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 marine industry?: Yes, plastic tubes are suitable for use in the marine industry. Plastic tubes are lightweight, durable, and resistant to corrosion, making them ideal for various applications in marine environments. They are commonly used for fluid transfer, electrical insulation, and structural supports in boats, ships, and offshore structures. Plastic tubes also have good resistance to chemicals and UV radiation, further enhancing their suitability for marine applications.

Q: water frezzes in tube fill icemaker, if I clear out it works fine a couple times and then frezzes up again.: Turn your freezer thermostat down just a little at a time until the plastic line stops freezing

Q: How long do plastic tubes typically last?: The lifespan of plastic tubes typically depends on various factors such as the quality of the material, the conditions they are exposed to, and how they are used. However, on average, plastic tubes can last anywhere from a few years to several decades.

Q: This tube is found when u remove the silver engine cover.I need to buy this tube cos its broken. It looks like an exhaust oil channel (not sure). it was noted to be broken/cot during a recent service and I was told only citroen dealers can have it in stock.Car runs fine but I occasionally smell oil while driving.: It sounds like some kind of breather pipe to me, probably the best thing to do is to roll into your local Citroen dealer and ask someone in parts to look at it and they should be able to get you one then.

Q: Is it OK to drink water with plastic pipes at high temperature?: From the point of view of hygiene, as long as the plastic tube is clean, there is no problem. But from a safe point of view. If the plastic pipe is a straw used for common drink, it belongs to normal temperature and is safe.

Q: Can plastic tubes be used for medical applications?: Yes, plastic tubes can be used for medical applications.

Q: How to calculate joint parts for hot melt connection of water supply plastic pipe?: The hot melt connection directly connects the pipe and does not need the fittings,If flanges, flanges, or hot melt inserts or electrofusion connections are used, the fittings shall be determined according to the design drawings and field conditions.

Q: My 27 lb 4 year old dog possibly ate my Chapstick including the plastic tube. It was pretty small and he has not been acting any differently. My major concern is the plastic part. How soon would I start seeing symptoms if it was causing problems? It's been 24 hours since he ate it. Is something like that passable? Any insight would help! I say he may have eaten it only because I didn't physically see it happen. But one minute it was on the floor and then a minute later all i could find was the cap.: Yes it#x27;s possible. You should search very carefully for the container and if you still don#x27;t find it you may call your vet. If the plastic is going to hurt your dog you may have to force him to drink a little bit of hydrogen peroxide. I had to do this when my dog ate a poisonous frog. Your dog will vomit multiple times if you do this and it will be very pitiful to watch but could save his life

Q: How does groundwater flow into a well pipe? It was a small bore well, made of plastic tubing: The deep well is the filter pipe, and the deep well filter pipe is placed in the underground water layer where the water is to be taken. Some unsuitable water quality underground water layer will not place the filter pipe, so as to avoid using it.

Q: Can plastic tubes be used for water filtration?: Yes, plastic tubes can be used for water filtration. Plastic tubes can be incorporated into various filtration systems, such as reverse osmosis or activated carbon filters, to effectively remove impurities and contaminants from water. These tubes are commonly used in both commercial and residential water filtration systems due to their durability, flexibility, and ability to withstand exposure to water.
