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 excellent lubrication properties. It is widely used in industrial production. For example, in the injection molding, extrusion and granulation industries, Fischer-Tropsch wax helps to disperse fillers and improve slippery properties during mixing during the production of colored granules and modified plastics.

Fischer-Tropsch wax can be used as an external lubricant for PVC. Its low viscosity can increase the production speed of the product. It helps in the dispersion of pigments and fillers during mixing, especially in the extrusion of high-viscosity systems. The addition amount 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. It is mainly used as a lubricant to lubricate. Compared with lubricants such as paraffin wax and polyolefin wax, Fischer-Tropsch wax has a high melting point (generally higher than 85°C). ), narrow melting point range, low oil content, low needle penetration, low mobility, very low melt viscosity, high stability, hardness, and wear resistance. It can provide long-term and highly stable lubrication effect at a low adding amount. Effectively reduce processing torque, reduce production energy consumption, and improve production efficiency. The degree of aging resistance and surface material properties of the product 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 enables PVC products to obtain the best physical and processing properties due to its high crystallinity and high linearity structure. According to needs, the Fischer-Tropsch process can synthesize alkanes of different chain lengths to change the molecular size of the final product to form a series of products.
