Microcrystalline waxes

Microcrystalline wax is a strong but not permanent hold, it is water proof, ( remember those Roman boat builders ) it is a great gap filler, adheres instantly and is not toxic unless it is burned. This adhesive wax has many uses. It works on any material, porous or non porous. It is acid free and will not wrinkle fine papers. It is great for sticking irregular organic objects such as rocks and seashells. It softens in heat which makes it easy to work with these hot summer days (but remember not to leave your work out in direct sunlight, or it may just melt away completely). Microcrystalline Wax is also good to use as a clamp to hold two difficult to clamp objects together, while you wait for a more permanent adhesive to cure, such as silicone or epoxy.

Microcrystalline waxes are excellent materials to use when modifying the crystalline properties of paraffin wax. The microcrystalline wax has a significant effect on the branching of the carbon chains that are the backbone of paraffin wax. This is useful when some desired functional changes in the paraffin are needed, such as flexibility, higher melt point, and increased opacity. They are also used as slip agents in printing ink.

Microcrystalline wax is often used in industries such as the tire and rubber, candles, adhesives, corrugated board, cosmetics, castings, and a host of others. Refineries may also utlize blending facilities to combine paraffin and microcrystalline waxes. This type of activity is prevalent especially for industries such as tire and rubber.

Microcrystalline waxes are a type of wax produced by de-oiling petrolatum, as part of the petroleum refining process. In contrast to the more familiar paraffin wax which contains mostly unbranched alkanes, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons. It is characterized by the fineness of its crystals in contrast to the larger crystal of paraffin wax. It consists of high molecular weight saturated aliphatic hydrocarbons. It is generally darker, more viscous, denser, tackier and more elastic than paraffin waxes, and has a higher molecular weight and melting point. The elastic and adhesive characteristics of microcrystalline waxes are related to the non-straight chain components which they contain. Typical microcrystalline wax crystal structure is small and thin, making them more flexible than paraffin wax. It is commonly used in cosmetic formulations. Industries and Applications
