In general, HDPE molecules have between 700 and 1,800 monomer units per molecule, whereas UHMW molecules tend to have 100,000 to 250,000 monomers each. The chains of UHMW align in the same direction. The bonds between the chains are not very strong however, because they are so long there are more bonds holding it together then polyethylene with shorter chains.
PEX C. Cross-linking here is initiated by subjecting HDPE tube to an electron beam or gamma radiation. The PEX C method is not as common as the first two methods and you may not run into it, but know it’s another type of PEX tube that’s available.

26/9/· Cross-Linked Polyethylene (PEX or XLPE) is a flexible plastic (polymer) tubing pipe primarily used in both hot and cold-water distribution pluing systems. During the past two decades in the United States, PEX has also become a common alternative to copper, polyvinyl chloride (PVC), and chlorinated polyvinyl chloride (CPVC) for use as potable (drinkable) cold and hot water system piping.
"Black polyethylene" seems to commonly refer to HDPE pipe, which is pretty comparable to PEX. "Just" PE pipe is cheaper and less durable than HDPE - I''d advise against that underground. PEXa ("Uponor/Wirsbo", "ProPEX", "F1960") is the best option, especially underground and in places with a potential for freezing, since it simply expands and contracts instead of bursting and leaking.
PEX/AL/PEX Pipes Crimpex PEX/AL/PEX Multilayer pipe consists of a Continuous butt-welded aluminium core with an inner and outer layer made of HDPE (polyethylene) that has been cross-linked using silane and can be high temperature-resistant.
