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 storing chemicals?: Yes, plastic tubes can be used for storing chemicals. However, it is important to consider the compatibility of the specific chemical with the material of the tube to ensure safe storage and avoid any chemical reactions or degradation.

Q: it has one hose connected to one end and two hoses on the other end. think it might have something to do with heater core or something.: the single end is attached to the lower radiator hose the double end one hose goes to the lower part of the intake and the other goes to the heater core this is just a transfer tube across the front of the vehicle

Q: I was wonder If Plastic Pluming Tubes Yes WITH end caps would work for pontoons if you know tell me Thx -Zac: Yes okorder hope this helps

Q: the tube is running from the cold water tap of the laundry sink. there is always a trickle of water. the tube appears to have been placed in the cement floor at the time of construction. i can think of nothing it feeds. would like to get rid of it but want to know why its there first.: could be a trap primer. If you have a floor drain in the basement floor, this line trickles water into the trap under it so it wont dry out, keeping the sewer gasses in check. If no floor drain then I dont know either!

Q: Can plastic tubes be used for cable protection?: Yes, plastic tubes can be used for cable protection. They provide a protective covering for cables, helping to prevent damage from external factors such as moisture, dust, and physical stress. Plastic tubes are commonly used in various industries and applications to ensure the longevity and reliability of cables.

Q: What is the maximum pressure plastic tubes can handle?: The maximum pressure that plastic tubes can handle depends on the specific type of plastic and its thickness. It is important to consult the manufacturer's specifications or testing data for the specific plastic tube being used to determine its maximum pressure rating.

Q: Can plastic tubes be used for ventilation systems?: Yes, plastic tubes can be used for ventilation systems. They are commonly used in residential and commercial buildings as flexible air ducts due to their durability, lightweight nature, and ease of installation. Plastic tubes offer good airflow and insulation properties, making them suitable for various ventilation applications.

Q: It is for a plastic tube that goes from the engine of my motorized paraglider to the inlet of my new gas tank. The plastic is a little too tight and I can't warm it up with a flame because of gasoline that may still be in the engine.: Then try going the other direction and freezing the smaller tube. That may make it shrink enough to fit.

Q: What is the maximum diameter-to-length ratio for plastic tubes?: The maximum diameter-to-length ratio for plastic tubes can vary depending on the specific type of plastic and the intended application. However, in general, the maximum diameter-to-length ratio for plastic tubes typically ranges from 1:10 to 1:20.
