Radiation heat protection operations near high temperatures and fire scenes. Utilizing patented aluminum coating technology, the aluminum film is tightly bonded with aramid and carbon fiber fabrics, offering high thermal stability, wear and scratch resistance, and does not flake after prolonged friction. High water stability and a high glossy surface ensure excellent thermal reflection efficiency. This garment consists of five layers of fabric, providing fire-retardant and heat-insulating properties. The scientific combination of fabrics balances protection, lightweight performance, comfort, and occupational health safety, making it an advanced and ideal material combination. The complete suit is heat-resistant with high flame-retardant stability and no harmful by-products.
