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: Are plastic tubes resistant to heat?: Plastic tubes have varying degrees of heat resistance depending on the type of plastic used. Some plastics, like polypropylene and PTFE, have excellent heat resistance and can withstand high temperatures, while others, like PVC, have lower heat resistance and may deform or melt at elevated temperatures. Therefore, it is important to consider the specific type of plastic when determining its heat resistance capabilities.

Q: How do plastic tubes compare to rubber tubes in terms of elasticity?: Plastic tubes generally have lower elasticity compared to rubber tubes.

Q: There are several kinds of domestic water pipes: As a new type of water pipe material, PPR tube has the advantages of being healthy and non-toxic. It can be used either as a cold water pipe or as a heat pipe,Advantages: moderate price, stable performance, heat insulation, corrosion resistance, smooth wall, no fouling, piping system is safe and reliable, not penetration, the service life of up to 50 years.Disadvantages: but it needs special tools when connecting. The connecting surface needs heating. The heating time is too long or the socket is inserted too much, it will cause water blockage.

Q: I'm Assistant Directing a production of Hairspray! and need to find a piece of tube that a person can stand inside of for the Giant can of Ultra Clutch Hairspray. We thought to use huge cardboard tubes from Home Depot but the largest size they had was only 1' diameter. Corrugated plastic tubes wont work, it needs to be smooth like PVC or cardboard. A wood tube would be okay too: Sonotube commercial concrete forms might have something that big. You can call them toll free at 888-766-8823 and find the name of the local distributor.

Q: Are plastic tubes suitable for display stands?: Plastic tubes can be suitable for display stands, especially if they are made from durable and high-quality materials. However, the suitability ultimately depends on the specific requirements of the display, such as the weight and dimensions of the items being displayed.

Q: Hot melt connection method of PE-RT plastic pipe and the matters needing attention: When the connection is made, the pipe end without rotating is inserted into the heat sleeve to be inserted into the marked depth, and at the same time, the pipe fittings without rotating are pushed on the heating head to reach the designated mark. Heating time should meet the requirements of the above table (also according to the provisions of the manufacturer of hot melt tools);

Q: the tubes are bout 1cm ID with only about a 1mm thickness. I don't think threading them will be possible, and the seal between that has to be water tight.: I would go for a coupler on the outside of the tube, which should be stronger and won't restrict the flow. Get some 12mm ID tube from a model shop or plastic supplier. Roughen the inside of the coupler and the outside of the ends of the tube with sandpaper, apply plenty of epoxy, assemble and leave to set. You might want to improvise some kind of jig to hold the 2 tubes in-line while it sets.

Q: Can plastic tubes be used for pneumatic valves?: Yes, plastic tubes can be used for pneumatic valves. Plastic tubes are commonly used in pneumatic systems as they offer various advantages such as being lightweight, flexible, and resistant to corrosion. Additionally, plastic tubes are less expensive compared to metal tubes, making them a popular choice for pneumatic applications.

Q: Can plastic tubes be used for packaging food products?: Yes, plastic tubes can be used for packaging food products. They are commonly used for products like sauces, condiments, and pastes. The plastic used for these tubes is typically food-grade and meets safety regulations. Plastic tubes offer convenience, easy dispensing, and can be sealed to maintain product freshness.

Q: Can plastic tubes be used for irrigation systems in agriculture?: Yes, plastic tubes can be used for irrigation systems in agriculture. They are commonly employed as an affordable and durable option for delivering water to crops efficiently. Plastic tubes are lightweight, easy to install, and resistant to corrosion, making them ideal for agricultural irrigation purposes.
