The difference between polyolefin wax and Fischer-Tropsch wax is that Fischer-Tropsch wax is a methylene polymer, which is an alkane polymer synthesized from hydrocarbon-based synthetic gas or natural gas. It mainly relies on high-quality and cheap raw materials from coal chemical industry for iron-based or cobalt Synthetic based, which has a clear advantage over crude oil prices.
Polyethylene wax (PE wax), also known as polymer wax, is referred to as polyolefin wax. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and abrasion resistance. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber, and butyl rubber, and can improve the fluidity of polyethylene, polypropylene, and ABS and polymethyl methacrylate, polycarbonate Release properties of esters. Compared with PVC and other external lubricants, polyvinyl wax has stronger internal lubrication.
Fischer-Tropsch synthesis has received intermittent attention as a source of low-sulfur diesel fuel to address supply or cost issues with petroleum-based hydrocarbons.
The key technology of Fischer-Tropsch wax(FT Wax) production lies in the catalyst, commonly used catalysts are iron-based catalysts and cobalt-based catalysts. Iron-based catalysts are mainly used to produce Fischer-Tropsch waxes with a drop melting point below 105°C, and only cobalt-based catalysts can be used for Fischer-Tropsch waxes with higher melting points. The appearance and performance of Fischer-Tropsch wax produced by cobalt-based catalysts are better than those produced by iron-based catalysts.
Fischer-Tropsch wax(FT Wax) has good compatibility with PVC and can be used as an internal and external lubricant. Acts as a good internal lubricant to effectively control shear conditions, facilitate flow, control friction and melting properties, thereby improving thermal stability. At the same time, due to its high crystallinity and high linearity structure, Fischer-Tropsch wax enables PVC products to obtain the best physical and processing properties.
