Can Fischer-Tropsch wax replace polyvinyl wax? Fischer-Tropsch wax is mainly composed of straight-chain, saturated high-carbon alkanes with a relative molecular mass of 500-1000, which endows this chemical with a fine crystal structure, high melting point, narrow melting point range, low oil content, low needle High strength, low mobility, low melt viscosity, hardness, wear resistance and high stability.
Compared with general-purpose polyethylene wax (PE wax), the significant differences between Fischer-Tropsch synthetic wax and common polyethylene wax are:
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. The lubrication effect is obvious.
2. Fischer-Tropsch wax is a saturated direct-connected alkane, does not contain double bonds, has strong antioxidant ability, and the product has good weather resistance.
3. The viscosity of Fischer-Tropsch wax is much lower than that of PE wax, only about 10. The same lubricating effect can be achieved with less amount. The amount used is only 70-80% of that of PE wax.
Fischer-Tropsch wax(FT 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.
Can Fischer-Tropsch wax replace polyvinyl wax? Polyethylene wax has stronger internal lubrication and is widely used in the manufacture of colored granules, granulation, plastic steel, PVC pipes, hot melt adhesives, rubber, shoe polish, leather brighteners, cable insulation materials, and floor waxes. , plastic profiles, inks, injection molding and other products.
