We are proud to introduce our latest innovation in advanced testing solutions – the new series of Limiting Oxygen Index (LOI) Chambers for enhanced plastics testing. This cutting-edge line of instruments has been carefully designed to precisely measure the combustion performance of a wide range of materials, including plastics, rubber, fibers, foamed plastics, films, textiles, and wood under specified test conditions.
Fire safety testing is critical for materials used in electrical cables, consumer goods, and construction applications. The Limiting Oxygen Index (LOI) test is recognized as one of the most efficient and reliable methods for assessing flame retardancy, widely adopted in plastics and cable manufacturing industries for routine quality control and material validation.
By accurately determining the minimum oxygen concentration required to sustain combustion, our new QualiLOI chambers provide valuable insights into the flame retardancy of polymers, serving as an essential tool for material evaluation and research.
