Good stability and anticorrosion
In use for a long period of time, it will not be aged, won't break down and produce harmful substances. Its chemical performance is very stable. After absorbing water and corrosion degradation,
its performance is still stable. Under the environment of high temperature, it can still maintain its superior performance. According to relevant data, XPS extruded thermal insulation boards even
after used for 30 ~ 40 years, still can maintain the outstanding performance, and won't decompose or mildew and no volatile toxic substances.
