Physical properties[edit]

Polyethylene is a thermoplasticpolymer consisting of long hydrocarbon chains. Depending on the crystallinity and molecular weight, a melting point and glass transition may or may not be observable. The temperature at which these occur varies strongly with the type of polyethylene. For common commercial grades of medium- and high-density polyethylene the melting point is typically in the range 120 to 180 °C (248 to 356 °F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 °C (221 to 239 °F).it is transprant.

Chemical properties[edit]

Most LDPE, MDPE and HDPE grades have excellent chemical resistance, meaning that it is not attacked by strong acids or strong bases. It is also resistant to gentle oxidants and reducing agents. Polyethylene burns slowly with a blue flame having a yellow tip and gives off an odour of paraffin. The material continues burning on removal of the flame source and produces a drip.^[3] Crystalline samples do not dissolve at room temperature. Polyethylene (other than cross-linked polyethylene) usually can be dissolved at elevated temperatures in aromatic hydrocarbons such as toluene or xylene, or in chlorinated solvents such as trichloroethane or trichlorobenzene.^[4]

Q: Are plastic tubes microwave-safe?: No, plastic tubes are generally not microwave-safe as they can melt or release harmful chemicals when exposed to high temperatures. It is recommended to use microwave-safe materials such as glass or ceramic when heating food or liquids in the microwave.

Q: How do you prevent plastic tubes from melting?: One way to prevent plastic tubes from melting is by using heat-resistant materials such as high-density polyethylene (HDPE) or polypropylene (PP) that have higher melting points compared to other plastics. Additionally, it is important to avoid exposing the plastic tubes to excessive heat sources or direct flames.

Q: Can plastic tubes be used for vacuum applications?: Yes, plastic tubes can be used for vacuum applications. However, it is important to choose the right type of plastic material that is compatible with vacuum conditions and has sufficient strength to withstand the pressure difference.

Q: Is there an instrument for measuring the leakage of underground plastic pipes?: There are such instruments, but not omnipotent, can solve the problem, depending on the actual scene. In general, Water Leakage big words, instrument can generally be detected, but if it is difficult to guarantee a certain small Water Leakage detected, after all, each device has a predetermined sensitivity, the sensitivity is lower than that of Water Leakage cannot be detected.

Q: PR plastic tubes, everyone said, permanent, a great harm to health, even drinking water is a problem?: 1) change the water pipe: the longer the PPR pipe is used, the greater the poison, or the regular flushing and disinfection of the old pipe.2) install pre filter and cabinet water purifier in old pipe line3) new home water pipes customers can study in Europe and the United States, the family installed plastic copper pipe (slightly higher price) or lined with copper PPR tube (moderate price). Because copper has excellent sterilization function and self-cleaning function, it is most suitable for family use.

Q: How do you prevent plastic tubes from cracking?: To prevent plastic tubes from cracking, it is important to handle them with care and avoid applying excessive force or pressure. Additionally, storing the tubes in a cool and dry environment can help minimize the risk of cracking. Using appropriate fittings and connectors that are designed to handle the specific type of plastic material can also contribute to preventing cracks.

Q: Im looking for plastic tubes like pvc, but clear. about 3ft in length. where can i find it?: Go to Home Depot or Lowes Home Improvement. They should be well stocked with what you are looking for and the staff are always willing to help customers. Just ask them if they have what you need and they will point you in the right direction.

Q: Can plastic tubes be used for irrigation systems?: Yes, plastic tubes can be used for irrigation systems. They are commonly used due to their durability, flexibility, and ability to resist corrosion. Plastic tubes are also cost-effective and easy to install, making them a popular choice for various irrigation applications.

Q: UPVC drain plastic pipes, can you use hot water?: Hot water is best to use PP plastic pipes, UPVC can only withstand the highest temperature of 55 degrees, but not long at this temperature, or it will accelerate the aging of the tube, bending, and even cracking.

Q: I need to buy plastic (or clear colored) plastic tubes with caps. Approximately 5 or 6 inch in length and close to 1 inch or close to it in width. Would appreciate any suggestions where I find it.: the hardware giants like Lowe's and the Ho Depot are your best bet ... go in the store and ask for plastic tubing==== HEY !! you might do better to go to a friendly pharmacy and get some clear plastic medicine bottles ... go and ASK ... and if this is
