Product Data Sheet
DeWAL® DW232PA
Porous Sintered PTFE for
Automotive Battery
Venting Applications
DeWAL® DW232PA product is a fully sintered, porous
PTFE film that is thermally and chemically stable. Using
the excellent environmental and chemical protection
offered by PTFE, DW232PA incorporates pores to allow
for controlled venting of air and vapor with excellent
transfer and equalization of temperature and pressure.
Due to the lack of expansion and stretching versus
ePTFE, DW232PA is the perfect choice for EV/HEV
battery emergency decompression vents.
• Venting and equalization of enclosed spaces while
resisting thermal cycling fatigue
• Rapid fracture under pressure allowing for emergency
decompression of an enclosed space
• Excellent thermal and chemical environmental
resistance
Applications:
• EV/HEV battery emergency decompression
vents.
