Safety management in the mining, petroleum and chemical industries is extremely strict. Ordinary reflective stickers are often prohibited due to their flammability. This product specially uses flame-retardant substrates and adhesive systems, passing the EN 533 flame retardant test and achieving Class 3 level (flame spread speed ≤ 100mm/min after contact with open flame, and no droplet ignition phenomenon). The product also maintains high reflective performance, with an inverse reflection coefficient of ≥ 150 cd/lux/m², ensuring high visibility for personnel and equipment during underground or night operations. The surface is resistant to chemical corrosion and can withstand the erosion of mine water, drilling fluid and common solvents. The product is suitable for reflective strips on miner's uniforms, identification marks for underground equipment, contour markings for oil tankers and pipeline warnings in refineries. The working temperature range is -20°C to +70°C, adapting to extreme climates in major mining regions worldwide. We offer roll materials in widths ranging from 5cm to 20cm, with colors mainly in silver-gray and yellow, in line with international mining safety practices. Each batch of products comes with an EN 533 test report and CE declaration. For B-end mining suppliers and PPE distributors, we provide long roll bulk and customized cutting services, significantly optimizing your inventory turnover.
