The Difference Between Microcrystalline Wax & Polyethylene Wax(PE Wax)

The difference between microcrystalline wax and polyolefin wax. Polyethylene wax (PE wax) is also called polymer wax or polyolefin wax. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and abrasion resistance.

Microcrystalline wax is a refined synthetic wax with similar microcrystalline properties. It has the characteristics of good luster, high melting point and light color. It has a tight structure, is strong and smooth, can melt with various natural waxes, and can improve its Lowers the melting point of waxes, improving the performance of coarse waxes. Microcrystalline wax itself is as white as stone and shines when rubbed, which has a very beneficial effect on the production of light-colored products. In terms of color, microcrystalline wax is creamy white or light yellow.

Polyethylene wax(PE Wax) is generally divided into four types: oligomer wax, cracking wax, polymer wax and blending wax. Domestically produced wax is generally oligomer wax, while other cracking wax, polymer wax and blending wax are mainly produced abroad. In theory, the performance of polymerized wax is better than that of cracked wax. The specific use depends on the compatibility of the product. It is generally used to improve the fluidity of polyolefin plastics, improve the dispersion of fillers and additives, and is also used as an internal lubricant for rubber and plastic materials.

Polyethylene wax has good compatibility with polyolefin, polypropylene, polyolefin, propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene, and ABS and the mold release of polymethylmethacrylate and polycarbonate. Compared with PV and other external lubricants, polyethylene wax also has stronger internal lubrication.
