PE-Xa stabilized polyethylene 5-layer pipe, cross-linked by means of high pressure

peroxide, manufactured according to EN ISO 15875 (application class 4/8 bar,

according to ISO 10508). The intermediate layer is an EVOH oxygen barrier.

Use

POLYSUPER pipe is a 17-mm diameter pipe, but also available in 20 and 25 mm,

consisting of an inner layer of PE-Xa, type A cross-linked polyethylene, an intermediate

layer consisting of an EVOH oxygen barrier and an outer protective layer of second-

generation PE-RT, the layers being bonded together by two additional layers of

adhesive.

The pipe thus obtained is a particularly suitable pipe for underfloor heating systems

because:

• The particular 5-layer construction allows the protection of the oxygen barrier that,

not being outside, cannot therefore be damaged during job-site operations;

• PE-Xa is a particularly durable product especially at the typical temperatures of

radiant systems;

• The use of PE-Xa allows easy installation of the pipe, especially when compared to

other types of cross-linked polyethylene pipes.
