TPC in wood impregnation:
As discussions intensify in Europe surrounding the ban of various compounds in fire retardants, the demand for environmentally friendly solutions has reached new heights. At Jungbunzlauer, we are dedicated to innovation that aligns with these global trends – especially as the construction industry increasingly embraces natural building materials like wood.
Softwood is a widely used construction material, yet its inherent flammability poses significant challenges. Traditional flame retardants often contain chemicals that raise environmental and health concerns, driving the search for alternatives that not only comply with safety standards but also promote sustainability. Initially recognised for its effectiveness in controlling the burn rate of cigarette paper, tripotassium citrate (TPC) has undergone extensive research and trials, revealing its remarkable potential in wood applications. TPC provides an eco-friendly solution that does not compromise performance. When wood is treated with a TPC solution, it not only resists ignition but also forms an intumescent char layer, creating an additional barrier against fire.
Our rigorous testing with solid wood, veneer, and chipped wood has yielded impressive results: the TPC solution achieved Euroclass B, the highest classification for combustible materials, while producing minimal smoke and no burning droplets.
As a leading producer of TPC, we are thrilled to offer a natural, food-approved solution that is easy to handle and meets the stringent demands of the modern construction industry. Jungbunzlauer is at the forefront of paving the way for a safer, greener future in fire retardant technology.
