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 use in food and beverage industries?: Yes, plastic tubes are suitable for use in food and beverage industries. They are often made from food-grade materials that meet stringent safety and hygiene standards. Plastic tubes offer various advantages such as being lightweight, easy to clean, and resistant to corrosion. They are commonly used for packaging, transporting, and dispensing food and beverage products efficiently and safely.

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: My two young female gerbils are chewing on the CritterTrail plastic tubes I have connected to the cages. They have tons of chew toys, food, and space. I've placed two toilet paper holders in their large nest area. It's helped a little, but they still chew on the plastic tubes. Which is VERY noisy, and I don't think chewing on plastic is good for them compared to natural wood.: No matter what you do, I'm afraid they're not going to quit chewing until they're bored with it. I went through the same deal. What I suggest is take them out and place them in a pin of sorts and place different objects (that you don't mind being chewed on) in the pin with them. Try to get them to find something they like more than that. If not then hell, you tried. It won't hurt them eating the plastic dear so don't worry about that. They don't always eat natural wood anyway they prefer, well, whatever they can get their paws on :) Good day and good luck

Q: he dips one end at the gasoline at the tank, why does the tecnique work: because the suction of dipping the hose in the tank makes a vacuum that pulls the gas out of your tank.

Q: How can I clean my hookah pipe? I have a clear plastic medical tubing as the pipe (quick fix buy works great lol) and I can easily take it apart to clean BUT it's got tar stains inside the tube now, and I can't get the tar stains out of the plastic tube, I've tried bleach and some mild abrassive cleaners, even soap. Any tips?: Use isopropyl alcohol (rubbing alcohol).

Q: At night my hamster wakes up and plays and stuff, well he has these plastic tubes that he can climb up to get to different areas of his cage, he likes to chew on them. My only problem is that it is REALLY loud and I hate the scraping sound it makes. I don't want to take out the tubes because then he would have nothing to play in. And I don't have the money to get him a new cage/glass aquarium and I really would like him to stay with the cage he has now, it's an all plastic cage except the metal bars to keep him in,lol, the brand is Super Pet Critter Trail if you want to loo it up to see what I'm talking about. Me and my mom have tried rubbing lemon juice on it but he liked the taste -.- please help?: Plain wood chew toys would give him something to play with (don't get coloured ones as the dye might not be safe). The chewing should be less noisy, but he might still prefer to chew the plastic (make sure he doesn't swallow any as this could give him an intestinal blockage).The alternative is simply to move him in to another room at night; that is safe and solves the problem.

Q: How does using a plastic tube instead of a rubber tube affect the rate at which water flows through it?: You may look up the manning's number for the effect of using different materials.

Q: How are plastic tubes filled with adhesives or sealants?: Plastic tubes are typically filled with adhesives or sealants through a process called tube filling. This involves using specialized equipment that dispenses the adhesive or sealant into the tube, while ensuring proper measurement and uniformity. The tube is filled by either manual or automated processes, where the adhesive or sealant is carefully transferred into the tube's opening using a nozzle or syringe. Once filled, the tube is sealed to prevent any leakage or drying out of the adhesive or sealant.

Q: I own a 1995 Toyota Celica. A plastic tube next to the aluminum tube eventually rubbed a hole. Can this aluminum tube be repaired, or do I have to replace the entire thing?: doubt you can patch it, if it's high pressure it's not worth it in the long run. Days are really hot and cars build a lot of pressure in the lines. Best bet, get it replaced with one that comes from a wrecked car, it's the cheapest way to go. Never buy the part from a dealer.

Q: How are plastic tubes labeled for identification?: Plastic tubes are commonly labeled for identification using various methods such as adhesive labels, heat-shrink sleeves, laser engraving, or direct printing on the surface of the tube.
