The Amount Of Fischer-Tropsch Wax Added To Masterbatch

The amount of Fischer-Tropsch wax added to masterbatch. Fischer-Tropsch wax has a wide range of applications due to its high melting point, hardness and good chemical inertness. The good dispersion and wetting properties of Fischer-Tropsch wax itself play a vital role in the processing of plastic products.

Application of Fischer-Tropsch wax in masterbatch:

Fischer-Tropsch wax has low compatibility with polymers. It is easy to migrate from the inside of the polymer to the surface during processing, and oriented at the interface to form a lubricant molecule layer through physical adsorption, which can reduce the friction between the polymer and the equipment surface and prevent it from adhering to the mechanical surface, thereby improving the flow performance.

Fischer-Tropsch wax has a certain solubility with polymers, and its compatibility increases at high temperatures, producing a plasticizing effect, weakening the cohesion between polymer molecules, reducing internal friction, reducing body viscosity and increasing fluidity.

Fischer-Tropsch wax has a small molecular weight and low kinematic viscosity, so it has good wetting properties for inorganic pigment particles, can weaken the van der Waals force between particles, reduce the probability of particle collision, and thus improve the dispersion effect of pigments. The higher hardness of Fischer-Tropsch wax will also improve the anti-friction effect of masterbatch.

However, due to the small molecular weight and low kinematic viscosity of Fischer-Tropsch wax, it focuses on external slip, and the use ratio is not easy to grasp. Wax is easy to agglomerate and precipitate under strong shear force. Therefore, in order to improve the application effect of Fischer-Tropsch wax, we generally need to upgrade the refined Fischer-Tropsch wax to meet the requirements of different customers for product processing performance. Different masterbatch Fischer-Tropsch modified products solve the problems of poor compatibility, low kinematic viscosity, easy precipitation, insufficient brightness, and insufficient anti-friction force.
