The name "waxes" covers a wide group of organic substances of natural or synthetic origin. Synthetic waxes are divided into fully synthetic and semi-synthetic waxes. An example of a synthetic wax is polyethylene wax or briefly PE Wax. PE Waxes are low molecular weight polymer of the Ethylene and sometimes have other alpha olefins as co-monomer. PE Waxes generally have molecular weight of 10,000 Mn. or less and exhibit wax like properties. Polyethylene waxes are manufactured by one of three methods:
1- Direct polymerization of ethylene (may include co -monomers such as alpha olefins, vinyl acetate, acrylic acid …)
2- Thermal degradation of high molecular weight polyethylene resin
3- Refining of Low Polymer Wax (low molecular weight fractions) from high molecular weight polyethylene resin production.
The stream of material that is recovered from high density polyethylene resin plants and is use as a feed-stock for refining operations is generally called Low Polymer Wax. Polyethylene wax manufactured by recovery of Low Polymer Wax and subsequent removal of volatile components and residual catalyst are called Refined Polyethylene Waxes.
PE Wax which we supply is Refined Polyethylene Wax from low pressure polymerization of HDPE with the following specifications:
