What is the weight of polyethylene?
What is the weight of polyethylene?
The molecular weight of polyethylene can vary from 30,000–6,000,000 g/mol, density can range from 0.91–0.98 g/cc, and crystallinity can span 30–90%. The melting temperature is typically in the range of 120–147°C and the glass transition temperature is on the order of −80°C.
What is the formula of polyethylene?
(C₂H₄)ₙ
Polyethylene/Formula
How do you find the molecular weight of polyethylene?
Calculate the molecular weight of the monomer unit by multiplying the atomic mass of each element by the number of atoms in the monomer of each, then add the products. For tetrafluoroethylene, the molecular weight of the monomer unit is 12 x 2 + 19 x 4 = 100.
What is the molecular weight of polypropylene?

What is an example of polyethylene?
Bubble wrap used for packing fragile dishes is an example of polythene. Polythene is a light type of plastic used for insulating and packaging. An example of polythene is what something would be wrapped in for safety during shipping.
What can dissolve polyethylene?
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. Polyethylene absorbs almost no water.
Where is polyethylene found?
It is found in countless everyday items, and it also is one hundred percent recyclable. Polyethylene is valued for its strength and lightness, and it is used in plastics bags, bottles, caps, lids, pipes, containers, and more.
How can you tell the difference between polypropylene and polyethylene?
Difference Between Polyethylene and Polypropylene
- Polyethylene is formed through the polymerization of ethylene monomer units.
- Polypropylene is formed through the polymerization of propylene monomer units.
- Polyethylene is less rigid and more flexible.
- Polypropylene is quite rigid.
- Polyethylene is a translucent material.
What is polyethylene used for?
Polyethylene is crystalline, translucent, and thermoplastic—i.e., it softens when heated. It is used for coatings, packaging, molded parts, and the manufacture of bottles and containers.
How much does a cubic foot of polyethylene weigh?
In Imperial or US customary measurement system, the density is equal to 59.93 pound per cubic foot [lb/ft³], or 0.555 ounce per cubic inch [oz/inch³]. Also known as: HDPE. Molecular formula: (C 2 H 4)n Elements: Carbon (C), Hydrogen (H)
What is the chemical formula for polyethylene ( PE )?
Polyethylene (PE) is an organic polymer made by the polymerization of monomer subunits. The chemical formula of polyethylene is (C2H4)n. Polyethylene is a combination of similar polymers of ethylene with different values of n. A typical polyethylene molecule can contain more than 500 ethylene subunits.
What’s the molecular weight of a linear polyethylene?
Ultrahigh-molecular-weight polyethylene Linear polyethylene can be produced in ultrahigh-molecular-weight versions, with molecular weights of 3,000,000 to 6,000,000 atomic units, as opposed to 500,000 atomic units for HDPE.
What is the formula for a polyethylene thermoplastic?
The general formula of polyethylene can be written as (C 2 H 4) n. Most types of polyethylene are thermoplastic (they can be remoulded by heating).
