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 am doing a project and i have a plastic tube that need to go in circles so i need to straighten it. Any Ideas? I need this fast please. :): get a differeant tube

Q:plz answer this question its for school: If your a witch does it imply your going to hell? No. Hell does no longer exist, so no person can cross to it. If no longer then what do you name a well witch? The equal factor you name a foul witch or any type of witch in-among. A witch. Is there a distinctive title? Witchcraft is a device that any one can use, a witch is anybody who makes use of that device. IT can be utilized for lots of matters, the significance you location on it's arbitrary and subjective... damage or aid... Good or dangerous aren't absolutes... they depend on judgement, opinion and revel in. If your a witch does it have an impact on your loved ones spirtually, bodily, emotionally, and mentally? That relies on your loved ones and relies on the witch. It could be a very confident factor if the witch protects and aids his/her loved ones with witchcraft. -Scarlet

Q:I need to clean my gravel and have read a bunch of reveiws on the gravel cleaning syphons and I don't want to waste my money on a cleaner that doesnt work. I might not be using the correct term for the product, it is one of those tubes that you shake to create a syphon. Thanks for all your help: The easiest way is to suck on the end of the tube to draw up water and kink the tube or use your finger to cover the end .to keep the water near to the end. Then lower the end to the container and let off your finger. The weight of water in the tube and gravity will do the rest. As long as you have the end of the tube above the level of water in the tank while you are drawing water into the tube, you will NOT get a mouthful as you can see to stop just before the water gets to the end. I am sure you are smart enough to stop before you get a mouthful of water. As long as the end is above the level in the tank the siphon will NOT start and you will have to apply suction to hold the water in the tube until you kink it or use your finger to seal the end. The only way to get a mouthful is if your mouth is lower then the level in the tank so the siphon starts once the water crosses the threshold, Be careful not to suck up the fish...

Q:Is plastic pipe polythene good or polypropylene?: According to the application to decide if it is drinking water pipes, rainwater pipes, gas pipes, industrial anti-corrosion pipeline, pipe polyethylene material; in case of chemical sewage, sea water, oil and irrigation pipe, pipe for indoor heating system for concrete floor heating pipe, pipe selection of polypropylene.

Q:UPVC what material is the pipe and the HDPE plastic pipe?: UPVC is modified polyvinyl chloride. The tubing is brittle, flexible, and has a weak connection. HDPE is high-density polyethylene, flexible tubing, -60 degrees - 40 degrees can be safely construction. The use of hot melt and electrofusion connection method is very strong, generally used for drinking water supply pipe, gas pipe, coal pipe, etc..

Q:Can plastic tubes be used for playground equipment?: Yes, plastic tubes can be used for playground equipment. They are lightweight, durable, and can be easily molded into various shapes and sizes, making them suitable for creating slides, tunnels, climbing structures, and other components of playground equipment. Additionally, plastic tubes are often weather-resistant and require minimal maintenance, making them a popular choice for playgrounds.

Q:What kinds of plastic pipes are available? Which ones are free to deform and turn?! At the same time can bear the pressure of tap water!: According to various plastic molding methods, can be divided into film pressure, lamination, injection, extrusion, blow molding, casting plastics and reaction injection plastics and other types.

Q:Can plastic tubes be used for greenhouse installations?: Yes, plastic tubes can be used for greenhouse installations. Plastic tubes are often used to create a framework for greenhouse structures due to their durability, flexibility, and cost-effectiveness. They provide a lightweight and easily customizable option for constructing greenhouse frames, allowing for efficient installation and maintenance. Additionally, plastic tubes can be easily shaped and connected to form various greenhouse designs, making them a popular choice for greenhouse installations.

Q:Can plastic tubes be used in high-pressure applications?: Yes, plastic tubes can be used in high-pressure applications, but it depends on the specific type of plastic used and the pressure level required. Certain types of plastic, such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), and polypropylene (PP), have good resistance to pressure and can withstand high-pressure environments. However, it is important to consider factors like temperature, chemical compatibility, and the specific requirements of the application when selecting plastic tubes for high-pressure use.

Q:Do plastic tubes have any limitations in terms of temperature resistance?: Yes, plastic tubes have limitations in terms of temperature resistance. Different types of plastics have different temperature thresholds beyond which they may deform, melt, or become brittle. It is crucial to choose the appropriate plastic material for specific temperature ranges to ensure optimal performance and durability.
