Rubber foam
Rubber foam insulation board has the characteristics of heat resistance, cold resistance, and flame retardancy. According to its fire resistance level, there are different classifications, B2 level, if the oxygen index is slightly lower, it can be achieved as a flame retardant material. The so-called oxygen index means that if this material wants to burn, it needs to reach a certain oxygen concentration. The higher the oxygen index, the better the flame retardant performance of this material. More importantly, its thermal insulation performance is also very good, mainly because the thermal conductivity is low, and the temperature has reached 150 degrees or more, and it can be used for a long time.
