Is Fischer-Tropsch wax the same as PE wax

Definition of polyethylene wax

Polyethylene wax (PE wax), also known as polymer wax, is abbreviated as polyethylene wax. Due to its excellent cold resistance, heat resistance, chemical resistance, and wear resistance, it has been widely used. In normal production, this wax can be directly added to polyolefin processing as an additive, which can increase the luster and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyethylene wax, ethylene propylene rubber, and butyl rubber. It can improve the flowability of polyethylene, polypropylene, and ABS, as well as the demolding properties of polymethyl methacrylate and polycarbonate. Compared to PVC and other external lubricants, polyethylene wax also has a stronger internal lubrication effect.

  1. Definition of Fischer Wax

Fischer Tropsch wax is a methylene polymer that is an alkane synthesized from synthetic gas or natural gas. High melting point (generally higher than 85) Fischer Tropsch wax is mainly composed of linear, saturated high carbon alkanes with a relative molecular weight between 500 and 1000, which endows this chemical with a fine crystal structure, high melting point, narrow melting range, low oil content, low penetration, low mobility, low melt viscosity, hardness, wear resistance, and high stability.

  1. Comparison of Performance between Polyethylene Wax (PE Wax) and Fischer Wax

a. The commonality between Fischer Wax and PE Wax. As the addition amount increases, the compatibility between the two and PVC resin changes. In small amounts, it can be used as a good internal lubricant to effectively control shear conditions, promote flow, control friction and melting properties, and thereby improve thermal stability. As the addition amount increases and the shear temperature increases, the lubricant gradually migrates to the surface of the PVC melt, reducing friction and debonding between the melt and the metal surface, preventing local overheating and decomposition, and also increasing product luster.

b. The difference between Fischer Tropsch wax and PE wax (a). The molecular structure of PE wax is low molecular weight polyethylene, and the molecular weight is generally 2000-5000. The PE wax on the market is mainly cracking wax and synthetic wax. The molecular weight of Fischer Tropsch synthetic wax is generally 500-1000 linear, saturated alkanes, therefore, Fischer Tropsch wax has a high crystallinity and high linearity structure. (b) The viscosity of Fischer Tropsch wax and PE wax differs greatly due to their different molecular structures.

  1. Purpose and Industry

1. Thick color masterbatches and filling masterbatches are widely used as dispersants in the processing of color masterbatches for polyolefins. It has good compatibility with resins such as polyethylene, polyvinyl chloride, and polypropylene, and has excellent external and internal lubrication effects.

2. PVC profiles, pipes, and composite stabilizers are used as dispersants, lubricants, and brighteners in the molding process of PVC profiles, pipes, pipe fittings, and PE. PP to enhance the degree of plasticization, improve the toughness and surface smoothness of plastic products, and are widely used in the production of PVC composite stabilizers.

3. Ink has good light resistance and chemical properties, and can be used as a carrier for pigments. It can improve the wear resistance of paints and inks, improve the dispersion of pigments and fillers, and have a good anti settling effect. It can be used as a leveling agent for paints and inks, making products have good luster and three-dimensional feeling.

Wax products are widely used in the production of various wax products such as floor wax, car wax, polishing wax, candles, crayons, etc., to improve the softening point of wax products, increase their strength and surface glossiness.

5. Cable material is used as a lubricant for cable insulation materials, which can enhance the diffusion of fillers, improve extrusion molding rate, increase mold flow rate, and facilitate demolding.

6. Hot melt products are used as dispersants for various types of hot melt adhesives, thermosetting powder coatings, road marking paint, and marking paint, with good anti settling effect and giving the products good luster and three-dimensional feeling.

As a rubber processing aid, 7 rubber can enhance the diffusion of fillers, increase extrusion molding rate, increase mold flow rate, facilitate demolding, and improve the surface brightness and smoothness of the product after demolding.

8. Cosmetics give products a good gloss and three-dimensional feel.

9. Injection molding saves machine power and lubricates, enhancing the surface glossiness of products.
