Slack wax is a by-product of lubricating oil refining, derived during the vacuum distillation process where paraffin and microcrystalline waxes are separated from base oils. Composed primarily of oil and wax, it serves as a raw material for the production of paraffin wax and is valued for its versatility across industries.
Appearance & Classification
Typically yellow to brown in color, slack wax is categorized by its melting point:
• Light Grade: 50–52°C
• Heavy Grade: 53–55°C
It contains between 5% and 30% oil, with higher oil content generally resulting in a lower market price.
Applications
• Candle manufacturing
• Wax emulsions
• Textile finishing
• Insulation and glass wool production
• Paraffin wax production
Slack wax with 10%–30% oil content is particularly suitable for use in colder regions such as Turkey, Russia, and Ukraine.
Key Advantages
• High melting point
• Light color
• Cost-effective precursor to paraffin wax
Packaging Options
• Reconditioned drums
• Oversized bags
• Flexitanks
Storage Guidelines
Store indoors whenever possible. If outdoor storage is necessary, keep covered and shielded from direct sunlight, rain, and snow to preserve product integrity.
Safety & Handling
Stable under normal conditions. Not expected to cause irritation to skin or eyes with standard handling.
