Oxygen Barrier Property of Multilayer Pipe
Oxygen barrier property of multilayer pipe consisting of "Soarnol®" is shown in the following.
(1)Test Method
Sample
| Layer Structure | : | XPE / Tie / EVOH (Outermost) |
| EVOH | : | Soarnol(29mol%,38mol%,44mol%) |
OTR Measurement
| Apparatus | : | MOCON OX-TRAN 10/50 |
| Condition | : | Length of pipe=1m,Temp.=20deg C |
| Humidity(Inner)=100%RH, Humidity(Outer)=65%RH |
(2)Result
| Soarnol | OTR （ｃｃ/m.day.air） |
Thickness of Soarnol （ µm） |
|---|---|---|
| Soarnol 29mol% | 0.0004 | 158 |
| Soarnol 38mol% | 0.0008 | 144 |
| Soarnol 44mol% | 0.0012 | 158 |
