The Role Of Fischer-Tropsch Wax(FT Wax) In PVC

The role of Fischer-Tropsch wax in PVC. Fischer-Tropsch synthetic wax is a high molecular inert substance with low viscosity, high softening point, high melting point and other characteristics. It has excellent lubrication performance and is widely used in industrial production. For example, in the injection molding, extrusion and granulation industries, Fischer-Tropsch wax helps to disperse fillers and has excellent smoothness during mixing in the production process of masterbatch and modified plastics.

Fischer-Tropsch wax can be used as an external lubricant for PVC. Low viscosity can increase the production speed of the product. It helps to disperse the color fillers during mixing, especially in the extrusion of high viscosity systems. The amount of addition is 40%-50% less than that of ordinary PE wax, and it can significantly improve the surface gloss of the product.
Fischer-Tropsch wax is used in PVC composite stabilizers, mainly as a lubricant, which plays a lubricating role. Compared with lubricants such as paraffin wax and polyethylene wax, Fischer-Tropsch wax has high melting point (generally higher than 85°C), narrow melting point range, low oil content, low penetration, low migration rate, very low melt viscosity, high stability, hardness, and wear resistance. It can provide long-term, highly stable lubrication effect at a low addition amount. It can effectively reduce processing torque, reduce production energy consumption, and improve production efficiency. The aging resistance and surface material properties of the products are significantly improved.

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, Fischer-Tropsch wax, due to its high crystallinity and high linearity structure, enables PVC products to obtain the best physical and processing properties. According to needs, the 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.
