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 the telecommunications industry?: Yes, plastic tubes are suitable for use in the telecommunications industry. They are lightweight, flexible, and can easily be installed in various settings. Plastic tubes are also resistant to corrosion and offer protection to the cables and wires used in telecommunications systems.

Q: The plastic tubing split for the dispenser. When the water switch is pressed, water goes pretty much everywhere but the glass. The split is in the arch and there doesn't seem to be any slack in the tubing in the door.

One engineer pronounced 'look, woman, you have have been given to recollect that this is not pronounced as an American refrigerator-freezer for not some thing, and you already understand how plenty ice they eat, quite indoors the warmer states? so so which you may extract various bowls of ice from it on a daily basis no count huge form in case you recommend to stick to them or not.' For a on the comparable time as that worked, yet i could desire to admit that sitting someplace on the record of 'subject concerns to get around to doing' is fixing the ruddy ice-dispenser, through certainty it has actual seized up and that i won't be in a position to be waiting to undergo the belief-bearing directly to the disruption of having it fixed yet. i don't comprehend no count huge form if this is your undertaking, yet i presumed i could proportion it.

Q: i bought 6 goldfish and there in a plastic tankbut theres no air tube yet i have a bigger tank that i need 2 set up but do my fish have enough air cuz there like coming to the surface like there trying to get air: Is it available which you will head the sparkling out from the 5 gallon tank to the ten gallon tank? if so, you will now no longer could complication approximately cycling via employing certainty just about all the bacteria colony is cutting-edge on the sparkling out media so which you would be shifting the colony with the fish. If now no longer, are you waiting to place a great number of the media from the properly-time-honored sparkling out into the present one. which could help speed the cycle. As for shifting them, to cut back the stress, i might make the circulate an afternoon after a undemanding water replace. That way the water maintains to be sparkling. circulate the water from the triumphing tank without delay into the present tank and located the fish in it. this would not help with the cycling as there is not any clever bacteria cutting-edge indoors the water even in spite of the shown fact that it rather keeps them indoors the water they're familiar with so which you will now no longer could bypass contained in process the acclimation ability of putting them in a bag and floating them. Then slowly upload extra water back in to end filling the present tank. basically ensure you make the main of dechlorinator and that the temperature and pH of the sparkling water is related to the comparable via employing certainty the water they're in. Temperature swings are no longer fairly a lot as undesirable as pH swings. given which you will probable be staring at inclusive of roughly 5 gallons, i might say upload some gallon each 15 to 20 minutes till complete. If the pH and temp are the comparable, then bypass forward and fill it up. Goldfish are very hardy so that they might desire to do intense-high quality. One very final element, as without delay as you're complete, turn the lights furniture furniture off for a number of hours so that they might recover from the stress. they are going to manage it extra suitable without the lights furniture furniture.

Q: Can the tap water plastic pipe connect with the old water pipe?: SureYou can buy one with a convertible head.NamelyOne end is PPR or PVC and the other end is stainless steel.You go to the hardware store and ask the boss. Say to water transfer head (specific size look at do). Say "PPR" or "PVC" to your boss. The other end is made of stainless steelBut you have to make sure. Stainless steel part.
