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 roller coasters?: Yes, plastic tubes can be used for roller coasters. Plastic tubes are a popular choice for constructing roller coaster tracks due to their durability, flexibility, and cost-effectiveness. They offer a smooth and lightweight surface that allows for thrilling twists, turns, and loops. Additionally, plastic tubes can be molded into various shapes, allowing for creative and exciting roller coaster designs.

Q: Can plastic tubes be used for fuel transportation?: Yes, plastic tubes can be used for fuel transportation. Plastic tubes offer several advantages such as flexibility, durability, and resistance to corrosion, which make them suitable for transporting various types of fuel. However, it is important to ensure that the plastic material used is compatible with the specific fuel being transported and complies with safety regulations to prevent any potential risks.

Q: It comes in a plastic bag, no information is on it such as what plastic number it is. Tried google but nothing relevant is coming up.PLEASE LIST RESOURCE.Thank you.: I had a lot of trouble with my lungs for a number of years after I contracted chicken pox (went into my lungs). I ended up with quiet a bit of tubing. I had fishtanks, and that tubing is perfect for conecting different air hoses in fishtanks. Same stuff you purchase at the pets stores, and pay quiet a bit for. If you don't have fishtanks yourself, you can offer it to someone who does. It can be re-used on fish tanks quiet safely for the fish. You can offer it for free on Craigslist or Freecycle to someone with fishtanks, if you don't know someone personally. ~Garnet Permaculture homesteading/farming over 20 years

Q: How can I make a frosting tube?You know, the stuff you put frosting in squeeze it out?I want it to come out thin kind of so I can write Welcome homeCan't you like put it in a regular plastic baggy?But how do I make a nozel for it to come out of?...I need one within the next half hour. I Cannot go to the store fir anything..HELP: They are both right! I just suggest you use a freezer bag, they are sturdier. I've used regular bags before only to have the seams pop half way through. Good luck!

Q: What is the connection between the wires of the PVC?: PVC wire tube (Amazon plastic) by type, light, medium and heavy specifications, mainly 16.20.25.32.40.50.PVC wire tube is good or bad, mainly look at features:1., insulation performance is good: PVC electrician bushing insulation good, high resistance to current breakdown voltage, can withstand 25 thousand volts voltage without breakdown, so PVC electrical bushings no live danger.2., strong impact resistance: PVC electrical bushings can withstand the pressure, can be concealed in the concrete, not afraid of compression, impact damage.3., fire resistance performance is good: PVC electrician bushing oxygen index is high, with flammability, leave the flame instantly extinguished.4. moisture-proof, acid and alkali: PVC electric sleeve moisture-proof, not like metal casing corrosion, and acid, alkali, oil resistance.5. insect proof mouse: PVC electric bushing will not send out the smell of insect mouse, and can avoid the bite and bite of insect mice.6. easy to bend: just insert a spring in the pipe, without heating, gently bend with the hand.7., connection way: use adhesive, direct pipe and various parts connection, can complete all kinds of wiring requirements.

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: filling a grocery cart is not an option.: Buy some boxes of jello, a large bowl, a large meat fork and some live goldfish.

Q: when u have laproscopic surgery do they stick a tube down your throat. if so what does it help do.?: Laparoscopic surgery, also called minimally invasive surgery (MIS), bandaid surgery, keyhole surgery, or pinhole surgery is a modern surgical technique in which operations in the abdomen are performed through small incisions (usually 0.5-1.5cm) as compared to larger incisions needed in traditional surgical procedures. .Laparoscopic surgery also referred to as minimally invasive surgery describes the performance of surgical procedures with the assistance of a video camera and several thin instruments. During the surgical procedure, small incisions of up to half an inch are made and plastic tubes called ports are placed through these incisions. The camera and the instruments are then introduced through the ports which allow access to the inside of the patient. The camera transmits an image of the organs inside the abdomen onto a television monitor. The surgeon is not able to see directly into the patient without the traditional large incision. The video camera becomes a surgeon’s eyes in laparoscopy surgery, since the surgeon uses the image from the video camera positioned inside the patient’s body to perform the procedure Benefits of minimally invasive or laparoscopic procedures are less post operative discomfort since the incisions are much smaller quicker recovery times shorter hospital stays earlier return to full activities much smaller scars there may be less internal scarring when the procedures are performed in a minimally invasive fashion compared to standard open surgery. The ET (endotracheal tube) is usually inserted thru your throat into the trachea.which can be hooked up to a ventilator for respirations during surgery.

Q: Are plastic tubes safe for use with drinking water?: Yes, plastic tubes are generally safe for use with drinking water. However, it is important to ensure that the plastic used is approved for food contact and meets the necessary safety standards. Regular inspection and maintenance of the tubes are also crucial to prevent any potential contamination.

Q: Are plastic tubes resistant to warping?: Yes, plastic tubes are generally resistant to warping due to their flexibility and durability. However, the extent of their resistance may vary depending on the specific type of plastic used and the conditions in which they are exposed.
