Burning Resistance
The composite structure provides Vista PE-AL-PE multi layer composite
pipes with a much better burning resistance as compared to all other
polyethylene pipes. It may reach up to Grade B1 of GB8624 - stipulations
for wire & cable conduit plastic material.
Malleability
Uniquely, Vista PE-AL-PE multi layer composite pipes are completely
malleable & can be easily curved by hands. They can bend down to a
radius equivalent to 5 times the diameter of the pipe.
Permeability
The Aluminum core of Vista composite pipes guarantees static resistance
& light & oxygen tightness. It acts as a barrier against the entry of
any contaminant.
UV Resistance
Vista composite pipes are UV stabilized / UV resistant.
