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 are the different types of plastic tubes available?: There are several different types of plastic tubes available, including PVC (polyvinyl chloride) tubes, PE (polyethylene) tubes, PP (polypropylene) tubes, and PTFE (polytetrafluoroethylene) tubes. Each type has its own unique properties and is suitable for specific applications.

Q: How do you clean clogged plastic tubes?: To clean clogged plastic tubes, you can try a few methods. First, try using a plunger to create pressure and dislodge the clog. If that doesn't work, you can use a mixture of hot water and dish soap to break down any grease or grime causing the clog. Alternatively, you can try using a pipe snake or a wire hanger bent into a hook shape to physically remove the blockage.

Q: Can plastic tubes be used for storing small parts or components?: Yes, plastic tubes can be used for storing small parts or components. They provide a convenient and organized way to store and transport small items, keeping them safe and easily accessible.

Q: Why fire water pipes do not use PVC plastic pipes?: Because of the lower level of safety guarantee, the water for domestic use can be maintained without water at any time. Therefore, fire pipe network requires steel pipe instead of PVC pipe.

Q: Can plastic tubes be connected or joined together?: Yes, plastic tubes can be connected or joined together using various methods such as adhesive bonding, welding, or using connectors like fittings or couplings.

Q: I have a question. I have a air pump and some of the plastic tubing in my aquarium right not. Well, the plastic tubing has hardened and just will not stay in place. So I am thinking of going and purchasing some of the silicon airline tubing. I have a treasure chest and a sunken ship in the aquarium, but they do not have the hookup (airstone). So, I just put the tubes let the air come out of the end. Do I have to have an airstone? I haven't up until now and the bubbles are big. What do I need to purchase when I go to the pet store? Thanks!: Hi! I am in the process of doing the same thing! The first thing you need to figure out is the actual size of your fish tank because that is going to determine the size of the filter and heater that you need, not to mention, how many fish you can put in your tank. The rule of thumb is one inch of fish per gallon of water for most freshwater tropical fish. It is different for goldfish and african cichlids though. Here is the list of things I would get: BASICS: heater, power filter, water conditioner, thermometer, fish net, tropical fish flake THEN: gravel, plants, tank background, decorations, lighted hood(flourescent is best), beneficial bacteria, a gravel siphon for cleaning, get a self starting one, it's worth the extra few dollars, bucket strictly for water changes. Take a tap water sample to the fish store with you so you know what pH you are dealing with. Angelfish like a slightly acidic pH between 6.5 and 6.8. They can be acclimated to other levels though. Take the time to do some research on the nitrogen cycle and acclimating your fish. It can save the life of your fish. Angelfish are great fish with alot of personality. I hope you enjoy yours!

Q: Can plastic tubes be used for storing powders or granules?: Yes, plastic tubes can be used for storing powders or granules. They are commonly used in various industries such as pharmaceutical, food, and chemical, as they provide a convenient and hygienic storage solution. Plastic tubes offer good barrier properties, protecting the contents from moisture and external contaminants. Additionally, they are lightweight, easy to handle, and can be sealed tightly to ensure the integrity of the stored powders or granules.

Q: What is the maximum pressure that plastic tubes can handle?: The maximum pressure that plastic tubes can handle varies depending on the type of plastic and the specific application. However, plastic tubes can typically withstand pressures ranging from a few hundred to several thousand pounds per square inch (psi). It is important to consult the manufacturer or specific product guidelines for accurate pressure ratings.

Q: I am going to have breast lift surgery and I reaaaallllly don't want to have the drainage tubes if not necessary of course.I've seen someone women that have them and some don't.Is there any way to prevent it?: if you get breast implants or aesthetic surgery of any kind on the breast and anytime later in life you get breast cancer (1 in 9 chance) health insurance wont cover it. it costs more than 100,000 to treat breast cancer typically

Q: What are the raw materials for plastic pipes?: Plastic pipe raw material is plastic particles, according to the pipeline production processing performance requirements, with the different requirements of finished products, there are different manufacturers grades, grades and performance differences.
