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:instead of using ridgid conduit can polytubing or irrigation vinil pipe be used as an option or cable can just run bare on concret on a house been build up of concret wall in and out ?: You should use sched 40 pvc conduit. It does not have to be buried very deep inside of a buliding, but I would suggest scatching it down a few inches below the concrete pour just in case you ever have sawcut the floor. DO NOT USE IRRIGATION PIPE. Never use 1/2 conduit underground. Use 3/4 or larger.

Q:Can PVC pipes be used with drinking water?: At present, the domestic PVC processing is good and bad, there may be lead salt as a stabilizer for the water supply pipe.It is safe to use PVC water pipes that are not guaranteed by lead salts as stabilizers. Its physical and chemical properties still have advantages in plastic pipes.

Q:Are plastic tubes suitable for storing chemicals?: Plastic tubes can be suitable for storing certain chemicals, but it depends on the type of chemical being stored. Some chemicals may react with certain types of plastic, leading to degradation or leakage. It is important to consider the compatibility of the chemical with the specific type of plastic used in the tube. In general, it is recommended to use glass or specialized chemical-resistant plastics for storing hazardous or corrosive chemicals.

Q:I need some plastic tubes to put bath salts in. Does anyone know where I can find them. I need these by Saturday.: You can most generally find them in your nearest craft store . If not maybe try asking your female friend's and relatives if you may have there empty shampoo and conditoner , and handcream bottle's .

Q:How are plastic tubes stored to maintain their shape?: Plastic tubes are typically stored in a way that ensures they maintain their shape. This can be achieved by storing them in a vertical position, preferably in racks or holders, to prevent bending or warping. Additionally, storing them in a cool and dry environment helps to prevent any potential deformation caused by heat or moisture.

Q:Can plastic tubes be used for insulation in construction?: Yes, plastic tubes can be used for insulation in construction. Plastic tubes, particularly those made from materials like polyethylene or PVC, are commonly used as insulation for pipes, electrical wires, and HVAC systems in construction projects. These tubes have good insulating properties, are lightweight, and are resistant to moisture, making them an ideal choice for insulating various components in buildings.

Q:I have a 1 year old Robo hamster named Jewel. She has PLENTY of food (slightly chubby lol) and things to chew on..yet she is chewing on the plastic hamster tubes? She lives in a 10 gallon tank and has a silent spinner and toys (and a hut) 1.can she chew THROUGH the tube and escape? 2.can this hurt her health?: 1) No, the tube would be pretty hard to get through for its rounded shape. 2) Only if she swallows the plastic, which is highly unlikely, as I said before, it would be unlikely for her to physically chew through the tube. Check on her occasionally, and make sure to get her used to chew toys, I have cardboard tubes (from Pets at home) for both my Guinea Pigs and Hamster ^^

Q:Are plastic tubes suitable for use in the oil and gas industry?: Yes, plastic tubes are suitable for use in the oil and gas industry. They offer numerous advantages such as resistance to corrosion, chemicals, and high pressure. Plastic tubes are lightweight, durable, and easy to install, reducing both costs and maintenance requirements. Additionally, they allow for better flow rates and are compatible with various fluids and gases used in the industry.

Q:Where can i buy flexible plastic tubing od 2mm?: A place that has aquarium supplies

Q:I don't mind cutting the wire but I want to make sure hampster won't get hurt the bubble tube can't be pushed off by her.: You can fold the wire back so that there are no sharp edges when you cut. You can certainly use zip ties, just check them to make sure your hamster doesnt chew them off. Be creative. Modified cages are fun to make!
