PE wax

Polyethylene Wax


made of ethylene monomer chains with (C2H4)n chemical formula .

(LDPE )low molecular weight polyethylene polymer and (HDPE) high molecular weight polyethylene polymer are famous grades of this product which because of  molecular weight it will have different appearance such as viscosity, hardness, melt point, reactivity etc.
PE Wax a byproduct of polyethylene producing.

different kinds of Polyethylene 


Main grades are based on :

1- Low molecular weight polyethylene polymer (LDPE ) and  high molecular weight polyethylene polymer (HDPE)

 2- Polymers can have side chains and branches spreading  from one main chain . Side chains or branches comes out of the same units as the main polymer chains. The branches are built by side reactions during polymerization.

The length of the side chains or branches is different : long- or short-branched polymers. Long branches are comb-like, random, or star-shaped . However, they do not connect to another polymer chain.

3-Monomer / polymer Monomers with two or more end groups are likely to support branching. For a polymer to classify as branched polymer the side chains or branches must comprise of a minimum of one complete monomer unit.

Oxidized  PE wax


Homopolymer polyethylene wax will be functionalized by oxidation and  adds acid and ester  to the polyethylene wax. Oxidized polyethylene wax is polar and has different compatibility properties that polyethylene homo polymer. This functionality results  emulsification of oxidized polyethylene wax.

different between Pe wax and paraffin wax


Paraffin wax is produced as a by-product of oil refining. It has a molecular weight which is usually less than half that of most PE waxes. So, paraffin wax usually has a  lower melting  point and is softer than PE wax.

  Forms


It can be formed in flakes, granulated or powder  which are in different sizes too.

 Applications  


It is used in  films, tubes, plastic parts, laminates, packaging, automotive, electrical, tire , master batch , creams , body lotions etc.

Packing 


 is usually 25 kg bags or jumbo bags .
