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 suitable for outdoor applications?: Yes, plastic tubes are generally suitable for outdoor applications. They are often made from durable materials such as PVC or HDPE which are resistant to weather conditions, UV rays, and corrosion. Plastic tubes can be used for various outdoor purposes like irrigation systems, drainage systems, outdoor plumbing, or even as protective sleeves for electrical cables. However, the specific type of plastic tube should be chosen based on the intended application and environmental factors to ensure long-term durability and performance.

Q: Am I even safe to drive to the mechanic or should I just two it? Holy crap, that could have been there for months for all I know since I last checked.: You okorder /

Q: Are plastic tubes suitable for use in the automotive industry?: Yes, plastic tubes are suitable for use in the automotive industry. Plastic tubes offer several advantages such as being lightweight, resistant to corrosion, and easy to install. They are widely used in various automotive applications, including fuel and brake lines, coolant systems, and air intake systems. Additionally, plastic tubes can be manufactured to meet specific performance requirements and are often more cost-effective compared to other materials.

Q: How do plastic tubes compare to glass tubes in terms of strength?: Plastic tubes are generally considered to be less strong than glass tubes. Glass tubes are known for their durability and resistance to breakage, making them a stronger and more reliable option for various applications. However, the specific strength of plastic tubes can vary depending on the type of plastic used and its thickness.

Q: I heard I could level my mobile home by using clear plastic tubing and red drink mix. Is that possible, and if so, how?: fill the tubing and have someone hold the tubing at one corner of the home outside. have them tell you when the level of the liquid is at the height of the trailer edge. where the liquid is at your end is where the height of the trailer should be to be level...easier to rent a cheap transit... edit: i guess 30 years of using one is easier than explaining how...

Q: What is the average lead time for manufacturing plastic tubes?: The average lead time for manufacturing plastic tubes can vary depending on various factors such as the complexity of the design, the quantity needed, and the production capabilities of the manufacturer. However, a typical average lead time for manufacturing plastic tubes ranges from a few days to a few weeks.

Q: Are plastic tubes tamper-evident?: Yes, plastic tubes can be tamper-evident. They are often designed with features such as seal caps, shrink bands, or breakable tabs that indicate if the tube has been opened or tampered with.

Q: I need to find a wholesaler who sells clear plastic tubes, like what you would find buttons in in a craft store (needs to have a lid). They need be be about two inches in diameter, and 6-12 long. I've tried google, clearbags, and every resource I can think of, but I'm coming up short. Help is appreciated!: Ask other stores where they order there's from. Sure it's going to a competitor for help but when your desperate you gotta go!

Q: What are the commonly used indoor plastic drainage pipes in the market, as well as the advantages and disadvantages?: The application of drainage plastic pipes is carried out in place of ordinary cast iron pipes. At present, drainage plastic pipes can be used in buildings under the height of 100m, but the progress in different areas is very uneven. When the building height is greater than or equal to 100m of high-rise buildings and unsuitable for drainage plastic pipe, flexible seismic drainage cast iron pipe can be adopted.

Q: Are plastic tubes suitable for pharmaceutical dispensing?: Yes, plastic tubes are suitable for pharmaceutical dispensing. They are commonly used in the pharmaceutical industry due to their versatility, durability, and ability to protect the integrity of the medication. Plastic tubes provide a hygienic and secure container for storing and dispensing various pharmaceutical products, such as creams, ointments, gels, and liquids. Additionally, plastic tubes can be easily sealed and labeled, ensuring accurate dosage and identification.
