Rogers PORON Helps Electric Auto Manufacturer Solve Charge Plug Problem Rogers PORON® AquaPro™ Foam Keeps Water Out of Battery Charge Plug
CUSTOMER PROBLEM:
An innovative electric car company was facing challenges with its vehicle battery charge plug. The existing design did not include any clips to hold it in place, so the closed-cell molded plastic failed due to a loss of the sealing material’s thickness (a property called “compression set”), allowing moisture to permeate the seal through the gap between the molded plastic and enclosure. Pre-launch testing of the new electric car revealed the problem. The manufacturer’s high standards required a quality, long-term solution that would allow them to meet their launch date and exceed the expectation of discerning customers.
THE ROGERS SOLUTION:
PORON® POLYURETHANE FOAMS.
The manufacturer incorrectly supposed that a closed-cell material with a "skin" would be better at sealing out moisture. Rogers' PORON® AquaPro™ 37 or 41 was a better choice for this application because the compressible foam gasket conformed more closely to the space between the plug and socket, sealing more completely than the very firm molded plastic plug or other materials like polypropylene or crosslinked polyethylene. The compression set resistance (see description) properties of PORON AquaPro materials allow it to retain its shape and seal over a much longer period of time than polypropylene or crosslinked polyethylene,providing moisture resistance and reducing the number of times the charge plug will need maintenance or repairs.
