Contact SupplierPolyethylene is a thermoplastic polymer consisting of long chains produced by combining the ingredient monomer ethylene. The ethylene actually converts to ethane as it takes its place in a polymer and straight sections of the polymer are the same structure as the simple chain hydrocarbons, e.g., propane, decane and other straight single-bonded carbon chains. As with any polymer, the structure of the resulting substance defies molecular description due to cross branching of the chains.
HDPE (High Density polyethylene) is defined by a density of greater or equal to 0.941 g/cm3. HDPE has a low degree of branching and stronger intermolecular forces and tensile strength.
Features & advantages of PE:
 Suitable for underground pipes through adjustment to local ground movement
 Impact-resistant and tough.
 Thermal resistant Application possible between -40°C & 80°C
 Smooth internal wall Low blockage risk due to low deposit / residue effects
 Application in open air unrestricted through colouring with carbon black
 Lower cost due to relative long life
 Non conductive
 Suitable for transport of polluted waste water
 No condensation possible during short periods of cooling
 Easy installation using butt-welding and electro-fusion techniques
 Environmental friendly
 Homogeneous welded joints - Pull tight and leak proof
 Prefabrication = Fast and cost-saving installation
 Light in weight = Cost saving in transport and handling
