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: Like in the piercing shops, they pierce it with the needle and the plastic tube thingy... Then they take the needle out and leave the hollow plastic tube in the put the lip ring..,... I was wondering where can I buy that?: The needles are generally soldered by the piercer and the tube is special order. There is a reason that you have to be licensed to be a piercer you know, things like infection, sterilization, and laws

Q: How to remove dirt on the inner wall of plastic pipe?: With a wire wrapped in absorbent cotton, soaked in water, put into the plastic pipe, wet the pipe wall, pull out the wire, stained with cleaning materials, second times into the plastic pipe, wipe back and forth, and then washed with water.

Q: Are plastic tubes transparent or opaque?: Plastic tubes can be transparent or opaque, depending on the type of plastic used and its color.

Q: If you buy them in bulk from the mint, what do they come in?: 2006 American Buffalo Gold Proof One Ounce Coin Gold buffalo $800.00 coin? Individual in a case with letter of authenticity. each coin enclosed in hard round plastic and place in a blue case.. very nice and very beautifully.... The American Buffalo Gold Proof Coins are collector versions of the official United States Mint American Buffalo Gold Bullion Coins and are available in limited mintages. The designs are based on the original 1913, Type I Buffalo nickel, as designed by James Earle Fraser. very very sharp proof coin.. This coin is going to be a winner 20 years from now in the market place among collectors.. us mint link and picture catalog.usmint /webapp/wcs/sto...

Q: What are the different material options for plastic tubes?: There are several different material options for plastic tubes, including polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET). Each material has its own unique characteristics and is suitable for different applications based on factors like strength, flexibility, chemical resistance, and temperature tolerance.

Q: How are plastic tubes filled with liquids or semi-liquids?: Plastic tubes are typically filled with liquids or semi-liquids through a process called filling. This involves using specialized machinery and equipment to accurately dispense the desired substance into the tubes. The filling process may vary depending on the viscosity and specific requirements of the product being filled. It often involves using a combination of pumps, nozzles, and controlled pressure to ensure precise and consistent filling.

Q: Hey y'all, I've seen a few people at my hospital with charms made from medication vials and IV tubing hanging on their stethoscopes... Does anyone know how to make these??PS: I'm well aware of infection control issues associated with dangling things... I'm looking to make keychains like these.: if you combine tahese sources, you mightlearn what you need. Plastic tube jewelry and some med charms?

Q: For some tuning fork frequencies is it possible to hear resonance at more than one length of the plastic tube? Why?: Because the tube might be long enough to reflect the third harmonic( if it is a tube closed at one end ). It is easier to find the 2nd resonance with the higher pitched tuning forks.

Q: What kind of pipe material does the building PPR pipe belong to? Is it a plastic tube or a composite pipe?: Plastic pipe.PPR tubes are also called random copolymerized polypropylene pipes. It is a new plastic pipe product developed and applied in Europe in the early 90s. The utility model has the advantages of high strength, good shock resistance, long term creep resistance, excellent chemical property corrosion resistance (not soluble at any known solvent at ordinary temperature), etc..

Q: I adopted two new gerbils yesterday, and they are pretty well adapted so far. They live in an aquarium with a connected bin which is much larger and hold many things to chew on tons of bedding to dig in. These are two of the things they like best. Unfortunately, despite having tons of things to chew on including paper towels, wood blocks (which they don't find the least bit interesting), and cardboard (which is their favorite thing to chew on), one of my gerbils still resorts to chewing on the inside of the plastic tubes connecting the bin to the aquarium. Any ideas on how to stop it? I can't connect them any other way, and the only way they would get to the bin other than the tubes, would be for me to manually place them there (they don't trust me completely yet, but they are curious and have come up and sniffed, walked on my hand). Trying to catch them makes feel like a I'm stressing them out, and making them scared of me. What should I do?: First of all, aspen isn't good for rodent. Try using Carefresh or atleast pine. U probably think they're eating it but they aren't. They';re probably just putting it inside in their pouch to bring it to their nest or something. My gerbil does that too. So don't worry about it. Maybe you can put more bedding inside thegerbil's nest to save up some work for the gerbil. =)
