What is Paraffin Wax CAS 8002-74-2?

Paraffin Wax CAS 8002-74-2 is a petroleum-derived mixture of saturated straight-chain hydrocarbons, commonly represented by the general formula CnH2n+2 with carbon chains mainly in the C20-C40 range. It is a white to off-white crystalline solid supplied as slabs, pellets, or granules and is practically insoluble in water.

What is the difference between fully refined and semi-refined paraffin wax?

Fully refined paraffin wax has a low oil content, typically not more than about 0.5%, along with better color, odor, and purity, making it suitable for food-contact packaging, cosmetics, and demanding candle or coating uses. Semi-refined wax is more economical, with oil content generally around 1.5-2.0%, and is selected where slightly less stringent color and odor performance is acceptable.

Which industrial applications commonly use Paraffin Wax CAS 8002-74-2?

It is widely used in candle making, waterproof paper and packaging coatings, polishes, rubber and plastic processing aids, electrical insulation, and textile or leather finishing. The selected melting range and oil content are matched to the required hardness, gloss, barrier property, and processing temperature.

How should the melting point and storage conditions be selected for Paraffin Wax?

The melting range should be chosen from the product specification to match the end-use temperature and hardness; this page lists a customizable range around 54-64 degrees C, while a typical 58-60 degrees C grade is common for many candle and packaging applications. Paraffin wax should be stored in closed containers in a cool, dry, ventilated area below about 45 degrees C, away from heat, open flames, and strong oxidizers.

Paraffin Wax CAS 8002-74-2

Paraffin Wax is a solid, colorless or white crystalline mixture of straight-chain hydrocarbons categorized under Industrial & Specialty Chemicals, functioning as a critical hydrophobic agent and thermal energy storage medium. This petroleum-derived substance is characterized by its distinct melting point range and low oil content, which dictates its structural hardness and barrier efficiency when applied to various substrates. Within industrial manufacturing, it serves as a fundamental lubricant and release agent in the production of rubber auxiliaries and plastic additives, where it prevents adhesion and improves the surface finish of molded components. Its high dielectric strength also renders it an essential component for electrical insulation and moisture-proofing in the electronics and paper industries. We provide this versatile hydrocarbon material with competitive factory pricing to support international manufacturing sectors, offering customized specifications for various oil content levels and melting points ranging from 54°C to 64°C. Each consignment is rigorously tested and accompanied by MSDS, TDS, COA to ensure compliance with purity and safety standards for bulk supply to global industrial markets.

Applications

Paper & Packaging: Used as a waterproof coating for corrugated boxes and food-grade wrapping to prevent moisture penetration.
Rubber & Plastic Processing: Acts as an external lubricant and ozone-protecting wax in tire manufacturing and PVC extrusion.
Wood Treatment: Applied as a sealant for medium-density fiberboard (MDF) and particleboard to control water absorption.
Textile & Leather: Utilized in finishing processes to provide gloss, smoothness, and improved handle to fabrics and leather goods.

For phase-change projects or a defined C18 hydrocarbon requirement, n-Octadecane is a separate linear alkane material.

Storage & Safety

Storage: Store in a cool, dry, well-ventilated area away from heat sources, open flames, and oxidizing agents. Keep the temperature below 45°C to prevent melting or deformation of the slabs/pellets. Avoid direct sunlight.
Safety (PPE): Wear heat-resistant gloves and safety goggles when handling the material in its molten state to prevent thermal burns. Use standard dust masks if handling powdered or flaked forms to avoid respiratory irritation.

Quality Assurance

Our Paraffin Wax production involves advanced solvent de-oiling and hydro-refining processes to achieve ultra-low oil content and high oxidation stability. Each batch undergoes rigorous testing for penetration, melting point, and color stability. We ensure that our fully refined grades meet the strictest industrial standards for purity, providing a consistent raw material for high-precision manufacturing and sensitive packaging applications.+1
