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: Can plastic tubes be used for sewer lines?: Yes, plastic tubes can be used for sewer lines. Plastic pipes, such as PVC (polyvinyl chloride) or HDPE (high-density polyethylene), are commonly used in modern sewer systems due to their durability, resistance to corrosion, and ease of installation. Plastic tubes offer a cost-effective and efficient solution for sewer line applications.

Q: Are plastic tubes safe for storing cosmetics?: Yes, plastic tubes are generally considered safe for storing cosmetics. They are commonly used in the industry due to their durability, flexibility, and ability to protect the product from contamination. However, it is important to ensure that the plastic used is of high quality and free from harmful chemicals such as BPA. Additionally, it is advisable to check the compatibility of the plastic with specific cosmetic formulas to prevent any potential reactions or degradation of the product.

Q: Are plastic tubes resistant to staining from food dyes?: Yes, plastic tubes are generally resistant to staining from food dyes.

Q: What is the difference between waste pressure plastic pipe and PVC pipe?: PE pipe safety, flexibility and impact resistance are better than PVC, can be used as underground gas pipeline, tap water pipeline;

Q: Can plastic tubes be bent without breaking?: Yes, plastic tubes can be bent without breaking, depending on the type and quality of the plastic used. Some plastics, such as PVC or polyethylene, are more flexible and can be bent to certain angles without breaking. However, it is important to note that excessive or sharp bending can lead to stress on the plastic, potentially causing it to crack or break.

Q: Can plastic tubes be used for display stands?: Yes, plastic tubes can be used for display stands. Plastic tubes are lightweight, durable, and can be easily customized to fit different display needs. They are commonly used in various industries, such as retail, trade shows, and exhibitions, for showcasing products or promotional materials. Plastic tubes offer a cost-effective and versatile solution for creating attractive and functional display stands.

Q: Can plastic tubes be used for agriculture applications?: Yes, plastic tubes can be used for agriculture applications. They are commonly used for irrigation systems, drainage, and as protective covers for plants. Plastic tubes are durable, lightweight, and can be easily installed, making them a practical choice for various agricultural needs.

Q: My little brother just got 2 gerbils. One of them is fine going in the tubes and coming back down, but the other won't go up. He will climb down if you put him up there, but he won't climb up on his own. Their sleeping area is on the top floor, and there's another floor with his food and water on it. The water bottle will only fit in that spot, so there's no other way to move the bottle. Also, how do i get them to figure out how to use a water bottle?: Until your gerbil gets the hang of it, put the food on the level he does have access to. At times all it takes is a little time for them to realize there's more to their home. Once he does, he'll be able to have the food where it currently is. I do wish to make sure you know that gerbils do chew through plastic and make quick work of tubes and tunnels. Within a couple weeks there could be a hole large enough for him to get out. Please just keep an eye on him to make sure he's not chewing on it. If he is, you may want to put him in a safer cage. I've seen many gerbils chew through the Critter Trail cages and many distraught owners wondering how to find their gerbils once they have escaped. Many owners don't feel their gerbil is a chewer or that the plastic is thick enough, but never underestimate the power of their determination and jaws. Many will chew through it, it simply ends up being a matter of when. Then again, some are fine, but in my own experience with gerbil parents, their gerbils all found a way out. My own two included (though I had been watching and as soon as I found the possibility of them making it out, they were immediately switched to a safer cage).

Q: What are the advantages of using plastic tubes in the electronics industry?: There are several advantages of using plastic tubes in the electronics industry. Firstly, plastic tubes provide excellent insulation properties, protecting the electrical components from external factors such as moisture and dust. This insulation helps to prevent short circuits and electrical failures, ensuring the longevity and reliability of the electronic devices. Secondly, plastic tubes are lightweight and flexible, making them easy to install and manipulate during the manufacturing process. Additionally, plastic tubes are cost-effective compared to other materials, making them an economical choice for mass production. Lastly, plastic tubes can be easily customized in terms of size, shape, and color, allowing for efficient organization and identification of different cables and wires within electronic systems. Overall, the use of plastic tubes in the electronics industry offers enhanced protection, convenience, and cost-efficiency.

Q: Are plastic tubes BPA-free?: Yes, plastic tubes can be BPA-free. BPA (bisphenol A) is a chemical commonly found in certain types of plastic that can leach into food or beverages. However, many manufacturers now produce plastic tubes using BPA-free materials, ensuring they are safe for use. It is always recommended to check the packaging or inquire with the manufacturer to confirm if a specific plastic tube is BPA-free.
