XYC-75The oxygen index tester meets the requirementsGB/T2406Used to evaluate the combustion performance of polymers under specified test conditions, that is, to determine the volume percentage concentration of the least oxygen that the polymer can maintain combustion. It is applicable to the determination of combustion performance of plastics, rubber, fiber, foamed plastics, film, film and other materials. This instrument is an accurate, reproducible, and convenient detection device for determining the combustibility of polymers. This instrument can not only serve as a means of identifying the flame retardancy of polymers, but also as a research tool to gain a better understanding of the combustion process of polymers.
