Enclosure Sealing for EV Charging Points

While the number of EV charging station installations is increasing, it’s crucial to ensure they operate reliably to meet the growing demand of EV drivers and fleet operators. As many installations are outdoors, they require robust protection against corrosion and reliable safeguarding from extreme environments. Our closed-cell compressible foam tapes offer quick and precise assembly, rapid curing time, no squeezing or oozing, and permanent sealing against water, dirt, and air. These materials remain flexible in both hot and cold climates, ensuring the functionality of the enclosures.
