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 promotional products?: Yes, plastic tubes can be used for promotional products. They are versatile, customizable, and can be easily branded with company logos or messages. Plastic tubes can be used to package and display various promotional items such as pens, keychains, USB drives, or small merchandise. They provide a cost-effective and visually appealing way to promote businesses and their products or services.

Q: Are plastic tubes suitable for use in the water treatment industry?: Yes, plastic tubes are suitable for use in the water treatment industry. Plastic tubes are often made from materials such as PVC or polyethylene, which are resistant to corrosion, chemicals, and UV degradation. These tubes can effectively transport water and various chemicals used in the treatment process without contaminating the water supply. Additionally, plastic tubes are lightweight, durable, and cost-effective, making them a popular choice in the water treatment industry.

Q: Those ices that come in a plastic tube.: about 150 calories

Q: Can plastic tubes be used for food packaging?: Yes, plastic tubes can be used for food packaging.

Q: Are plastic tubes suitable for electrical conduit?: Yes, plastic tubes can be suitable for electrical conduit depending on the specific requirements of the installation. Plastic conduits are lightweight, easy to install, and resistant to corrosion, making them a cost-effective choice for non-metallic conduit applications. However, it is important to ensure that the plastic conduit meets the necessary electrical code requirements for the intended use.

Q: Can plastic tubes be used for food and beverage applications?: Yes, plastic tubes can be used for food and beverage applications. They are commonly used for packaging and transporting various food and beverage products such as sauces, juices, and condiments. Plastic tubes offer advantages such as flexibility, durability, and resistance to chemicals, making them suitable for safely containing and dispensing food and beverages.

Q: Something that can coil up.: Any good hardware store. They have flexible plastic tubing displays in all different diameters.

Q: What are the different types of plastic tubes?: There are several different types of plastic tubes, including PVC tubes, polyethylene tubes, polycarbonate tubes, polypropylene tubes, and acrylic tubes. Each type has its own unique properties and is used for various applications such as plumbing, electrical conduits, packaging, and scientific experiments.

Q: Suppose that you have an acrylic box containing water inside, as well as a submersible water pump and tubing. Also assume that you have a viable source of energy to turn the pump on.: If it's a compression becoming it's going to have threads and a nut on it. When you purchased it there must had been a unfastened brass ferrule in below the nut. You slip the nut over the copper tubing, slide on the brass ferrule, after which tighten down the nut. Two words of warnings when utilizing compression fittings: fundamental!!! (1) do not overtighten the nut, and even more importantly, (2) if you start tightening the nut, you can't turn the nut the improper way (as if to loosen it) even very reasonably. ALL turning movement have got to be to tighten most effective. If you are making a mistake and even flip the wrench back 1/4 an inch which you can wreck the compression of the ferrule and the fitting will leak and no matter how tight you tighten it after that it is going to leak. At that factor you can have got to either reduce out the pipe or or else get rid of it and over.

Q: How do plastic tubes compare to polycarbonate tubes in terms of impact resistance?: Polycarbonate tubes have higher impact resistance compared to plastic tubes.
