Grease

Description

Calcium-Based Grease
Calcium-based grease is a semi-solid lubricant formulated by dispersing a calcium soap thickener in mineral oil. This versatile grease provides excellent water resistance, corrosion protection, and adhesion properties, making it suitable for various industrial and automotive applications.

Key Characteristics of Calcium-Based Grease:

• Free Acid: 0.2% wt – Ensures minimal acidity, reducing corrosion risks.
• Penetration (unworked and worked): 1000 (ASTM D-1298) – Measures grease consistency and resistance to deformation.
• Dropping Point: 102°C – Indicates the temperature at which grease begins to liquefy.
• Flash Point: 174°C – Ensures thermal stability and safe operating conditions.
• NLGI Grade: 3 – Represents a thick consistency suitable for heavy-duty applications.

Applications of Calcium-Based Grease:

• Automotive Bearings and Chassis: Provides long-lasting lubrication and protects against wear.
• Agricultural Equipment: Ensures smooth operation in wet and dusty environments.
• Industrial Machinery: Protects metal surfaces from corrosion and reduces friction in gears and bearings.
• Marine Applications: Excellent water resistance makes it ideal for use in marine and offshore equipment.

Benefits of Calcium-Based Grease:

• Water Resistance: Superior protection in wet conditions, preventing rust and washout.
• Adhesion: Clings to metal surfaces, reducing the need for frequent reapplication.
• Anti-Corrosion Properties: Forms a protective barrier against moisture and contaminants.
• Simple Application: Available in new steel drums for easy handling and storage.

Lithium Grease (EP Grade)
Lithium grease is a multi-purpose lubricant formulated with lithium soap as a thickener. It offers excellent performance under extreme pressure (EP) conditions, providing superior load-carrying capacity, wear resistance, and high-temperature stability.

Test Parameters and Results:

• Soap Type: EP – Extreme pressure-resistant formulation.
• Dropping Point: Min 180°C (ASTM D-566) – Ensures stability at high temperatures.
• Worked Penetration @ 25°C:
  • NLGI 1: 310-340 mm/10
  • NLGI 2: 265-295 mm/10 (ASTM D-217)
• Mineral Oil Viscosity:
  • @ 40°C: Min 160 cSt (ASTM D-445)
  • @ 100°C: Min 15 cSt (ASTM D-445)
• Water Wash-out Resistance:
  • NLGI 1: Max 10%
  • NLGI 2: Max 5% (ASTM D-1264)
• Copper Strip Corrosion: 1b (ASTM D-4048) – Non-corrosive to copper components.
• Oil Separation (18 hours @ 40°C): Max 5% (ASTM D-1742) – Ensures minimal leakage.
• Operating Temperature Range: -20 to 120°C – Suitable for diverse environments.
• Color: Yellow

Applications of Lithium Grease:

• Automotive Components: Ideal for wheel bearings, chassis, and universal joints.
• Heavy Machinery: Reduces friction and wear in industrial gearboxes and bearings.
• Construction Equipment: Ensures lubrication under heavy loads and harsh conditions.
• Home and Workshop Use: Multi-purpose grease for tools, hinges, and small machinery.

Advantages of Lithium Grease:

• Versatility: Performs well across a broad range of temperatures and applications.
• Load Resistance: Withstands high pressures without breaking down.
• Anti-Wear Protection: Extends equipment lifespan by reducing metal-to-metal contact.
• Corrosion Resistance: Protects against rust and oxidation, even in humid environments.

Lithium grease is packaged in durable steel drums to maintain quality and simplify transport.
