3 differences between FT waxes and PE waxes

2021-06-20   Pageview:398

The significant differences between Fischer-Tropsch synthetic waxes and polyethylene waxes (PE waxes) are:

1, Molecular weight. The molecular weight of Fischer-Tropsch wax is much lower than that of PE wax, and the branched chain is also less, with high crystallinity, which is easy to penetrate into the high-viscosity macromolecular chain and significantly reduce the melt viscosity, with little migration during processing and obvious lubricating effect in the later stage.

2, Fischer-Tropsch wax is saturated direct alkane, does not contain double bond, strong antioxidant ability, good weather resistance.

3, Viscosity of Fischer-Tropsch wax is much lower than PE wax. It is only about 10. The same lubricating effect can be achieved with less dosage. The use amount is only 70-80% of PE wax. Fischer-Tropsch wax is more compatible with PVC and can be competent as both internal and external lubricant. It can be used as a good internal lubricant to effectively control shear conditions, promote flow, control friction and melt properties, thus improving thermal stability.

Fischer-Tropsch waxes give the best physical and processing properties to PVC products due to their high crystallinity and linearity structure. Depending on the need, Fischer-Tropsch process can synthesize alkanes of different chain lengths to change the molecular weight of the final product and form a series of products.
