Oil repellent flame retardant rainwear is a specialized category of protective work clothing engineered to deliver dual-core protection against harsh outdoor industrial environments, combining exceptional oil resistance, flame retardancy, and waterproof performance for comprehensive workplace safety. Crafted with high-density modified polyester fabric integrated with professional flame retardant additives and nano oil-repellent coatings, this rainwear permanently locks in flame-resistant properties without compromising its waterproof and oil-proof capabilities. Unlike ordinary rain gear that only blocks water, it effectively repels various industrial oils including machine oil, hydraulic oil, and lubricating oil, preventing oil stains from penetrating the fabric and causing secondary safety hazards such as combustion or skin adhesion. The flame retardant technology adopts durable intrinsic flame retardant treatment, which does not fail after repeated use and cleaning, ensuring stable fire resistance to block open flames, spark splashes, and high-temperature heat radiation in industrial scenarios.
