PEX pipe is made from High Density Poly-Ethylene (HDPE). PEX is the short term for Cross-linked (hence, “X”) Poly-Ethylene (PE). The cross-linking process improves the chemical and temperature performance ratings of the polymer and provides flexibility and additional strength.

MUNICIPEX VS. HDPE MUNICIPEX ® – THE PROVEN WATER SERVICE ALTERNATIVE Crosslinked polyethylene (PEX) is a polyethylene (PE) material which has undergone a change in molecular structure in which polymer chains are chemically linked. This Puhui Pipe manufacturer in China
PEX is a reliable pipe made from HDPE (High Density Polyethylene). PEX has been used successfully throughout the world for many years. It is the most preferred pluing option for domestic purposes, though it is not meant for outdoors and could get damaged if it is kept outside under UV rays of the sun.
Choose Your Pipe, Pex-al-pex or Pert-al-pert The two choices of pipe we recommend using for your undefloor water system is either PEX-AL-PEX, or PERT-AL-PERT. PEX-AL-PEX pipe is designed specifically for use with wet underfloor heating systems, very high compressive strength (30tonnes / m2), light weight, high efficiency and low cost make this thermal board an ideal choice when fitting heating Puhui Pipe manufacturer in China

14/7/2016· Key Difference – PVC vs HDPE PVC and HDPE are two types of polymeric synthetic plastic materials which are used in many industrial appliions. The key difference between HDPE and PVC is the difference in density; HDPE is denser than PVC, and this leads to differences in their physical properties and industrial appliions.. In addition, the difference in chemical structure and Puhui Pipe manufacturer in China

"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.
