#Polyethylene wax (also known as #PE wax) is a low molecular-weight polyethene polymer that because of its low molecular weight has wax-like physical characteristics.
There are a variety of methods for producing Polyethylene wax. Polyethene wax can be made by direct polymerization of ethylene under special conditions that control molecular weight. Another method involves breaking down high molecular-weight polyethene into lower molecular-weight fractions. A third method involves the separation of the low molecular weight fraction from the high molecular weight polymer.
There are three major characteristics that differentiate one polyethene 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 polyethene wax, such as viscosity, hardness, melt point, reactivity etc.
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 polyethene waxes. Because of this and other differences, paraffin wax usually has a much lower melt point and is softer than most polyethene waxes.
Polyethene waxes can be supplied in many forms. They can be supplied in bulk with the use of speciality bulk trailers that are heated. Polyethene wax can be finished as a prill or atomized powder. Polyethene waxes can also be ground into various particle sizes. Harder waxes are usually easier and less costly to grind than softer waxes.
Polyethene waxes have very unique polymer properties that make them useful in many applications. The major functions of polyethene wax in many formulations are to either provide lubrication and/or provide physical modification of a formula by changing viscosity and/or melting point.
