The difference between stearic acid, PE wax and paraffin

      Stearic acid, i.e. octadecanoic acid, is produced by hydrolysis of oils and fats. The key is to produce polyether salts. The melting point is 69.6 ℃, which is a main component of animal and grease. State: the pure product is white crystalline small crystals with a little gloss. Melting point: 71.5-72 ℃, 69.6 ℃, melting point: 232 ℃ (2.5kpa), open flash point: 220.6 ℃   self ignition point: 444.3 ℃, reliability: 360 ℃ dissolution (another material says 376.1 ℃); toxic and side effects: non toxic dissolution status: insoluble in water (at 20 ℃, only 0.00029g is dissolved in 200ml of water). Slightly dissolve the cold alcohol. Dissolve toluene, benzene, medical ether, chloroform, carbon tetrachloride, sulfur dioxide, chloroform, hot alcohol, xylene, amyl glacial acetate, etc. Others: gradually evaporate at 90-100 ℃. Have the basic laws of organic chemistry of carboxyl group in general organic chemistry.

      PE wax is polyethylene wax, which is generally divided into oligomer wax, cracking wax, aggregation wax and blending wax. Oligomer wax is widely produced and manufactured in China. Other cracking waxes, aggregation wax and blending wax are mainly produced and manufactured overseas. Theoretically, the performance of aggregation wax is better than cracking wax. The actual application depends on the compatibility of the products. It is generally used to improve the flowability of isoprene rubber plastics, improve the dispersion of fillers and modifiers, and is also used as an internal lubricant for raw materials of rubber and plastic products. Main features: low viscosity, high softening point, good strength, non-toxic, good heat resistance, low volatile matter at high temperature, dispersibility to color paste, not only excellent external wettability, but also strong internal wetting effect, which can improve the productivity of plastic granulation, good moisture resistance under normal temperature, strong chemical resistance, high electrical performance, and can improve the appearance of finished products. Because of its excellent external moisturizing effect and strong internal moisturizing effect, and good compatibility with high-pressure polyethylene, polyethylene, polypropylene and other epoxy resins, it can be used as a lubricant in extrusion, injection molding, injection production and processing. It can improve the production and processing efficiency, avoid and get rid of the adhesion of plastic film, pipe fittings and plastic plates, improve the smoothness and smoothness of finished products, and improve the appearance of finished products. As a thickener of thick color masterbatch of various thermoplastic plastics and a wetting thickener of plastic filling masterbatch and dissolving masterbatch, it can improve the production and processing performance, surface gloss, wettability and heat resistance of HDPE, PP and PVC. As the lubricant of the insulation layer material of the cable, it can improve the spread of the filler, improve the extrusion processing speed, expand the total flow of the die shell, and make the die exit convenient. It has good light resistance and organic chemical properties. It can be used as the medium of color paste, improve the wear resistance of paint and printing ink, improve the dispersion of color paste and filler, and avoid the color paste from sinking. It can be used as the Hongchen agent of paint and printing ink. Can be added to a variety of paraffin to improve its performance. The high-quality electrical conductor and insulator performance can be added to transformer oil, paraffin or nano microcrystalline paraffin to make it soft, increase the temperature, improve the viscosity and insulation layer performance. It can be used as the waterproof coating for cable insulation layer, power capacitor and transformer winding. It can be widely used in the production of plastic masterbatch, granulation, plastic steel profile, PVC pipe, thermosol, vulcanized rubber, leather shoe oil, leather product polishing liquid, cable edge material, automobile wax, plastic aluminum profile, printing ink, injection molding and other commodities.

     Paraffin is a kind of strange wax obtained from crude oil, shale oil or other mineral oil. It is white or light yellow transparent and has a very significant molecular structure.

     Paraffin is a kind of mineral wax and crude oil wax; It is a block or fibrous crystal obtained from the vacuum residue of lubricating grease obtained by petroleum steam distillation, which is specially prepared by organic solvent, solvent dewaxing, or cold storage crystallization of wax, extraction and dewaxing to make wax paste, and then acid removal by organic solvent. It is also called crystalline wax. The key quality standards are the melting point and oil content. The former indicates the high-temperature working ability, and the latter indicates the purity.
