Stability to the temperature: Globe panels are used in a range of continuous temperatures normally included between -40° C and +110° C. Long exposures to the temperatures could cause deformations to the foam or to the coats, but without causing sublimation or fusion.
Aspect: prolonged exposure of the polyurethane foam to UV rays can cause surface oxidation, the phenomenon does not affect the basic characteristics and performance of the panel.
