Product Overview
Microcrystalline Wax
Microcrystalline waxes, derived from de-oiling petrolatum during the petroleum refining process, stand apart from the conventional paraffin wax due to their distinctive composition. Unlike paraffin wax, dominated by unbranched alkanes, microcrystalline wax boasts a higher proportion of iso-paraffinic (branched) hydrocarbons and naphthenic hydrocarbons.
The hallmark of microcrystalline wax lies in the refinement of its crystals, which are notably finer compared to the larger crystals found in paraffin wax. Comprising primarily high molecular weight saturated aliphatic hydrocarbons, microcrystalline wax possesses distinct characteristics: it tends to be darker in color, more viscous, denser, tackier, and exhibits greater elasticity than paraffin waxes. Additionally, it boasts a higher molecular weight and melting point, setting it apart in terms of properties and applications.
Elasticity and Adhesion in Microcrystalline Waxes
The unique elastic and adhesive properties of microcrystalline waxes stem from their composition, which includes non-straight chain components. This characteristic makes them more flexible compared to paraffin wax, allowing for various applications, particularly in cosmetic formulations.
Specifications and Grades
Microcrystalline waxes are refined to meet specific ASTM standards, ensuring quality and consistency across different grades. These standards include congeal point (ASTM D938), needle penetration (ASTM D1321), color (ASTM D6045), and viscosity (ASTM D445).
Categorization and Characteristics
Microcrystalline waxes are typically classified into two main categories: "laminating" grades and "hardening" grades. Laminating grades, with melt points ranging from 140-175°F (60-80°C) and needle penetration of 25°C or above, offer specific properties suited for certain applications. On the other hand, hardening grades, with melt points ranging from about 80-93°C and needle penetration of 25°C or below, cater to different requirements.
Production Process
Microcrystalline waxes are derived from the refining of heavy distillates obtained during lubricant oil production. This byproduct undergoes de-oiling at a wax refinery to produce microcrystalline wax. Depending on the intended use and desired specifications, additional processing steps such as Odor and color removal may be carried out using methods like filtration or hydro-treating. These processes help refine the wax further, enhancing its quality and versatility.
Packing
At Paraffin Co. microcrystalline waxes are packaged in 5 kg slabs, typically enclosed in cartons or gunny sacks for storage and transportation. Additionally, these slabs can be pelletized for efficient handling and storage, providing convenience and ease of transport for bulk quantities.
