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: Hot melt connection method of PE-RT plastic pipe and the matters needing attention: When welding elbow or three way, according to the design drawing requirements, should pay attention to the direction, in the pipe fittings and pipe in the straight direction, with auxiliary sign mark its position;

Q: How do you store plastic tubes?: Plastic tubes can be stored by organizing them in a designated container or drawer to keep them neatly arranged. It is also helpful to label or categorize them based on size, type, or purpose for easier access and identification.

Q: I still have the fork tubes mounted to the bike. I have removed the cap, spacer tube, washer, spring, damper bolt (from the bottom of the tube) and removed the damper and short spring. I have pried the dust cap (rubber seal) and slid it all the way up. There is a piece of plastic? or nylon? that is blocking the circlip(I assume). I do not have a manual for this bike but I can not get one for a few days, so the help would be great!!: Just pry the plastic ring up (nothing is holding it). Perhaps it's stuck to the foam ring underneath it. After you remove the circlip, the the fork tube and lower will have to be pulled apart. The fork seal is in very tight. Hold the tube in one hand and the lower in the other hand. Push the forks together. Yank them apart with force (a bushing inside of the forks will hit against the seal like a slide hammer). They won't come apart in one pull. Push them - in - OUT -in - OUT - in - OUT

Q: Do plastic tubes have any health risks?: Yes, plastic tubes can pose health risks depending on the type of plastic used and the intended use of the tube. Some plastics contain harmful chemicals such as BPA (bisphenol A) or phthalates, which can leach into the contents of the tube and potentially cause health issues when ingested or absorbed by the body. Additionally, plastic tubes used in medical procedures or surgeries can carry the risk of infection if not properly sterilized or if they are made from low-quality materials. It is important to consider the specific plastic composition and usage guidelines when assessing the potential health risks of plastic tubes.

Q: Can plastic tubes be used for water supply systems?: Yes, plastic tubes can be used for water supply systems. Plastic pipes, such as PVC (polyvinyl chloride) and PEX (cross-linked polyethylene), are commonly used in residential and commercial water supply systems due to their durability, flexibility, and resistance to corrosion. They are lightweight, easy to install, and can handle high-pressure water flows efficiently. Additionally, plastic pipes are less prone to leaks and can last for many years, making them a popular choice for water supply networks.

Q: where is the best place to go to buy a plastic tube (the kind you store items in?: try ace or i know true value hardeware stores carry them we sell them on mothly specials all the time and they come in a number of sizes

Q: Two identical bar magnets are dropped at the same time from the same height down tubes of the same length. Magnet A is dropped down an aluminum tube while magnet B is dropped down a plastic (non-conducting) tube. Which magnet reaches the bottom of the tubes first? Magnet A will not fall through a conducting tube. Both arrive at the same time. Magnet A. Magnet B. The answer depends on the permeability of the plastic in the plastic tube.: No madam same twins such as you could no longer have comparable face and top so whats the component u opt to grow to be same twins do no longer hesitate bypass forward which contain your analyze in genetics i informed u do no longer produce a clone thats very final answer out of your bestest pal so what u call.

Q: How do you put the plastic pick up tube on to the brass pick up tube on a briggs and straton carburetor?: You need the proper size tubing, and it just slides over, and a clamp holds it in place.

Q: Are plastic tubes suitable for use in extreme temperatures?: No, plastic tubes are not suitable for use in extreme temperatures as they can melt or become brittle, leading to potential failure or damage.

Q: What is the maximum length of plastic tubes available?: The maximum length of plastic tubes available can vary depending on the manufacturer and the specific type of plastic tube. However, in general, plastic tubes can be found in lengths ranging from a few inches to several feet.
