Semi Distilled Base Oil

About Semi Distilled Base Oil

Semi Distilled Base Oil is a partially refined petroleum product obtained through controlled distillation and mild refining processes. It lies between crude oil and fully refined base oils in terms of purity, viscosity, and performance. This type of oil retains some natural hydrocarbons while removing major impurities, making it suitable for various industrial and low-to-medium performance lubrication applications.

Key Specifications

Typical properties (may vary depending on source and processing method):

• Appearance: Light yellow to brown liquid
• Viscosity (at 40C): 30 150 cSt
• Density (at 15C): 0.85 0.92 g/cm
• Flash Point: 180 260C
• Pour Point: -3C to 15C
• Sulfur Content: Moderate (higher than fully refined oils)
• Aromatic Content: Medium
• Volatility: Low to moderate
• Solubility: Insoluble in water, soluble in hydrocarbons

Applications

Semi distilled base oil is widely used in industries where ultra-high purity is not required:

1. Lubricants & Greases

• Industrial lubricants
• Low-grade engine oils
• Machinery lubrication

2. Rubber & Tire Industry

• Processing oil in rubber compounding
• Improves flexibility and workability

3. Textile Industry

• Spinning and weaving lubricants
• Anti-static oil formulations

4. Construction & Road Work
