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 a tube bird feeder?: Tube feeders are cylindrical in nature, and are made to hang from a branch or some other place, there are single tube feeders that can hold one type of seed, and 3 tube feeders that can hold 3 type of seed and attract more bird types to your back yard. Tube feeders are made of plastic or metal, and some are made to attract special kind of birds, like thistle bird feeder to attract cardinal birds. TUbe feeders can be made for clinging birds, or with perches, so it is important to decide what bird will you like to have in your yard. The size of the tube feeder will also mater.

Q: Are plastic tubes suitable for storing chemicals?: Yes, plastic tubes are suitable for storing chemicals as long as they are made from chemically resistant materials such as polypropylene, polyethylene, or PTFE. These materials can effectively withstand the corrosive properties of various chemicals and maintain their integrity, preventing any contamination or leakage. However, it is important to carefully select the appropriate plastic tube based on the specific chemical being stored to ensure compatibility and safety.

Q: What are the cost considerations when using plastic tubes?: Some of the cost considerations when using plastic tubes include the initial investment in purchasing the tubes, transportation costs, maintenance and repair expenses, and disposal costs. Additionally, the type and quality of plastic used can affect the price, as well as any customization or special features required. It is also important to assess the overall lifespan and durability of the tubes to determine the long-term cost effectiveness.

Q: Can plastic tubes be used for storing liquids?: Yes, plastic tubes can be used for storing liquids.

Q: We just got my dad an oxygen tank and we need to connect 5/8 tubing to regular (standard) oxygen tubing. Where do I but the part to connect the tubing? Do they even make something to connect the two? If not how would you go about connecting them?: It might help to know what kind of tubing you are working with (both ends). For metal there are various size reducers (flared and threaded). For rubber there are probably push on reducers, plastic may be a bit more difficult.

Q: Attempting to change the spark plugs in '00 Jeep Grand Cherokee. How do I get the plastic tubes off the plugs?: Pull on the big part not the wire. Good luck! Try turng them back and forth that my help. Thier stubern little shits!

Q: Can plastic tubes be used for hydroponic lines?: Yes, plastic tubes can be used for hydroponic lines. Plastic tubes are commonly used in hydroponic systems to transport water, nutrients, and other solutions to the plants. They are lightweight, flexible, and durable, making them suitable for various hydroponic setups. Additionally, plastic tubes are resistant to corrosion and can be easily cleaned, making them a practical choice for hydroponic applications.

Q: Are plastic tubes suitable for use with hot liquids?: No, plastic tubes are not suitable for use with hot liquids as they can melt or release harmful chemicals when exposed to high temperatures.

Q: Can plastic tubes be used for packaging food products?: Yes, plastic tubes can be used for packaging food products.

Q: Does the PVC-U drain plastic pipe need to be fabricated and installed?: PVC-U drainage plastic pipes shall be calculated for the installation of the pipe. The support shall be determined according to the laying method, drain pipe diameter, and the circumstances and location of the special placement.
