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:What's the meaning of the laying of brick and concrete structures with concealed pipes?: Line pipe laying:The wires are laid in bricks or concrete. There are two ways:Insert the wire tube and the bottom box before pouring;After the end of the masonry, slotted into the wire pipe and the bottom box, and then fill the groove.

Q:Can plastic tubes be used for paint or adhesive packaging?: Yes, plastic tubes can be used for paint or adhesive packaging. They are durable, versatile, and provide easy dispensing of the product. Additionally, plastic tubes are lightweight, cost-effective, and allow for precise control of the amount of paint or adhesive being used.

Q:Can a plastic pipe be evacuated into a vacuum?: Yes, the polypropylene material can be made into a vacuum

Q:ive heard stories about syrian hamsters getting stuck in tubes.: wellll keep in shape and it will be fine

Q:What types of closures are available for plastic tubes?: There are several types of closures available for plastic tubes, including screw caps, flip-top caps, snap-on caps, pump dispensers, and flip-top snap caps.

Q:does it matter where you pur the fluid and how much should be poured in my vanhave a radiator caop and then like a long plastic tube that goes down to the engine and says coolant on it...where do i pour the antifreeze??: Fill-up the plastic container The plastic container that connects to your radiator is the extra fluid. The level of fluid in that container will rise and lower as the heat of the fluid changes, but should be at the full mark when your car has not been running. If you are loosing fluid due to a leak and it gets too low fill it up with water. Radiator Coolant is used particularly in places were its cold, because its much harder to freeze. But if you run out, your car could over heat.

Q:Am I even safe to drive to the mechanic or should I just two it? Holy crap, that could have been there for months for all I know since I last checked.: That's your air intake boot that routes air from your air cleaner to your intake. Since it's cracked after the air filter, any crap (leaves/dust/etc) can get sucked directly into your engine. It's a cheap part to replace.

Q:So, I went to the dentist today to get my teeth checked out. The oral surgeon said I need two teeth pulled out, but I need to be knocked out cuz it's so bad. He said the way he's gonna do it, is by putting an IV in (scared of needles:( ) and then I asked my mom and she said they were gonna take the needle out and keep a little tube in there? I'm really confused about this. Help please.: And they do this procedure SEVERAL TIMES A DAY!!!!!!! YOU'LL BE FINE!!!!!!!

Q:Do plastic tubes have any limitations in terms of light transmission?: Yes, plastic tubes can have limitations in terms of light transmission. The type of plastic used, its thickness, and the presence of additives or impurities can affect the amount of light that can pass through the tube. Some plastics may have higher light absorption or scattering properties, which can reduce the amount of light transmitted through the tube. Additionally, longer or curved plastic tubes may cause further light loss due to internal reflection or refraction.

Q:what are the plastic or aluminum tubes called on pontoons?: I always called ours pontoon tubes or floatation tubes.
