It is made by a process called polymerization, this is where they take lots of monomers (in this case ethene) and combine them together using an addition reaction. This is only possible in monomer where there is a double bond as to add them the double bond has to break for there to be enough room on the carbon for the new monomer. This process is done millions of times and is finally makes polythene which is used to make bin liners and poly bags.
This is the proses:
Crude Oil -> Crude Oil Vapour --> Diesel Oil --> Ethene --> Polythene
What else can I help you with?
Why are plastic bags made from non deagradeable polyethlene?
plastic bags are made from non deagradeable polyethlene because its a flexible strong material and is not deagradeable
What is the abbrevaiation of high density polyethlene?
HDPE
What is HDE pipe?
high density polyethlene pipe
What has the author R D Wiles written?
R. D. Wiles has written: 'The thermal and thermo-oxidative degradation of polyethlene terephthalate'
Is PVC and polyethylene the same thing?
They are similar but different. PVC is stronger & more rigid than polyethlene and is used for wastelines & polyethylene is used for water lines.
What type of plastic are a dustpan and brush made out of?
A dustpan and brush are typically made out of polypropylene or high-density polyethylene, which are durable and lightweight plastics commonly used for household products. These plastics are chosen for their strength, flexibility, and ability to withstand frequent use and exposure to cleaning agents.
How many meters in one kilogram polyethylene roll?
It is not possible to tell the number of meters in one kilogram polyethlene roll. This is because, meter measures length while kilogram measures weight.
What types of fittings can you use on yellow polyethlene natural gas pipelines?
Pretty much any fitting that will fit. Narural gas is naurally leak averae and wont leaak out of fittings, only pipes with holes.
What is polyethylene glue?
Polyethylene glue is an 'urban myth'. Modern polyethlene materials are purposely so chemical resistant that no glue has yet been made that will bond them ! Polyethylene pipes are bonded by 'hot air' welding, not by any glues. They can be held together by contact adhesives, but the joint is very weak and will not hold even 30psi of water or air pressure.
What are the three layers of aluminum foil?
Pure aluminium foil (not mylar), has three layers, a protective oxide coating on each face of the foil, and pure metal inbetween. Mylar is a metallised plastic, one variety has a polyethlene terephthalate film coated on both sides with a thin layer of aluminium. From a microscopic view the aluminium layer has a protective layer of oxide.
What type of polymer is used in the windshield of airplanes?
The airplane is encountering quite a force when flying. Polymer is used because it is extremely strong. It will try to "absorb" an impact rather than just break into little pieces. A windshield/window of an airplane is designed to withstand the actual impact of even largish birds. At some time they did indeed test windshields/windows for planes with something commonly known as a Chicken Gun. In the early days there was a person who smashed one windscreen after another and he could not understand why because they should withstand it. After a while somebody asked him if he had defrosted the chicken first. Ooops. The windscreens on airplanes are not tough enough to withstand frozen solid birds.
How are cermaics made and how are they made?
