A commonly asked question is whether the H48-2 series can be reworked. With care, all parts of this series can be reworked. However, T-Global strongly recommends that the pads are replaced after use, as this prevents contamination. Another frequently asked question is the shelf life of the product. The shelf life of all gap fillers without an adhesive layer is two years. For gap pads with an adhesive, this is reduced to one year. Also commonly discussed is if the the pads soften with temperature. Up to the maximum working temperature, as specified on the individual product datasheet, the materials will not suffer with temperature increase.
