It features: high temperature
resistant(120℃,fire retarded),
anti-abrasion, anti impact
and anti-aging. The close cell
bubbles are foamed by cross
linked PE (specially formulated
). The inner pipe is foamed
continuously without seam and
closely welded with the outer 2
layers. The insulation pipe has
no air pocket among layers. The
special structure ensures low water absorption and good thermal insulation
. The insulation pipe can work under
-70-120℃. The good thermal insulation
performance ensures no dewing, which
avoid contamination of condensed water.
The insulation is tested under 200 Hours
of irradiation of Xenon lamp. No corrugate
, pin hole, cracks and pulverization are
detected. It is kind of evidence of the
8-10 year of life time under normal use.
It complies with the EU ROHS directive.The
fire retarded insulation can reach the Level
of UL-HF-1 (US) and M1(France).
The 3-layer product is composed of inner pipe
(water crosslinked), middle layer (irradiation
crosslinked) and outer UV resistant PE film.
