visibility.
• ASTM traffic-sign performance: Series 3930 conforms to ASTM D4956 Type III and Type IV performance requirements.
• Pressure-sensitive adhesive: designed for permanent application to properly prepared sign substrates.
• Durable sign construction: intended for long-term outdoor traffic-control and guidance signage.
• Professional imaging options: compatible with approved sign-imaging methods and matched-component systems; confirm the selected ink, film or processing method is qualified for the required finished-sign specification.
• Multiple roll sizes: CrafterNV options include 15", 18", 24", 30", 36", 39" and 48" widths in 10-yard and 50-yard lengths.

Choosing & Using 3M 3930 Sheeting

Choose the color and roll width required by the sign specification, then verify that the substrate, imaging method and any overlay or component films are approved for the intended sign system. Series 3930 is intended for application to properly prepared sign substrates. For regulated traffic-sign work, the finished sign—not only the reflective sheeting—must meet the applicable agency, project and jurisdiction requirements.

The 10-yard options are convenient for lower-volume production and shorter jobs, while 50-yard rolls are better suited to ongoing sign fabrication. Width choice should be based on finished sign dimensions, nesting efficiency and expected waste.

Frequently Asked Questions

Is 3M Series 3930 Engineer Grade reflective?
No. Series 3930 is 3M High Intensity Prismatic sheeting. It provides a higher reflective performance class than standard Engineer Grade sheeting.

What ASTM type is 3M 3930?
3M Series 3930 conforms to the performance requirements of ASTM D4956 Type III and Type IV reflective sheeting.

Can 3M 3930 be used for traffic signs?
Yes. It is designed for durable reflective traffic-control and guidance signs, work-zone devices and delineators. Always follow the governing sign specification and approved component system for regulated applications.

Is this reflective vinyl for vehicle graphics?
Series 3930 is primarily a traffic-sign and roadway-safety sheeting rather than a general vehicle-wrap film. For fleet or vehicle graphics, select a reflective graphic film designed and warranted for that application.

Can I print on Series 3930?
3M supports qualified imaging methods for this product family. Printer, ink, processing and matched-component requirements vary, so verify the complete imaging system before production.
