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: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:How do plastic tubes perform in high-altitude environments?: Plastic tubes generally perform well in high-altitude environments as they are lightweight, durable, and resistant to extreme temperatures. However, it is important to choose tubes made from materials that are specifically designed to withstand the conditions of high-altitude environments, as some plastics may become brittle or degrade under low atmospheric pressure.

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?: Well done for adopting a gerbil! i advise you to buy a few tubes on OKorder or the petshop and put it in the aquarium or connected bin so he can chew that one. He might be a bit bored . Buy him or make him a few toys to play with. Good Luck !

Q:What flange plate is used to connect the plastic pipe to the flange valve?: Flange flange and pipe connection requirements are the same, only the welding materials for plastic welding, welding material should be the same as the parent material.

Q:Can plastic tubes be used for household products?: Yes, plastic tubes can be used for a variety of household products. They are commonly used for packaging items such as toothpaste, lotions, creams, and various types of liquids. They are lightweight, durable, and provide convenience for dispensing and storing household products.

Q:How are plastic tubes cut to specific lengths?: Plastic tubes are cut to specific lengths using various methods such as sawing, scoring and snapping, or using a tube cutter tool.

Q:I have a big section of vinyl/plastic tubing does anyone have any ideas for what i could make out of it? Thanks in advance!: You can use it as a storm drainage from your house to the main sewer line, you can use it too as false column in your house as additional decoration, can be use as a form of a circular post, can be use as backyard bench.

Q:Are plastic tubes resistant to mold or mildew?: Yes, plastic tubes are generally resistant to mold or mildew due to their non-porous nature, making them less susceptible to moisture and organic growth.

Q:Can plastic tubes be used for food and beverage applications?: Yes, plastic tubes can be used for food and beverage applications.

Q:It is also Nat'l Buy a Musical Instrument Day!!: Interesting question to which I can't seem to find a definitive answer here on the net. I do hope that you pick a BA and then let the rest of know why toothpaste companies made the switch. I'm assuming it was a cost saving measure. So what musical instrument are you going to buy? <g EDIT: I REMEMBER when toothpaste came in metal tubes and they never got holes in them just weird creases that made it diffcult at times to squeeze out all the toothpaste.
