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:
Yes, plastic tubes can be used for bottling beverages.
Q:just needed to know before i ran into a potential disaster! lol -any tidbits of advise would be gladly accepted =)gt;
Hi, without any details it's difficult speculate but if you have never done anything like this before successfully or the tanks contain living creatures I would say forget it-the potential for disaster is VERY great! As a caveat have a look at the link below for what is possible with a great deal of money, time engineering know-how.
Q:
Yes, plastic tubes can be resistant to bacterial growth. Many plastic materials used in the production of tubes have antimicrobial properties or can be treated with antimicrobial coatings to inhibit bacterial growth. Additionally, plastic tubes are often designed to be non-porous and have smooth surfaces, making it harder for bacteria to adhere and multiply. However, it is important to note that the resistance to bacterial growth may vary depending on the specific type of plastic used and the conditions in which the tubes are used and stored.
Q:Is it OK to drink water with plastic pipes at high temperature?
If the plastic pipe is non edible standard, then there must be a problem, plastic meets high temperature will be deformed, and release harmful substances, long-term drink so, will certainly affect health
Q:
Yes, plastic tubes are lightweight.
Q:
Yes, plastic tubes are suitable for packaging small components or parts. They provide protection, are lightweight, and can be easily customized to fit different shapes and sizes. Additionally, plastic tubes can be sealed securely to prevent damage or loss during transportation.
Q:
Yes, plastic tubes can be used for storing food ingredients. They are commonly used for storing dry ingredients such as spices, herbs, and powders. However, it is important to ensure that the plastic tubes are food-grade and have proper sealing to maintain the freshness and quality of the ingredients.
Q:
Yes, plastic tubes are generally resistant to both abrasion and scratching. They are designed to withstand rough handling, repeated use, and exposure to various environmental conditions without losing their integrity or being easily damaged.
Q:
Plastic tubes and polyvinyl chloride (PVC) tubes are essentially the same thing. PVC is a type of plastic that is commonly used to manufacture tubes due to its durability and resistance to chemicals and weathering. Therefore, there is no significant difference between plastic tubes and PVC tubes in terms of durability.
Q:I am saving state quarters for my daughter. I have noticed that some of the quarters are getting a bronze look to them. I don't know if it is the entire roll or simply the ones on the end. I have placed the coins in the squared plastic tubes and then in old army ammo boxes. I desire her being able to take them out in 20 to 30 years in brilliant uncirculated condition. What is the best way to store them?
Hello, many things can change the colour of coins. Most of the metals that coins are made of are affected by compounds in the air and anything they are near such as sulfur and nitrates. Most often its just the end coins in the roll that are most affected. An ammo tin is definitely not the place to keep them. Best place would be in your tubes as mentioned, as long as you got them at a coin store and they are chemically inert. Then placed in an air tight Tupperware container with a bunch of those silica packs that you get in electronics boxes, shoes ect. Make sure to change them every few years to prevent any moisture from building up.
