Petroleum Waxes for Industrial, Packaging, and Specialty Applications
Petroleum waxes are refined hydrocarbon-based materials derived from crude oil processing. Depending on the refining method and degree of purification, they range from soft, pliable forms with high oil content to hard, fully refined grades with precise melting points and low impurities, each suited to different performance requirements.
IGI offers a comprehensive range of petroleum-derived waxes, including paraffin wax, microcrystalline wax, and slack wax to clients across multiple industries. Engineered for reliability, consistency, and regulatory compliance, our waxes are designed to meet the critical performance and quality standards of industrial, packaging, food, and specialty sectors. Each petroleum wax grade is supported by transparent technical data and the insight of a knowledgeable engineering team.
How Petroleum Waxes Are Produced and What Determines Their Properties
Petroleum waxes are derived from crude oil through a series of refining stages. The process begins during vacuum distillation, when heavy hydrocarbon fractions are separated from crude oil. These fractions are then processed through solvent dewaxing, which isolates the waxy components from the lubricating oil base stocks. The resulting material, known as slack wax, contains varying levels of residual oil and serves as the feedstock for further refining.
From there, additional processing steps, including hydrotreating, deoiling, and filtration, determine the final grade. Fully refined paraffin waxes undergo more extensive processing to reduce oil content and achieve a consistent, white appearance. Microcrystalline waxes, derived from heavier distillate fractions, retain a finer crystal structure and higher molecular weight, which gives them distinct physical properties compared to paraffin grades.
Several key characteristics vary across petroleum wax types and directly influence their suitability for a given application:
- Melt point: Measured in °C or °F, melt point determines thermal stability and processing temperature requirements. Higher melt point grades are typically used in industrial coatings and applications requiring heat resistance.
- Oil content: The percentage of residual oil affects flexibility, tackiness, and surface finish. Slack waxes carry higher oil content, while fully refined grades are formulated to minimize it.
- Crystal structure: Paraffin waxes form larger, more defined crystals; microcrystalline waxes have a finer, more amorphous structure that contributes to greater flexibility and adhesion.
- Hardness and viscosity: These properties affect how a wax performs during processing and in the final application, whether as a coating, additive, or base material.
Understanding these variables is the starting point for selecting the right petroleum wax grade for your process and performance requirements.
Technical Overview of Petroleum Wax Grades
IGI’s petroleum waxes are refined and fractionated to deliver the required physical and chemical properties necessary for an array of applications.
Paraffin Waxes
Our paraffin waxes are characterized by high crystallinity, clarity, and controllable melting points, making them the ideal wax for packaging products, candles, and more. Many are also FDA-approved for use in food coatings.
Microcrystalline Waxes
Microcrystalline wax offers higher flexibility, adhesion, and oil retention than other wax types. Our microcrystalline waxes are ideally suited for cosmetics, adhesives, rubbers, and electrical applications.
Slack Waxes
Slack wax finds use as an intermediate or base material for industrial lubricants, protective coatings, and formulation extenders.

Frequently Asked Technical Questions
Q: What is the difference between paraffin, microcrystalline, and slack wax?
A: Paraffin wax is highly crystalline and transparent, and is used for clarity, barrier, and melt-point control. Microcrystalline wax is more flexible, adhesive, and oil-retentive, making it ideal for formulations needing enhanced elasticity or texture. Slack wax is a less refined intermediate wax typically used as a base or for blending.
Q: Are IGI petroleum waxes food or pharma grade?
A: Select IGI paraffin and microcrystalline wax grades are FDA-compliant for direct or indirect food contact. Some of our petroleum waxes are also pharmaceutical grade. Always specify the intended use and request regulatory documentation for food or pharmaceutical applications before ordering.
Q: Can you match a competitor’s wax or develop a custom blend?
A: Yes. Please provide a target specification or competitor data sheet and our expert IGI engineers will match, formulate, or improve upon the reference to create a bespoke wax for your needs.
Q: How do you ensure product quality and batch-to-batch consistency?
A: Every batch of IGI petroleum wax is tested for melting point, oil content, color, and penetration, with full traceability assured and COA/SDS documentation retained and supplied with every order.
Q: What formats and packaging options are available?
A: All our waxes are available as standard slabs or in pelletized, bagged, or bulk formats. Packaging can also be customized for line compatibility or storage needs. Please reach out to the team to discuss your requirements.
Q: What are the types of petroleum wax?
A: Petroleum wax types refer to the range of wax materials derived from crude oil refining, each with distinct properties and applications. The main types are paraffin wax, microcrystalline wax, and slack wax. Paraffin wax is highly crystalline and used in packaging, candles, and food coatings. Microcrystalline wax has a finer crystal structure and is valued for its flexibility and adhesion in cosmetics, adhesives, and rubber applications. Slack wax is a less refined intermediate grade commonly used as a base material or blending component in industrial formulations.
Q: Is paraffin wax a petroleum product?
A: Yes. Paraffin wax is a petroleum product derived from crude oil refining. It is separated from lubricating oil base stocks through a process called solvent dewaxing and then further refined to achieve the purity, melt point, and color specifications required for industrial, food-contact, and specialty applications.
Q: What is the minimum order quantity for petroleum wax grades?
A: Minimum order quantities vary by grade and format. Bulk liquid orders have different thresholds than slab or pelletized formats. Contact our team with your required grade and packaging preference, and we will confirm availability and MOQ for your specific needs.
Q: How should petroleum waxes be stored to maintain their properties?
A: Petroleum waxes should be stored in a cool, dry environment away from direct heat sources and open flame. Solid grades should be kept in their original packaging until use to prevent contamination. Specific storage conditions, including recommended temperature ranges, are outlined in the SDS provided with every order.
Q: Can petroleum waxes be used in combination with natural or plant-derived waxes?
A: Yes. Petroleum waxes are frequently blended with natural waxes to achieve specific performance targets, such as adjusting melt point, improving flexibility, or modifying texture. IGI’s blending capabilities enable formulations that combine petroleum- and plant-derived wax components to meet both technical and sustainability requirements.
