Chapter 1Uponor PEX PropertiesUponor PEX PropertiesPEX is an acronym for crosslinkedpolyethylene. The “PE” refers tothe raw material used to makepolyethylene; the “X” refers to thecrosslinking of the polyethyleneacross its molecular chains.The molecular chains are linkedinto a three-dimensional networkthat makes PEX remarkably durablewithin a wide range of temperaturesand pressures.Figure 1-1: PEX-a(Engel) 80% crosslinkedCurrently, three methods exist forproducing PEX. Engel or peroxide method (PEX-a) Silane method (PEX-b) Electron beam (e-beam) orradiation method (PEX-c)The pipe’s shape memory alsooffers the unique opportunity forProPEX fitting connections. Shapememory allows PEX-a to expand andthen shrink back to normal size —creating strong, durable and reliablefitting connections.Finally, PEX-a pipe offers moreresistance to crack propagation (howa crack grows) than PEX-b or PEX-cpipe. A crack that occurs in PEX-apipe is the least likely to grow overtime and cause leaks or damage.All three processes generate pipethat is crosslinked to various degreesaccording to ASTM F876 and F877standards.Uponor manufactures Engel-methodPEX-a pipe. The PEX industryconsiders this pipe superior becausethe crosslinking is done duringthe manufacturing process whenthe polyethylene is in its amorphicstate (above the crystalline meltingpoint). Accordingly, the degree ofcrosslinking reaches more than80%, resulting in a more uniformproduct with no weak links in themolecular chain.Stress ResistancePipe installed in commercialapplications must be capableof withstanding the stresses thatresult from installation withincommercial buildings.Typical stresses include: Expansion and contractionthat result from repeatedheating and subsequent coolingof the heat-transfer fluidPEX-a DistinctionsThe properties of PEX-a pipe make itthe most flexible PEX on the market.This flexibility allows the tightestbend radius available — six timesthe outside diameter of the pipe.Its flexibility also greatly reducesinstances of kinked pipe. And in therare instance of a kink, the thermalmemory of PEX-a allows kink repairwith a simple shot of heat from aheat gun.Plumbing Design Assistance ManualFigure 1-2: PEX-b(Silane) 65-70%crosslinked Mechanical abrasion, shearingand stretching that occurs asa result of installation, normalstructural movement and heatingand cooling from seasonalweather changesUponor PEX provides the durabilityand reliability that is needed for theseapplications and currently holds theunofficial world record for long-termtesting at elevated temperature—Chapter 1 – Uponor PEX PropertiesFigure 1-3: PEX-c(Radiation) 70-75%crosslinkedand pressure. From 1973 to 2009,the pipe was subjected to ongoingtesting at 203 F (95 C) at 175 psiby Studvik in Sweden and BASFin Germany.Cleanliness ofUponor PEXThe quality materials and exactingprocess used in manufacturingUponor AquaPEX yield remarkablyclean water-distribution piping.Uponor PEX piping is made bycrosslinking high-density,highmolecular weight, 100% virginpolyethylene flake.

Hydrostatic Temperatureand Pressure RatingsInterpolation MethodPressure ratings at differenttemperatures are determinedby using a linear relationshipbetween the standard-grade ratings.See Table 1-5 for interpolatedtemperature and pressure ratings.Through scientific research andhistorical experience, hydrostaticdesign basis (HDB) ratings havebeen shown to be useful indicatorsof relative long-term strength ofthermoplastic materials when testedunder the conditions specified in testmethod ASTM D2837. The HDB isused to determine the temperatureand pressure ratings of a specificmaterial. These temperature andpressure ratings are based on anextrapolated life of 50 years.Excessive Temperatureand Pressure CapabilityStandard PPI TR-3 defines the policiesand procedures for developing HDBratings for thermoplastic pipingmaterials or pipe.Uponor maintains standard-graderatings for Uponor AquaPEX pipingas tested in accordance with TR-3.Uponor AquaPEX carries the followingtemperature and pressure ratingsshown in Table 1-4.Note: Uponor EP and LF Brassfittings carry the same temperatureand pressure ratings as UponorAquaPEX pipe.In accordance with ASTM F876Standard Specification for CrosslinkedPolyethylene (PEX) Piping, theexcessive temperature and pressurecapability of Uponor AquaPEX is210ºF at 150 psi (99ºC at 10 bar).This standard requires that UponorAquaPEX piping maintain itsintegrity for a period of 720 hours(30 days) at 210ºF (99ºC) at150 psi (10 bar). If installed asdirected, Uponor AquaPEX willwithstand these conditions.Note: Excessive temperature andpressure requirements are alwayssubject to approval by local buildingcodes (e.g., temperature andpressure-relief valves).Temperatureand Pressure 179/12.3Table 1-5: InterpolatedHydrostatic Temperature andPressure Ratings for UponorAquaPEX PipingASTM F876 Temperature and Pressure Ratings for SDR9 PEXRatedTemperatureHydrostatic DesignStress (HDS) psiPressure Rating for Waterpsi73.4 F/23 C630160180 F/82 C400100200 F/93 C31580Table 1-4: Hydrostatic Temperature and Pressure Ratings for Uponor AquaPEX PipingThese listings are published in PPI TR-4, a culmination report of the listings that are maintained with PPI.Plumbing Design Assistance Manual—Chapter 1 – Uponor PEX Properties3
