HDPE | LyondellBasell

2 HDPE is characterized by a linear polymer chain with few branches, and contains smaller amounts of comonomers such as butene, hexene or octene. HDPE grades are used in a variety of processing techniques such as extrusion, extrusion blow molding, injection and rotational molding.

2 In the early 1950s, high density polyethylene (HDPE) was developed and today blow molding is the largest user of HDPE, which is the largest volume ther-moplastic produced in the world, with over a billion pounds produced worldwide. Blow molding, until the last few years, was the main plastic process utilized to produce a hollow object.

2 HDPE is morderately viscous. When it is forced at high speed through a narrow die gap, the HDPE melt is sheared at a fast rate; at this point it appears to have a low viscosity. Then, when it hangs from the die as a blow molding parison, under practically no shear, the same HDPE appears to be very viscous.

Control Oxidation of HDPE Parts | Plastics Technology

2 Nature of The ProblemOperating ProceduresStart-Up & MaintenanceResponsible ShutdownAbout The AuthorLike other organic materials, HDPE will char and turn black after a certain amount of heat exposure. Once oxidized, the material wants to stick to metal in the flow path, which results in more oxidation and, eventually, burning. Thus, the first priority is to prevent the initial oxidation from occurring. Blow molding grades of HDPE are among the most robustly stabilized against oxidation, because up to 35% regrind is typically used in this process. This multiple-pass use of regrind is unique to blow molding and is unlike any other conversion method. But poor operating and maintenance procedures can consume the antioxidant protection and lead to burning. Figure 1 shows a bottle blow-out caused by burn contamination. The leak detector caught this bad part. Even more problematic is an HDPE bottle that turns into a “weeper” while in storage. These types of problems can be avoided by employing special monitoring techniques and process procedures to help control oxidation. See full list on ptonline.com Since cooling times determine the overall molding cycle, it makes economic sense to put the least amount of heat possible into the melt so there is less to remove. A cooler melt also minimizes the rate of oxidation. But there are limits on how low you can go, such as excessive amperage on the drive motor and excessive head pressure. Too low a melt temperature can also lead to poor rewelding of the melt at the knit line or in the pinch-off. Loss of gloss and thin corners due to poor extensibility of the melt also put limits on reducing melt temperature. Melt is heated by shear forces inside the machine, not just by the heater bands on the outside. Fill pressure for accumulator machines and backpressure for reciprocating-screw units should be kept as low as possible to minimize shear heating. Another familiar factory scenario illustrates how oxidation can occur. The mold-change crew gets a late start due to other issues and then snaps a head bolt. It is now 7:30 p.m. and everyone is t... See full list on ptonline.com A 35- or 50-lb head cannot come up to temperature as fast as a 120-mm or 150-mm extruder, so why start heating both at the same time? That just leaves melt baking in the extruder while the head warms up. Alternatively, use a two-step ramp-up profile when you set up your extruder temperatures. Once the operating temperatures and soak-in times are reached, start the machine up promptly. If you can’t start molding right away, use periodic purges to keep fresh resin in the barrel and head. Keep your temperature controllers calibrated. If a barrel cooling system is provided, make sure it works as designed. Keep an eye on screw and barrel wear by keeping an output test log for each machine. Backflow over worn screw flights requires more rpm to deliver melt at the same rate and causes a great deal of localized shear heating. Heat-zone temperature override is the usual symptom of a worn screw and often leads to burning problems. If the screw is pulled, record the flight diameters. A simple... See full list on ptonline.com When it comes to shutdown, probably the worst thing you can do is flip the machine’s power off and walk away. Yet this is not uncommon. Although blow molding grades are well stabilized with antioxidant additives, the antioxidant is gradually consumed during heat exposure. So regrind, which may have been through several heat histories, does not have the same oxidation protection as virgin resin. Thus, it makes sense to stop the regrind feed prior to shutdown, leaving only virgin in the system. The same goes for color concentrate. The carrier resin for the concentrate is not normally a blow molding grade with a robust antioxidant level. Film-grade resin is commonly used as the carrier and has less antioxidant protection. If possible, drop the heat levels on shutdown by 50° to 75° F and turn on the cooling system. Purging at low rpm will remove latent heat from the system, but watch the amps on the extruder drive motor so you don’t overload it. Banking the heat at approximately 100° be...
