What is paraffin?
Paraffin is also called the wax crystal shape, usually white, colorless, odorless waxy solid, melting in 47 ° C to 64 ° C, the density is about 0.9 g/cm3.It is insoluble in water, but soluble in ether, benzene and certain esters.
Pure paraffin is a good insulator with a resistivity of 1013-1017 ohm meters, which is higher than most materials except some plastics (especially teflon).
Paraffin is also a good heat storage material, and its specific heat capacity is 2.14-2.9J·g - 1·K - 1, and the melting heat is 200-220J·g - 1.Paraffin wax is the main component of a candle.
Paraffin is a hydrocarbon mixture of about 18 to 30 carbon atoms.According to the melting point, every 2 ℃, usually divided into different varieties, such as 52, 54, 56, 58.According to the different refining degree, it can be divided into whole refined paraffin, semi-refined paraffin and crude paraffin.
What is polyethylene wax?
Polyethylene wax, or low molecular weight polyethylene, although it has a "wax" in its name, is not actually "waxy", but a low molecular polyethylene, a polymer.
Polyethylene wax is widely used in coatings for low molecular weight polyethylene homopolymer or copolymer.The so-called wax, which means that the polymer ends up with a microcrystalline form of floating cloth that ACTS like paraffin in the surface of the paint but is much more varied and practical than paraffin wax.
The main functions of polyethylene wax in solvent coating film are: extinction, anti-scratch, anti-wear-resisting, anti-polishing, anti-imprinting, anti-adhesion, anti-deposition and thixotropy;Good lubricity and machinability;Metallic pigment localization.
