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 ceramic tubes in terms of weight?: Plastic tubes are generally lighter in weight compared to ceramic tubes.

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: It's kind of like a slushy. What's it called?: If we are thinking of the same product, it isn't actually a candy. It is called a Kool pop, and is closer to the pop sicle family of frozen treats.

Q: i want to buy it: It depends on the size and the brand. They can cost anywhere from 4-25 dollars.

Q: Are plastic tubes safe for food and beverage applications?: Yes, plastic tubes can be safe for food and beverage applications. However, it is essential to use food-grade plastic materials that are approved by regulatory bodies and meet specific safety standards. It is also crucial to ensure proper cleaning and maintenance to avoid any potential contamination.

Q: I was changing my engine oil via the dipstick tube and a special suction device that pumps the old oil out of the sump to be replaced with fresh oil. Unfortunately, i had to patch up a hole in the tube on the suction device with parcel tape/sellotape wrapped around and a small piece of tape (around 2x2 square) fell into the engine dipstick tube and appears to have slid down into the oil sump.Will the oil filter make any difference in keeping melted plastic out of the engine? Am i best calling up the manufacturer, not the dealer as i don't want them to know about my error. The engine still runs and i have driven 20 miles so far with no problems. 2009 year Citroen C1Thanks: if the peice of tape gets 'sucked onto the oil pump pick up screen it will stop lubrication of the whole engine and engine failure. I would get it out asap and do the next oil change in the proper manner.

Q: Sooo...i'm having some trouble here. I have about 3000 feet of plastic tubing (that looks a lot like the rubber tubing you'd see in a lab). Thats all i know about it.....and i need to find the right sized pump to get 2 gpm of water. Its 1/2 inch diameter tubing. Any sort of estimate would be nice.......trying to make sure i don't get a pump to weak. But don't wanna go to overboard (limited funds). thanks: I suppose that tubing will be used horizontal at all times during the course of operation with out any fittings. If yes then get pressure at the outlet end by Q (Flow)= Pressure x Area (inner) Find pressure drop from any sourse ( e.g. Ask manufacturer for pressure drop per 1000 foot) Add pressure drop of entire lenght to pressure from formula. Have 20% safety factor added. In case of any fittings used add pressure drop of fittings (from Mfg.) to pressure drop of tubing, if height changes; for every 2.31 feet have a loss of 1 PSI added to original loss of tubing before adding safety factor. Hope it help

Q: Can plastic tubes be used for marine applications?: Yes, plastic tubes can be used for marine applications. They are often used in various marine systems such as plumbing, water intake and discharge, and fuel lines due to their resistance to corrosion and ability to withstand harsh marine environments.

Q: Can plastic tubes be used for personal care products?: Yes, plastic tubes can be used for personal care products. They are commonly used for packaging and dispensing various personal care items such as toothpaste, lotions, creams, gels, and serums. Plastic tubes are lightweight, durable, and offer convenient and hygienic application of these products.

Q: What are the common applications of plastic tubes?: Plastic tubes have a wide range of common applications, including packaging for products such as cosmetics, pharmaceuticals, and food items.
