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: I have forgotten the name of the breed altough i know it starts with sy. I just want to know if they can fit in a tube cage or will they get stuck? And what is the best breed to get if you do have a tube cage?: The bigger breed of hamsters are called Syrians. You are right about them not fitting in tubes. Once syrians grow to their full size, they tend to get stuck in the tubes of commercial cages like Crittertrail etc. The best way to avoid this is to give them a non tube wire cage, glass tank or non tube plastic cage. Dwarfs can fit into tubes but again dwarfs are generally shy of climbing vertical tubes, so if you have a tall cage with long vertical tubes, your dwarfs might never use it in their lifetime. I have a cage with lots of tubes but I have placed them horizontal to the ground so that my dwarfs use the tubes.

Q: Can plastic tubes be customized with logos or labels?: Yes, plastic tubes can be customized with logos or labels.

Q: What is the average lifespan of plastic tubes?: The average lifespan of plastic tubes can vary depending on several factors such as the type of plastic used, the conditions they are exposed to, and their intended use. However, on average, plastic tubes can last anywhere from a few months to several years.

Q: The difference between metal hose and corrugated plastic pipe: The metal hose is usually made of stainless steel, or can be made of stainless steel braid. It is also made of a layer of stainless steel braid at one time. It is actually made of plastic or rubber. The main features are corrosion resistance, high temperature resistance, pressure resistance, shock absorption, and bending, easy installation.

Q: Are plastic tubes suitable for use in the chemical industry?: Plastic tubes are indeed suitable for use in the chemical industry. They offer several advantages such as resistance to corrosion, chemicals, and high temperatures. Additionally, plastic tubes are lightweight, cost-effective, and provide a smooth inner surface for efficient fluid flow. However, the specific type of plastic used should be carefully selected based on the chemical being transported and the operating conditions, to ensure compatibility and safety.

Q: Can plastic tubes be used for transporting powders?: Yes, plastic tubes can be used for transporting powders. They are commonly used in various industries such as pharmaceutical, food, and chemical industries to transport powdered substances efficiently and safely. Plastic tubes offer advantages like being lightweight, durable, and resistant to corrosion, making them suitable for transporting powders of different types and sizes.

Q: How to distinguish between hard plastic pipes and flame retardant plastic pipes?: If you can use the oxygen index method in the laboratory to distinguish, in general, the rigid plastic pipe oxygen index is lower than the flame-retardant plastic

Q: I need to buy plastic (or clear colored) plastic tubes with caps. Approximately 5 or 6 inch in length and close to 1 inch or close to it in width. Would appreciate any suggestions where I find it.: the hardware giants like Lowe's and the Ho Depot are your best bet ... go in the store and ask for plastic tubing==== HEY !! you might do better to go to a friendly pharmacy and get some clear plastic medicine bottles ... go and ASK ... and if this is

Q: i was blowing on a enclosed tube then i hear and feel a crackle between my ear and jaw and i felt like i knocked the stuffing out of my ear but i still hear perfectly normal and hear good. is something wrong and should i be concerned. my parents said it happened to them when they were little kids: Your brains exploded.

Q: inner tubes and tire. I'm looking for some advice about what to do next.: Your tire might the the culprit. Feel along the inside of the tire for abrasions or holes. Feel along the side wall of the rim. Lastly take note of where the holes are on the inner tube. You got 2 ways of doing it. pumping up the tube and putting it in a bucket and searching for bubbles, mark area with tape or with white out. You can also pump up the tube and just feel for air coming out. The first works good on tiny holes, and the second doesn't work so well with tiny holes. You could be pinching tubes as you replace them. So once you figure out how you are getting the flats fixing the cause is easier.
