Enhancing Road Safety: The Role of PVC Reflective Film in Traffic Signs and Markings

1. Reflective performance parameters (key safety indicators)
Luminance (cd/lx/m²)
Engineering grade (Type I/II): ≥50 cd/lx/m² (applicable to general roads)
High-strength grade (Type III): ≥250 cd/lx/m² (highways, complex environments)
Diamond grade (Type IV/V): ≥400 cd/lx/m² (highest visibility, such as bad weather)
Retroreflectivity (RA)
Measures the ability of a material to reflect light back to the light source (unit: cd/lx/m²), as required by ASTM D4956.

2. Durability and environmental adaptability
Weather resistance
Ultraviolet (UV) life: 5~10 years (accelerated aging test standard: ASTM G154).
Operating temperature range: -30°C to +70°C (for extreme climates).

Chemical resistance
Resistant to acid rain and salt spray (conforms to ISO 9227 salt spray test).

3. Physical performance parameters
Substrate thickness: usually 50~250 microns (μm), affecting flexibility and impact resistance.
Tensile strength: ≥20 MPa (to prevent tearing during installation or wind load).

Adhesive type
Pressure sensitive adhesive (PSA) initial adhesion: ≥10 N/25mm (to ensure firm adhesion).

4. Optical design parameters
Wide-angle reflection performance
Entrance angle and observation angle are optimized to ensure visibility from different viewing angles for the driver (e.g. 0.2°~2° observation angle).

Color and chromaticity
Conforms to CIE 1931 chromaticity standards (e.g. red, yellow, and white must meet traffic sign color specifications).

5. Certification and standards
International standards:
USA: ASTM D4956 (Traffic Reflective Film Classification), MUTCD (Manual of Uniform Traffic Control Devices).
Europe: EN 12899-1 (Standard for Fixed Traffic Signs).
China: GB/T 18833-2012 (National Standard for Road Traffic Reflective Film).
Safety certification: such as CE, ISO 9001/14001.

Summary of application scenarios and advantages
PVC reflective film ensures the following parameters through the above parameters:
High visibility: Improve the sign recognition distance at night or in low light environments (such as diamond-grade reflective film can increase the sign visibility distance by 300%).
Long life: Reduce the cost of frequent replacement and adapt to multi-climate environments.
Compliance: Meet global traffic safety regulations and reduce the risk of accidents.
