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's the diameter of the white plastic tube in the kitchen, about 10cm? What should I do if the water leaks?: Electrode welding: buy several PVC welding electrodes to the building materials shop or hardware city, and weld the welding rod to dew point with hot blast welding torch.The above two methods must first wipe the dew point, no water, and within 12 hours after the repair and repair, the water pipe shall not be used.

Q: My son had ear tubes inserted about two years ago. I have always used drops in his ears and cleaned them, etc. Sometimes I would look in them with a flashlight to make sure they were ok and not leaking, (When you get an ear infection with tubes, your ears drain some). Today I was doing just that with a flashlight and I actually saw the tubes in both ears..I never noticed this before and I am a VERY observant mother. Could this mean they are getting loose or close to falling out?? Or is it just that I never noticed before. I did try to see them when he first got the tubes, but I never could. Today, out of nowhere I could see these white plastic tubes?? He has been very cranky and irritable, but can't seem to pinpoint where he isn't feeling well. Does losing your tubes (if that is what it is) cause some discomfort?? I imagine it would...anything involving your ears doesn't feel very good. Any medical professionals or experienced parents with any good thoughts???: i strongly suggest to bring him to his ENT doctor. have it checked.. you can only visualize it through an otoscope and not a flashlight. if you can see it something might be wrong. so have it checked now

Q: What is the minimum length of plastic tubes?: The minimum length of plastic tubes can vary depending on the specific application and requirements. It can range from a few centimeters to several meters or more, depending on the intended use and manufacturing capabilities.

Q: Can plastic tubes be used for electrical wiring protection?: Yes, plastic tubes can be used for electrical wiring protection. They provide insulation and help prevent damage to the wires from moisture, chemicals, and physical impact.

Q: There was no needle inside the tube... do you think my dad was using drugs??: Hard to say. He could have been using it for something else too. /could have the liquid inside analyzed, but I agree talk to him, tell him what you found and voice your concern. What is the worse that could happen?

Q: How can I get the feed to keep going down into the cups? The birds peck it out, but it never goes back into the feeder cup. I have to go out and use a wire hook i made up to get it back in the cups so the birds can reach it again. It is a 4 port, about 18 inches tall, the cups are closer to the bottom, so yo'd think the weight would push the seed down into the cups. Very frustrating. It is a plastic tube maybe 1.5 inches wide, and I use black oil sunflower seed (not the shelled kind): Yeah, get seed mix, not 100% sunflowers. And my cousin did this. It has a hole for the seeds to come out, not a little slit, right? The feeders with the slits are for thistle seed, not normal seeds.

Q: I used a tube to transport diesel to another container and I was wondering if it's possible to clean the tube at all.: Yea right, so you ask it in the You Tube section,........ lol good try but a troll question.

Q: How are plastic tubes labeled with lot numbers?: Plastic tubes are typically labeled with lot numbers using various methods such as direct printing, adhesive labels, or laser engraving. The lot numbers are applied to ensure traceability and quality control, allowing manufacturers to track and monitor the tubes' production details, such as the materials used, date of manufacture, and potential defects, if any.

Q: Are plastic tubes suitable for transporting hazardous materials?: Plastic tubes are not typically suitable for transporting hazardous materials due to their potential for degradation or chemical reactions with certain substances. Instead, materials such as steel or specialized containers designed specifically for hazardous materials transport are commonly used to ensure safety and prevent any potential risks.

Q: What are the advantages of using plastic tubes in the medical packaging industry?: There are several advantages of using plastic tubes in the medical packaging industry. Firstly, plastic tubes provide excellent protection against breakage, ensuring the safe transportation of medical products. Secondly, plastic tubes are lightweight, making them cost-effective for shipping and storage purposes. Additionally, plastic tubes offer superior barrier properties, protecting the contents from moisture, gases, and light. Moreover, plastic tubes are customizable, allowing for ease of labeling and branding. Lastly, plastic tubes are recyclable, making them an environmentally friendly option for the medical packaging industry.
