High temperature stabilized polyethylene PE-RT type II 5-layer pipe, manufactured

according to EN ISO 22391 (application class 4/6 bar, according to ISO 10508). The

intermediate layer is an EVOH oxygen barrier.

Use

The POLYSUPER BASIC pipe is a pipe of 17 mm diameter consisting of an inner layer

of second-generation PE-RT (polyethylene for high temperatures type II), an EVOH

intermediate layer consisting of an oxygen barrier and an external protective layer of

second-generation PE-RT, layers joined together by two additional layers of adhesive.

The pipe thus obtained is a 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;

•

The second-generation PE-RT (type II) is a particularly durable product especially

at the typical temperatures of radiant systems;

•

The use of PE-RT allows an extremely easy installation of the pipe.
