450gsm 500Dx500D 28x28 Matte Black Bottom Polishing Scraping Cloth

Technical Specifications:

The high-performance biaxial polyester base fabric is woven with a 28×28 high-density, compounded with a matte black PVC film layer. The surface is flexible and smooth, while the back is rough with particles. Its thickness and light-shielding property are significantly better than conventional lamp cloth. Specifically designed for high-precision outdoor printing, it has outstanding wind pressure resistance and is suitable for long-term exposed giant advertising projects. 

Super-Large Outdoor Advertising: Suitable for long-term exposure scenarios such as highway single-column (billboard) structures and airport giant billboards. With its 500D high-strength base fabric and 28×28 high-density weaving structure, it offers excellent wind and tear resistance (≥2100N/5cm), ensuring stability in extreme weather conditions. 
High-End Commercial Displays: Ideal for brand flagship store facades and luxury car dealership backdrops, its matte black base enhances color contrast and avoids reflective interference, elevating brand visual appeal. 
Industrial Protection: As a corrosion-resistant cover for outdoor equipment in chemical plants, it is resistant to acid and alkali and UV aging, making it suitable for harsh industrial environments. 

1. Ultra-high wind and tear resistance: 500D biaxial polyester base fabric combined with 28×28 high-density weaving, with a warp tear strength of ≥2100N/5cm, specially designed for large outdoor advertisements (such as billboards and airport billboards), maintaining structural stability even in extreme weather. 
2. Black background light-shielding technology: The matte black background coating completely blocks light transmission, ensuring the image colors are saturated without blooming, and the visual impact is stronger when lit at night. 
3. Industrial-grade weather resistance: UV resistance and salt spray corrosion resistance, suitable for high-corrosion environments such as chemical industrial zones and coastal areas, with an outdoor service life of 5 years.
