Red Rubber Grease vs Silicone Grease.
Red Rubber Grease vs Silicone Grease
When it comes to maintaining and lubricating rubber and plastic components, choosing the right grease can make a significant difference in performance and longevity. This article delves into the key differences between two popular greases: red rubber grease and silicone grease. We’ll explore their properties, applications, and benefits to help you make an informed decision for your specific needs.
Understanding Red Rubber Grease
Spanjaard Rubber Grease is an inorganically thickened, vegetable-oil based grease fortified with extreme pressure and anti-corrosion additives. This makes it highly compatible with natural and synthetic rubbers, preventing issues such as swelling or hardening.

Understanding Red Rubber Grease
Spanjaard Rubber Grease is an inorganically thickened, vegetable-oil based grease fortified with extreme pressure and anti-corrosion additives. This makes it highly compatible with natural and synthetic rubbers, preventing issues such as swelling or hardening.
Key Properties of Red Rubber Grease:
- Consistency (NLGI Grade): 2
- Worked Penetration, 25ºC, 1/10mm: 265-295
- Colour: Red, translucent
- Thickener: Inorganic
- Drop Point, ºC: None
- Dynamic Rust Test: <1
- Copper Corrosion - 24hr/100ºC: Pass
- Useful Temperature Range ºC: -20 to 180
- Flash Point, ºC: >250
Applications:
- Hydraulic Brake, Clutch, and Suspension Rubbers: Prevents swelling or hardening.
- Rubber Components: Ideal when mineral oil-based lubricants are incompatible.
- Plastic and Rubber Components: Lubricates o-rings, valves, diaphragms, cups, and seals.
- Swimming Pool Seals: Ensures durability and resistance to water.
- Train Air Brake Components: Lubricates rubber cylinder rolls.
- General Rubber Lubrication: Suitable for a wide range of rubber applications.
Benefits:
- High dropping point.
- Excellent water resistance.
- Compatibility with a wide range of rubber and plastic materials.
Understanding Silicone Grease
Spanjaard Silicone Paste is a stable, non-melting paste composed of silicone oil thickened with an inorganic gelling agent. It is known for its exceptional resistance to water, excellent insulating properties, and versatility as a release agent.
Key Properties of Silicone Grease:
- Consistency (NLGI Grade): 3
- Worked Penetration, 25ºC, 1/10mm: 220
- Colour: White translucent
- Thickener: Silica
- Drop Point, ºC: None
- Evaporation Loss 30hrs @ 175ºC, %: 1.0
- Dynamic Rust Test: <1
- Copper Corrosion - 24hr/100ºC: Pass
- Oil Bleed 30h @ 175ºC, %: 0.2
- Water Wash Out @ 93ºC, %: 1.0
- Timken OK Load, kg: 1
- Oxidation Resistance, D942, %: 1.0
- Dielectric Strength, kV/mm: 15
- Useful Temperature Range ºC: -40 to 200
- Silicone Oil Properties (Oil Viscosity cSt, 40ºC): 750
- Flash Point, ºC: >250
Applications:
- Lubricant for Low Speed and Light Load Bearings: Ideal for parts and mechanisms.
- Rubber and Plastic Lubrication: Refrigerator and car door seals, swimming pool seals, plastic gears, and more.
- Electrical Insulation: Seals and protects electrical equipment, preventing moisture ingress and corrosion.
- Release Agent: Useful in the rubber and plastics industries to prevent binding and ensure smooth release of components.
- Corrosion Protection: Protects chrome plating, seals screw threads, and automobile battery terminals.
Benefits:
- Excellent water and corrosion resistance.
- Non-conductive, preventing electrical leakage and short-circuiting.
- Effective in a wide range of temperatures and conditions.
Comparing Red Rubber Grease and Silicone Grease
Temperature Resistance:
Temperature Resistance:
- Red Rubber Grease: Useful from -20ºC to 180ºC.
- Silicone Grease: Wider range from -40ºC to 200ºC.
Compatibility:
- Red Rubber Grease: Best for rubber components that need to avoid mineral oil-based lubricants.
- Silicone Grease: Suitable for various materials including plastics and metals, but not for High Impact Polystyrene (HIPS).
Special Properties:
- Red Rubber Grease: Fortified with extreme pressure and anti-corrosion additives.
- Silicone Grease: Provides excellent insulating properties and serves as a release agent.
Applications:
- Red Rubber Grease: Focused on rubber components in hydraulic systems, plastic gears, and train air brake applications.
- Silicone Grease: Versatile use in electrical insulation, light load lubrication, and as a release agent in manufacturing.
Conclusion
Choosing between red rubber grease and silicone grease depends on your specific application needs. Spanjaard Rubber Grease is ideal for applications requiring high compatibility with rubber and resistance to mineral oil-based lubricants. In contrast, Spanjaard Silicone Paste offers superior temperature resistance, excellent electrical insulation, and multi-purpose utility as a lubricant and release agent. Evaluate your requirements to determine which grease best suits your needs, ensuring optimal performance and longevity of your components.
