The difference between Fischer-Tropsch wax and PE wax? Fischer-Tropsch wax is characterized by high melting point, narrow melting point range, low oil content, low penetration, low mobility, low melting viscosity, hardness, wear resistance and high stability.
Compared with general polyethylene wax (PE wax), Fischer-Tropsch synthetic wax differs significantly in that:

(1) Molecular weight. The molecular weight of Fischer-Tropsch wax is much lower than that of PE wax, with fewer branched chains and high crystallinity. It is easy to penetrate into high viscosity macromolecular chains, significantly reducing melt viscosity, small migration in the processing process, and obvious lubrication effect in the later stage.

(2) Fischer-Tropsch wax is a saturated direct paraffin with no double bond, strong antioxidant ability and good weather resistance.

(3) Viscosity of Fischer-Tropsch wax is much lower than that of PE wax, only about 10 percent. The same lubrication effect can be achieved with a small amount of use, which is only 70-80 percent of PE wax. Fischer-Tropsch wax has good compatibility with PVC and can be used as both internal and external lubricants. It can be used as a good internal lubricant to effectively control shear conditions, promote flow, control friction and melting properties, thereby improving thermal stability. At the same time, because of its high crystallinity and high linearity structure, Fischer-Tropsch wax can obtain the best physical and processing properties of PVC products. According to the need, Fischer-Tropsch process can synthesize alkanes with different chain lengths, change the molecular weight of the final product, and form a series of products.
