Jiangxi Dishi has a professional flame retardant experimental instrument, which can accurately test the performance of flame retardants. Its instruments and equipment can simulate different combustion environments and analyze the combustion characteristics of materials, such as evaluating the flame spread speed of materials through vertical/horizontal combustion tester. In addition, the experimental instrument of the stone can also test the charring, shell formation and porcelain formation effects of the flame retardant at high temperature to ensure its reliability and safety in practical application.
