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 industries use plastic tubes?: Several industries utilize plastic tubes, including the medical and pharmaceutical industry for applications like IV tubing and medical devices. The construction industry uses plastic tubes for plumbing and electrical wiring. Additionally, the packaging industry utilizes plastic tubes for various purposes like cosmetic packaging, food containers, and industrial packaging.

Q:Can mercury be stored in a hard plastic test tube?: be aware that temperature plays a crucial factor with mercury, putting a lot of mercury into a test tube will be a bad idea if it's possible that the temperature will fluctuate. Storing it inside the fridge would be a good idea or storing a small amount should be fine though

Q:Can plastic tubes be used for sewer lines?: Yes, plastic tubes can be used for sewer lines. Plastic pipes, such as PVC (polyvinyl chloride) or HDPE (high-density polyethylene), are commonly used in modern sewer systems due to their durability, resistance to corrosion, and ease of installation. Plastic tubes offer a cost-effective and efficient solution for sewer line applications.

Q:What is the maximum temperature plastic tubes can withstand?: The maximum temperature that plastic tubes can withstand varies depending on the type of plastic used. Generally, most plastic tubes can withstand temperatures up to 140-160 degrees Fahrenheit (60-70 degrees Celsius). However, some specialized plastic tubes, such as those made from heat-resistant materials like PTFE or PEEK, can withstand higher temperatures ranging from 300 to 500 degrees Fahrenheit (150 to 260 degrees Celsius). It is important to consult the specific technical specifications or manufacturer guidelines for the plastic tube in question to determine its maximum temperature resistance.

Q:How do plastic tubes compare to polyurethane tubes in terms of flexibility?: Polyurethane tubes are generally more flexible than plastic tubes.

Q:What are the different ways to cut plastic tubes?: There are several ways to cut plastic tubes. Some common methods include using a sharp knife or scissors, using a hacksaw or a fine-toothed saw, using a tube cutter specifically designed for plastic, or using a heat tool to melt and separate the tube. The method chosen depends on the specific type and thickness of the plastic tube and the desired precision of the cut.

Q:Is the water pipe made of stainless steel or plastic pipe?: In Germany, eighty percent of households in the United States have used stainless steel pipes. There are also many excellent stainless steel tube brands in China, such as the stainless steel tube produced in a century, which belong to the food grade health pipe.

Q:What are the different end closures available for plastic tubes?: There are several different end closures available for plastic tubes, including screw caps, snap-on caps, flip-top caps, pump dispensers, dropper tips, and squeeze dispensers.

Q:How is 20 silver dollars inserted into plastic tube?: Home All Categories Computers Internet Internet YouTube ??

Q:We are interested in tubing on a creek with class I to II rapids, so we want something durable to hold up going over rocky patches. Are the 3-layer PVC plastic tubes sold for river tubing and towing behind boats strong enough for that? Or would a black rubber tire from a semi-truck be better?: definitely the rubber ones the plastic ones will scratch your inner arm cause the seem is right in the middle
