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 suitable for wastewater management?: Yes, plastic tubes are suitable for wastewater management. They are commonly used in various applications such as sewer lines, drainage systems, and underground water management. Plastic tubes offer benefits like durability, corrosion resistance, and ease of installation, making them a reliable and cost-effective option for managing wastewater.

Q: i have a plastic tube that i want as a handrail how do i do it, cos tube is 1 inch wide: There okorder /

Q: What are the high temperature resistant plastic pipes?: Since the outer surface is a thermoplastic material, the radiation temperature outside the tube shall not be higher than 280 DEG C when necessary. A sleeve without thread shall be added to the surface for use

Q: What is the name of the clear plastic tube like thing you can fill with water, and then squeeze gently to let a stream of water clean out the area where a tooth was recently removed?: You can use either of the following : 1. A syringe. Usually the dentists give you a syringe without a needle. The one that is commonly given out is the monoject syringe that has the tip built into it with a slight curve. That means it is a one piece plastic syringe with the dispensing tip and a plunger. 2. You can also use a WaterPik or Water Jet Hope this helped :)

Q: Will the results be any different? If so, why?: Absolutely they'll be different. The normal plastic bad is not permeable to much of anything. I'm not sure of your experiment, but if you are using starch and Iodine, with dialysis tubing, the iodine can pass in and out, but starch cannot because the pores in the dialysis tubing are too small. With a platic bag, there are no pores, per se, and so neither the iodine nor the starch can move in and/or out.

Q: Plastic pipes have steam, how to handle dry?: We like PC plastic pipe is the use of air blowing dust, water vapor will suggest that you try the effect

Q: how do you get 2 pieces of plastic tube unstuck?: Try this, make one end cold and the other end hot. The cold pipe will contract and the warm pipe will expand, making it easier to separate.

Q: I would like to give all the girls in my daughter's dance company single stemmed roses after they compete in an upcoming dance competition. I tried last year just keeping the flowers in the car in water but that didn't work very well. Plus it was a hassle getting them from the car since I had my daughter's costumes, make up, etc and other props. I would like to this year use those individual water tubes that usually come on single stemmed flowers but I'm not finding them. I am buying for about 30 girls so I need to keep this as affordable as possible. Any ideas on how to create a homemade version or buy them for cheap? I will call a florist but I'm anticipating them not selling to me because they would want me to buy the roses from them (I am just buying about 2 1/2 dozen and doing it myself.Thanks so much!: You might try using plastic tubing and plugging the ends. Glass tubing is another way to go, more durable but also more expensive more work. Glass tubing can be cut to length then closed off on one end by heating in a flame until it pulls together. Large drinking straws could work as well, you could seal the bottoms with an iron by placing the straw between aluminum foil sheets.

Q: What is a paintball power tube used for?Im looking into an tippmann A5 power tube Delrin Front Bolt. Whats the difference and benefits.Thanks: The power tube is the part that holds the valve in the marker and helps direct air flow. Getting a new power tube will do NOTHING to performance. It has no performance valve what so ever. The front bolt is the part that helps push the ball out or the chamber. And getting a new one will help very very lil. So lil that it doesn't really matter. THis is because the stock front bolt on the tippmann markers is made so well that changing it doesn't make it any better because they will perform just about the same. Replacing the stock power tube to a full aluminum power tube is a good idea because after a while the stock plastic power tube does tend to break and when that happens it will cause air or co2 to leak. The aluminum one wont do that and lasts a lot longer.
