①.Welding SST POROUS^® vents with substrate

Instruction

D =  OD；

Y =  (e-PTFE) vents membrane；

Z = Substrate；

b = Typical thickness

 Tolerance： +/- 0.25mm

Welding surface recommendation：

ⅰ.Welding SST POROUS^® vents with substrate: Hot melt or ultrasonic welding with the target plastic housing by the z (support material) surface

ⅱ.100% welding SST POROUS^® vents does not distinguish both sides

Note: Different plastic materials need to choose different types of support materials, available for technical solution www.spider-amoy.com through SST sales engineer

Notes

※ The IPx7 resist the effects of soaking for 30 minutes in water up to 1meter deep

※ The IPx8 is usually agreed testing with the end user

※ The test area is 1cm2, and the test time is 50sec

※ The actual test air flow with a test area of 1cm2 application
