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: An air core is no core except air.: Cute, but I saw the punch line back with the first bird.

Q: How do you clean clogged plastic tubes?: To clean clogged plastic tubes, you can try a few methods. First, try using a plunger to create pressure and dislodge the clog. If that doesn't work, you can use a mixture of hot water and dish soap to break down any grease or grime causing the clog. Alternatively, you can try using a pipe snake or a wire hanger bent into a hook shape to physically remove the blockage.

Q: Can plastic tubes be easily cleaned or sterilized?: Yes, plastic tubes can be easily cleaned and sterilized. They can be washed with soap and warm water, and then sterilized using various methods such as autoclaving, steam sterilization, or chemical disinfection.

Q: I'm going to The Tubes concert this Saturday in Niagara Falls NY..I'm really looking forward to seeing them, especially Fee Waybill. Your thoughts/memories/opinions.Members- Fee WaybillRoger SteenDavid MeddRick AndersonPrairie Prince Former members- Bill Sputnik SpoonerGary CambraRe StylesMichele Rundgren (nee Gray)Mingo LewisVince WelnickMichael CottenDavid Killingsworth: I do, I went to many of their entertaining concerts in the late 70's and 80's. The Tubes' live shows were rife with allusions to mainstream film (Dr. Strangelove, Rollerball, Saturday Night Fever, Grease), then-forgotten B-movies (Wild Women of Wongo, Attack of the 50 Foot Woman), music (Tom Jones, punk rock, a medley of Nelson Riddle television themes), contemporary pop culture (Patty Hearst, the Viking program), television (Let's Make a Deal, Fernwood 2Nite, the anime Raideen), and literature (Nelson Algren's A Walk on the Wild Side), presaging the subcultural reverence and over-the-top theatricality of later groups like The World/Inferno Friendship Society. These shows were expensive to produce, however, and while they earned the band a reputation for being one of the most entertaining live acts of all time. You have inspired me to pull out my Tubes collections! Have Fun!

Q: Regarding the cigars. The following is for the humidity conditions. It is now 4:50 pm here, I am going to a party tomorrow at 4:00 pm. So 24 hours time. I live in South Africa and its winter here. I bought Romeo y Julieta cigars (Romeo No3 and 2) and a Blackstone Cherry (not a cigarillo). I don't have a humidor. But I looked in the tubes (Romeo Julieta tubes- they are metal tubes) of the Julietas and they have a wood layer around the inside of the tube. Will these cigars be fine in these conditions for 24 hours in their tubes? The Blackstone is in a plastic tube with no wood. Just plastic. Must I leave the cigars in their tubes in a Ziplock bag? And I have no waterpouches humidification pouches. I read on Cigars for less that tubes can preserve them for a long time. Oh, and I have air-conditioning in my room. But will the cupboard in my room work? I usually set the aircon between 18-21* Celsius. I can put the cigars somewhere else if it is better.: I would keep in a desk drawer lying on their sides wrapped in their tubes.

Q: The iron pipe is rusty. How can the plastic pipe be connected?: The use of water leakage tape wrapped around the top of the external thread, and tighten the wire, because the plastic pipe, not too hard, so as to avoid pipeline crack.

Q: What are the different printing options for plastic tubes?: The different printing options for plastic tubes include silk screen printing, pad printing, digital printing, and offset printing.

Q: How does transferring of liquid in a container to an empty container using a plastic tube works?: A siphon hose used to draw gas from a car's fuel tank is one example and is a very simple pump. Sucking on one end of the hose creates an area of low pressure compared to the relatively high-pressure area of the gas tank. This low pressure versus a higher pressure is key to the transfer. Eventually, the gasoline will come out of the low-pressure end of the hose and the process feeds on itself so to speak via momentum, and the fluid continues to transfer.

Q: OK I am trying to make one of those soda drinking hats (because I have all of this spare clear plastic tubing from Menards from another project, and I couldn't think of anything else to do with it). When drinking out of it, it gives that plastic-like taste which I hope will go away over time. Anyway is this bad for me because I don't know if there is a different cleaner tubing that the real hats use and if it is safe to drink from their tubes. Should I just buy one of the hats off OKorder or just make my own... I don't want to poison myself or anything.: what kind of tubing was it? was it sitting in the garage for months? the plastic taste isnt bad, but if it was sitting in your garage for months, you might wanna run soappy water throught it a few times then run clean water throught it for a few mins....just to be safe

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 are lightweight and easy to handle, making them convenient for transportation and installation. Secondly, plastic tubes offer good insulation properties, protecting delicate electronic components from electrical interference and damage. Additionally, plastic tubes are resistant to corrosion and chemicals, ensuring the longevity and durability of the electronic devices. Lastly, plastic tubes can be easily customized and molded into different shapes and sizes, allowing for flexibility in design and optimizing space utilization in electronic systems.
