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 are plastic tubes sterilized?: Plastic tubes are typically sterilized using various methods such as autoclaving, ethylene oxide gas sterilization, gamma irradiation, or chemical sterilization. These processes help eliminate any potential microorganisms or contaminants present on the tubes, ensuring their safety for medical or laboratory use.

Q:Hello, I'm making my own skin hair care products and my question is, what store other than Micheals can I purchase plastic containers and tubes to put my product in? I'm not talking about food items either I'm talking about Jars to store shea cocoa butter in it. Also, I want to be able to provide my own wrapper? Like what can I do to make my own wrapper sticker ... basically advertising my own product line's name and whichever design I'd like on it?? Thanks in advance :): You can purchase standard plastic jars (10ml-500ml) from the UK specialist Manuplastics Ltd.

Q:EXACTLY WHERE AT THE MOUTH OF A PLASTIC TUBE DOES THE PRESSURE NODE FORM? (Dealing with standing waves in air)?: Level with the open end. Pressure nodes form where there are displacement antinodes and displacement nodes form where there are pressure antinodes If you look at the diagram, this will be clear.

Q:i connected a plastic tube about 7 or 8 inchs long onto a butane can im wondering if when i push down on the can and put a match near it can the fire go back into the can and make the can explode: Sure can, even if you've posted this in the wrong category. Funny thing about fire... it likes to burn as long as possible so if the flame makes it's way into the tube... you should duck. Don't be foolish, keep your hands, fingers, eyebrows, etc and quit playing with fire.

Q:Can plastic tubes be used for water transportation?: Yes, plastic tubes can be used for water transportation. They are commonly used for various applications such as irrigation systems, plumbing, and even in some industries for transferring water or other fluids from one location to another. Plastic tubes are lightweight, durable, and resistant to corrosion, making them suitable for water transportation purposes.

Q:Rescue fish, currently in temporay home 20 gal 70' filtered oxygenated tank until I can get another tommorow. But he looks stressed, I think he needs a place to hide for the night, and the PVC I have at the moment is too light to sink. I found the plastic in the basement of the older home we live in, good size for him, but I am worried that plastic of an uncertain age might give off some kind of toxin/poison. Can anybody help? Suggestions for alternatives welcome...: Nope. It's safe. PVC is used for tube anemones commonly.

Q:Do plastic tubes have any limitations in terms of moisture resistance?: Yes, plastic tubes do have limitations in terms of moisture resistance. While some plastic materials used in making tubes may offer good moisture resistance, others may be more susceptible to moisture absorption or degradation over time. Factors such as the type of plastic, thickness, and manufacturing processes can influence the level of moisture resistance. It is important to consider these limitations when choosing plastic tubes for applications where moisture resistance is critical.

Q:Hi all. My mom gave me an old lamp, not old cool or worth something just old. I think the proper term would be free standing. It has four bulbs, three surround the center bulb under a lamp shade. I'm trying to update the thing a little... painted the base and stand, got a new lamp shade, put in energey efficent bulbs.. the only part that is bugging me are these three plastic peices whose purpose is to cover the wires running to the bulbs above. One of them is cracked so i want to replace all three. Hoping someone can tell me the name of what I need before I gassed it to the closest home depot/lowes to return empty handed.Thanks for you help.: Take the piece with you to the closest of these 2 stores and look in the plumbing isle for PVC pipe the same size. If the new pipe has writing on it you need to get off use a scotch brite pad.

Q:Can plastic tubes be used for fishing rod blanks?: Yes, plastic tubes can be used for fishing rod blanks. However, they are not commonly used due to their lack of durability and flexibility compared to traditional materials like graphite or fiberglass.

Q:Sticks into her throat? What is that? what health problem does she have?: That tube Is so she can breath she has had a tracheotomy.
