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: What is the maximum diameter of plastic tubes available?: The maximum diameter of plastic tubes available can vary depending on the manufacturer and the specific application, but it can typically range from a few millimeters to several inches.

Q: What are the common uses for plastic tubes in construction?: Plastic tubes are commonly used in construction for various purposes such as plumbing, electrical conduit, ventilation systems, and drainage systems. They provide durability, flexibility, and resistance to corrosion and chemicals, making them suitable for a wide range of applications in the construction industry.

Q: How do plastic tubes perform in extreme weather conditions?: Plastic tubes generally perform well in extreme weather conditions due to their durability, resistance to corrosion, and ability to withstand temperature variations. However, the specific performance may vary depending on the type of plastic used and the severity of the weather conditions.

Q: How do plastic tubes compare to nylon tubes in terms of strength?: Plastic tubes generally have lower strength compared to nylon tubes. Nylon tubes are known for their superior strength, durability, and resistance to wear and tear. They can withstand higher pressures and have better tensile strength, making them more suitable for applications requiring high performance and reliability.

Q: In the project embedment, the plastic line box and the plastic line pipe connection must use the mother to connect? What norms do you come from?: Plastic pipe bonding must be firm and tight, and in the pipe mouth plug plastic pipe plug, prevent grouting, plug pipe

Q: Are plastic tubes resistant to discoloration?: Yes, plastic tubes are generally resistant to discoloration due to their durable and non-reactive properties.

Q: Are plastic tubes suitable for underground installations?: No, plastic tubes are not generally suitable for underground installations as they may not possess the necessary strength and durability to withstand the pressure and environmental factors associated with underground conditions.

Q: Can plastic tubes be used for hydroponic lines?: Yes, plastic tubes can be used for hydroponic lines. They are commonly used as a cost-effective and durable option for delivering nutrient-rich water and solutions to the plants in a hydroponic system. Plastic tubes are flexible, easy to install, and resistant to corrosion, making them suitable for various hydroponic applications.

Q: What is the diameter range of plastic tubes?: The diameter range of plastic tubes can vary widely depending on the specific application and manufacturing process. However, they typically range from a few millimeters to several inches in diameter.
