1.Welding SST POROUS® vents type
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 |
