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:Connecting icemaker valve to 1/4" tubing?
I never did like plastic, try copper tubing.
Q:What is the white plastic water pipe material commonly used in engineering?
The radial ribbed tube is adopted in the production of special tooling and molding process of UPVC plastic pipe, which is characterized by reduced wall thickness, but also improve the ability of pipe under external pressure load, the outer wall of the tube with radial stiffeners, improve the ring stiffness of the pipe. Under the same external load, the pipe material can save about 30% of the material compared with the ordinary UPVC tube, and the pipe diameter can be processed to DN500mm.
Q:Is there a safe & secure way to add plastic bubble tubes to a wire hampster cage?
yes use zip ties, they come in all colors and are very strong and nontoxic
Q:Are buried plastic pipes covered with sand?
Only when the plastic pipes are laid at the bottom of the stone trench, will the 100mm soil or sand be placed on the top and bottom of the plastic pipes.
Q:A plastic tube allows a flow of 13.3 cm3/s of water through it. How long will it take to fill a 220 cm3 bottle?
220/13.3=16.5
Q:Is the water pipe made of stainless steel or plastic pipe?
Natural purified water, which is transported through plastic pipes for a long time, can cause serious damage to water quality and greatly reduce people's health index. The stainless steel pipe is not easy to rust, can guarantee water quality and health.
Q:Attempting to change the spark plugs in '00 Jeep Grand Cherokee. How do I get the plastic tubes off the plugs?
kind of turn them as you pull no them,they will let go ,but they can be really stubborn to get off,especially if they haven't ever been changed before,don't pull on the wire part its self,it will pull the wire out of the holder and tear the end off of it,keep twisting it and it will eventually get loose,good luck on it.
Q:Where can I buy golf club protector tubes in Toronto?
Do yourself a favour don't buy them,they are a pain in the neck.
Q:fish tank pump tube problems?
using standard size plastic tubing like other air pumps on the market (about 5-6mm in diameter)
Q:How do you sand the inside of a tube?
take a wood dowel make a cut in one end for a flap of sand paper to fit in, attach loose end to a drill , turn it on run plastic tubes back and forth on sand flap [make a sanding rod]
