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: How do plastic tubes compare to ABS tubes in terms of impact resistance?: Plastic tubes generally have lower impact resistance compared to ABS tubes. ABS (Acrylonitrile Butadiene Styrene) is known for its exceptional impact resistance, making it a preferred choice in applications where durability and resistance to impacts are crucial.

Q: What are the different types of plastic tubes available?: There are several different types of plastic tubes available, including PVC (polyvinyl chloride) tubes, PE (polyethylene) tubes, PP (polypropylene) tubes, and PTFE (polytetrafluoroethylene) tubes. Each type has its own unique properties and is suitable for specific applications.

Q: What is the name of the popsicle that comes in a plastic tube and breaks in half?: Flav-or-ice or Pop Ice. Both are the same thing, just different brands.

Q: Can plastic tubes be used for fuel lines?: Yes, plastic tubes can be used for fuel lines.

Q: Are plastic tubes resistant to impact from freezing temperatures?: Yes, plastic tubes are generally resistant to impact from freezing temperatures.

Q: Wondering if there is any health risk associated with putting pieces of copper pipe, plastic PVC (?) pipe, or garden hose pieces into a campfire? I have been to campfires where these things have been put into the fire, and it does make the fire turn all kinds of colors. Just wondering if it's safe to sit around the burning campfire with these things added....: The fine soot that the pvc gives off will enter your lungs and deposit HCL there. If you get too big a snoot full, you end up with a pneumonia like sickness and you can imitate people who have been in house fires where the furnature burns. They come out with black snot and are really sick the next day. Copper pipe shouldn't get you too bad but locally a woman whose husband burned wires to get copper scrap almost lost a leg to an infection that was a reaction site to copper poisoning. Stay upwind!

Q: Do plastic tubes have any odor or taste?: Yes, plastic tubes can have a slight odor or taste, especially if they are made from low-quality plastics or have been exposed to certain chemicals. However, high-quality plastic tubes that are specifically designed for food or medical use are usually odorless and tasteless.

Q: can you use copper piping to fire firework rockets instead of plastic tubes ?: Yes, it is better because if the tube explodes, x-rays cannot find plastic in your body but copper will show up.

Q: What are the common diameters of plastic tubes used for irrigation in agriculture?: The common diameters of plastic tubes used for irrigation in agriculture range from 0.5 inches (12.7mm) to 1 inch (25.4mm).

Q: What are the advantages of using plastic tubes in the agricultural sector?: The advantages of using plastic tubes in the agricultural sector include their durability, flexibility, and resistance to corrosion and chemical degradation. Plastic tubes are lightweight and easy to install, reducing labor costs. They provide a cost-effective solution for irrigation systems, allowing for efficient water distribution and minimizing water wastage. Plastic tubes also offer protection against UV rays, preventing damage and extending their lifespan. Additionally, their smooth interior surface reduces friction, leading to improved flow rates and energy savings.
