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 pool equipment?: Yes, plastic tubes can be used for pool equipment. They are commonly used for applications such as pool filters, pumps, and plumbing systems due to their durability, resistance to corrosion, and ability to withstand water pressure.

Q: Are plastic tubes suitable for display racks?: Plastic tubes can be suitable for display racks depending on the specific needs and requirements of the display. They are lightweight, durable, and can be easily customized to fit various sizes and shapes. However, the suitability ultimately depends on factors such as the weight and size of the items to be displayed, the desired aesthetic appeal, and the overall functionality of the display rack.

Q: How to mend a hole in a plastic pipe?: First wash and dry the tear, then find a quick plastic, point it at the plastic pipe with the fire, drop the melted plastic in the damaged area, and then flatten it.

Q: Are plastic tubes suitable for industrial automation?: Yes, plastic tubes are suitable for industrial automation. Plastic tubes offer numerous benefits such as being lightweight, flexible, and resistant to corrosion, chemicals, and high temperatures. They are also cost-effective and can be easily integrated into automated systems. Additionally, plastic tubes offer excellent performance in various applications like pneumatic and hydraulic systems, conveying fluids, and protecting wires and cables.

Q: hi I don't really know a lot about plumbing but today my bathroom sink was clogged so I took the j looking pipe apart and when I did a plastic tube looking thing fell out from the first pipe and when I tried to put everything back together that thing wouldn't stay. help?: the word here that is of importance iseverything. Obviously the plastic tube is an integral part of the assembly. It is not there to look pretty. So, it must be a collar (like a choker) that fits very tightly on one piece and under another. The screw nut then squeezes the outer one. It is like taking your hand and putting it in a glove and then putting that gloved hand in a woodchipper

Q: A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. It can then be squirted over the meat.Using 1.013e+05 Pa for the atmospheric pressure and 1100 kg/m3 for the density of the sauce, find the absolute pressure in the bulb when the distance h is each of the following.(c) h = 0.140 m Pa=?(d) h = 1.10 10-1 m Pa=?: This Site Might Help You.

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: Can plastic tubes be used for greenhouse construction?: Yes, plastic tubes can be used for greenhouse construction. They are often used as a cost-effective alternative to traditional materials such as metal or wood. Plastic tubes are lightweight, easy to handle, and resistant to weather and corrosion, making them suitable for greenhouse structures. Additionally, their flexibility allows for creative designs and easy installation.

Q: What is the difference between rigid and flexible plastic tubes?: Rigid plastic tubes are firm and inflexible, maintaining their shape without bending or distorting easily. On the other hand, flexible plastic tubes are pliable and can be bent or twisted without breaking, allowing for more versatility in various applications.

Q: How do you prevent plastic tubes from warping?: To prevent plastic tubes from warping, it is important to store them in a cool and dry environment, away from direct sunlight or heat sources. Additionally, avoid placing heavy objects on top of the tubes, as it can cause deformation. Choosing tubes made of high-quality, durable plastic materials and handling them with care during transportation and usage can also help prevent warping.
