High Density Polyethylene Pipes (HDPE)
The HDPE is a polymer which is characterized by:
-
Excellent thermal and chemical resistance.
-
Very good impact strength.
-
It is solid, colorless, translucent, almost opaque.
-
Very good processability, ie they can be processed by methods used for thermoplastic formed as injection and extrusion.
-
It is flexible, even at low temperatures.
-
It is tough.
-
It is more rigid than low density polyethylene.
-
Presents difficulty printing, paint or paste over it.
-
It is very light.
-
Its density is equal to or less than 0.952 g/cm3.
-
Not attacked by acids, water resistant to 100 ° C and most of the ordinary solvents.
HDPE pipes are designed to work buried with a lifespan of at least 50 years and even under certain conditions we can say that the total period is still more.
