Porous Sintered PTFE for Venting in Battery Applications
DeWAL® DW232DV product is a fully sintered, porous PTFE film that is thermally and chemically stable. Using the excellent environmental and chemical protection offered by PTFE, DW232DV incorporates pores to allow for controlled venting of air and vapor with excellent transfer and equalization of temperature and pressure.
Applications:
Due to the lack of expansion and stretching versus ePTFE, DW232DV is the perfect choice for dual stage venting systems in EV/HEV applications as the vent allows for rapid pressure relief in the event of catastrophic failure.
