1When there are fluctuations in temperature, the surface may wrinkle slightly, as elastomeric products expand and contract in these circumstances. However, these superficial changes do not have any impact on the performance of the material. The wrinkles usually disappear as soon as the plant is heated to its original operating temperature. 2For temperatures below -50 °C please contact our Customer Service Center to request for the corresponding technical information. 3In outdoor applications the colour may fade. This does not have any impact on the functionality of the covering or the insulation material. | ||||||||
