Polyethylene Wax
What is polyethylene wax?
Polyethylene Wax, also known as PE Wax, is an ultra low molecular weight polyethylene consisting of ethylene monomer chains. PE wax has a large variety of uses and applications. PE Wax is available from on-purpose production and as a byproduct of polyethylene production. This material is available in both HDPE and LDPE forms. As there are many grades and types available, please inquire so that one of our knowledgeable representatives can assist you in locating the correct grade that matches your requirements.
How is polyethylene wax made?
There are a variety of methods for producing Polyethylene wax. Polyethylene wax can be made by direct polymerization of ethylene under special conditions that control molecular weight. Another method involves breaking down high molecular weight polyethylene into lower molecular weight fractions. A third method involves separation of the low molecular weight fraction from high molecular weight polymer.
Differences between polyethylene waxes type
There are three major characteristics that differentiate one PE wax from another. They are I) Molecular weight, II) Degree and length of polymer branching, III) Monomer / polymer composition. Changing any of these factors will alter the physical characteristics of the polyethylene wax, such as viscosity, hardness, melt point, reactivity etc.
Differences between PE wax and paraffin wax
Paraffin wax is usually produced as a by-product of oil refining. It has a molecular weight which is usually less than half that of most polyethylene waxes. Because of this and other differences, paraffin wax usually has a much lower melt point and is softer than most polyethylene waxes.
Polyethylene wax application
Polyethylene waxes have very unique polymer properties that make them useful in many applications. The major functions of PE wax in many formulations are to either provide lubrication and/or provide physical modification of a formula by changing viscosity and / or melt point.
Polyethylene wax increase inorganic and organic pigment dispersion in
matrix polymer during masterbach processing. Also, PE wax helps granule produce by decrease softening point of system.
Polyethylene wax is very good external lubricant for PVC. When PE wax use in PVC application, final produce face has been shine.
Polyethylene wax using decrease the friction so increase the extrusion capacity.
Polyethylene wax using doesn’t change the product color because PE wax has got good oxidation resistance.
Polyethylene wax doesn’t bad effect product’s heat and light stability because pe wax doesn’t include catalizors remnant.
Polyethylene wax increase last product’s light stability.
Polyethylene wax hasn’t got toxic materials so PE wax can be use food packaging applications.
Polyethylene wax use hot melt application.
