KUNLUN#58 Fully Refined Paraffin Wax

In industrial applications, it is often useful to modify the crystal properties of the Paraffin Wax, typically by adding branching to the existing carbon backbone chain. The modification is usually done with additives, such as EVA copolymers, microcrystalline wax, or forms of polyethylene. The branched properties result in a modified paraffin with a higher viscosity, smaller crystalline structure, and modified functional properties. Pure paraffin wax is rarely used for carving original models for casting metal and other materials in the lost wax process, as it is relatively brittle at room temperature and presents the risks of chipping and breakage when worked. Soft and pliable waxes, like beeswax, may be preferred for such sculpture, but "investment casting waxes," often paraffin-based, are expressly formulated for the purpose.

In a histology or pathology laboratory, paraffin wax is used to impregnate tissue prior to sectioning thin samples of tissue. Water is removed from the tissue through ascending strengths of alcohol (75% to absolute) and the tissue is cleared in an organic solvent such as xylene. The tissue is then placed in paraffin wax for a number of hours and then set in a mold with wax to cool and solidify; sections are then cut on a microtome.

Melting Point
Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point as pure compounds. The so-called melting point of paraffin refers to the temperature at which the first stagnation period occurs on the cooling curve when the melted paraffin sample is cooled under the specified conditions. All kinds of wax products require wax to have good temperature resistance, that is, it will not melt or soften at a certain temperature. Commercial paraffin is required to have a series of different melting points according to the differences in use conditions, use regions and seasons and use environment.

The main factor affecting the melting point of paraffin is the weight of the selected raw material fraction, and the melting point of the paraffin extracted from the heavier fraction is higher. In addition, the oil content also has a great influence on the melting point of paraffin. The more oil in paraffin, the lower its melting point.

Oil Content
Oil content refers to the amount of low melting point hydrocarbons contained in paraffin. Too high oil content will affect the color and storage stability of paraffin, and also reduce its hardness. Therefore, the oily wax paste extracted from the vacuum fraction needs to be deoiled by sweating method or solvent method to reduce its oil content. However, most paraffin products need to contain a small amount of oil, which is beneficial to improve the gloss and demoulding performance of the products.

Light Stability
In the process of modeling or coating, paraffin products are in hot-melt state for a long time and are in contact with the air. If the stability is not good, it is easy to oxidize and deteriorate, the color becomes dark, and even gives off a bad smell. In addition, the paraffin wax will turn yellow under light conditions when used. Therefore, paraffin wax is required to have good thermal stability, oxidation stability and light stability.

The main factors affecting the stability of paraffin are the trace non hydrocarbon compounds and polycyclic aromatic hydrocarbons. In order to improve the stability of paraffin, deep refining of paraffin is needed to remove these impurities.

Needle penetration
Needle penetration refers to the depth of the standard cone (generally with a total load of 150 g, but also with a specified load of 100 g) sinking into the grease sample at 25 ℃ within 5 seconds. The unit is 1 / 10 mm. The greater the penetration, the softer the grease, that is, the smaller the consistency; On the contrary, it means that the harder the grease, the greater the consistency. The penetration of asphalt is measured by using a standard needle with a total load of 100g instead of a standard cone. The measurement conditions are the same as those of lubricating grease.
