Ⅰ.Features:
EVOH pipe adopts five-layer(pipe-AD-EVOH-AD-pipe) & three –layer (pipe-AD-EVOH) co-extrusion technology to extrude the PB, PEX and PE-RT oxygen barrier pipes of diameter range of 16-63mm and use special screw and dies for the oxygen barrier material.

II. Advantages:
1.Anticorrosion,especiallyresistant to electrochemical corrosion
2.Low heat dissipation and friction loss
3.Thermal memory
4.Quiet water flow
 5.Nontoxic and safe
 6.Flexibility for easier and faster installation
7.Fewer fitting for less chance of leaks
 8.Lower installation costs
9.Wonderful oxygen resistance

III. DIN 4726 Test
Provide condition 40°C 
 humidity of outer space -65%  inner space- 100%,
Pipe size: OD20mm 
ID15mm
Average thickness of EVOH layer: 188μ M
DIN standard: ＜0.1g/m³/day
Palconn Pipe Texting Result = 0.003g/m³/day

IV.Application:
EVOH oxygen barrier pipe is recommended for hydronic radiant panel heating systems utilizing water or an *antifreeze solution as the heat transfer media. Piping may be installed in concrete, gypsum based lightweight concrete, sand and in or under wood flooring or behind wallboard or plaster. O2Barrier EVOH may also be used as transfer lines for baseboard heating systems with a maximum operating temperature of 80 DEGREE.
