Introduction
ASTM D4956 Type XI Reflective Sheeting is the highest-grade microprismatic reflective material used for critical traffic control applications. Designed to meet stringent safety standards, this sheeting provides exceptional retroreflectivity, ensuring clear visibility in low-light and nighttime conditions. It is widely used in highway signage, work zones, and urban traffic control systems, where enhanced reflectivity and long-lasting durability are essential.
Key Features of ASTM D4956 Type XI Reflective Sheeting
1. Advanced Microprismatic Technology
Type XI sheeting is manufactured using microprismatic retroreflective elements, which efficiently return light to its source. This high-intensity reflectivity ensures visibility from long distances and at multiple entrance angles, improving driver reaction times.
2. Meets ASTM D4956 Type XI Standard
This sheeting complies with the American Society for Testing and Materials (ASTM) D4956 Type XI standard, which sets rigorous requirements for retroreflectivity, durability, and color performance. It is specifically designed for use in high-speed roadways and areas requiring maximum visibility.
3. Superior Nighttime Visibility
Compared to lower-grade reflective sheeting (e.g., Type I or Type III), Type XI offers up to ten times higher reflectivity, making it the preferred choice for critical regulatory and guide signs, overhead freeway signage, and emergency applications.
4. Long-Term Durability
Weather-Resistant: Resistant to UV radiation, extreme temperatures, and humidity.
Impact and Chemical Resistance: Designed to withstand scratches, abrasions, and chemical exposure.
10+ Years Outdoor Performance: Ensures long-lasting reflectivity with minimal maintenance.
5. Easy Application & Compatibility
Pressure-Sensitive Adhesive: Facilitates secure bonding to substrates such as aluminum, steel, and rigid plastics.
Compatible with Digital Printing & Screen Printing: Allows for custom sign production.
