Description

Lubricating Oils, Used, Distd., Hydrotreated, C30-50 Fraction is a high-quality, re-refined base oil derived from post-consumer lubricants through advanced distillation and hydrotreating processes. This product matters as a sustainable and cost-effective alternative to virgin base oils, offering reliable performance while supporting circular economy initiatives in the lubricants industry. It is essential for industrial lubricant blenders, formulators, and manufacturers seeking consistent, high-performance base stocks for a variety of demanding applications.

Application

• Industrial Lubricant Formulation: As a primary base stock for manufacturing hydraulic fluids, gear oils, compressor oils, and other industrial lubricants.
• Metalworking Fluids: Used in the production of soluble oils, semi-synthetic, and synthetic metalworking fluids for cutting, grinding, and stamping operations.
• Process Oils: Serves as a base or component in process oils for the rubber, plastic, and textile industries.
• Grease Manufacturing: Acts as a key fluid component in the production of calcium, lithium, and other complex soap-based greases.
• Transformer and Heat Transfer Oils: Suitable for formulating specialized dielectric and thermal fluid products after further treatment and additive incorporation.
• Marine and Railroad Lubricants: Used in blending cylinder oils and other heavy-duty lubricants for marine engines and rail applications.
