Are SERFs suitable for hot conditions?

Yes, self-engaging reclosable fasteners (SERFs) are designed to perform well in hot environments. The functional surface (including the engagement elements) remains stable and engaged at temperatures ranging from +90 °C (195 °F) to +150 °C (302 °F), depending on the specific construction of the fastener.

For elevated temperature stability, the following example factors should be considered:

• Duration of exposure: How long will the fastener be exposed to high temperatures?
• Static loads: Loads that remain stationary or hanging
• Dynamic loads: Loads that shift or apply sudden force
• Shear force: Forces pulling across the fastener’s surface, which can be static or dynamic
• Engagement/disengagement needs: Will the fastener need to resist disengagement or is it required to engage and disengage at high temperatures?

Mounting methods for hot environments

When using SERFs in hot conditions, consider the durability of the mounting method. Adhesives with specific chemistries designed for high-temperature exposure are available. In addition, clips and extruded profiles made from materials that behave similarly to the SERFs offer effective solutions. Other methods such as sewing or welding can be used, depending on the product assembly.
