Spanjaard rubber Grease is a rubber-compatible lubricating grease developed to provide stable lubrication at interfaces where rubber components are in continuous contact with metal or other elastomers. During use, it delivers smooth mechanical movement while maintaining the original physical integrity of rubber parts. The grease applies evenly, remains in place over time, and provides consistent tactile response without causing swelling, softening, or surface degradation, supporting predictable performance during routine operation and maintenance.

• Friction Stability - Under moderate mechanical load conditions typical for rubber-to-metal interfaces, the Spanjaard Rubber Grease demonstrates a stable coefficient of friction in the range of 0.08–0.12 during repeated motion testing. Extended cycle evaluation exceeding 100,000 reciprocating movements shows no abnormal torque increase or stick-slip behavior. This controlled friction range supports predictable motion and reduced surface wear over prolonged service intervals.

  
  

• Rubber Compatibility - Compatibility testing with common elastomers such as natural rubber, NBR, and EPDM indicates volume change controlled within ±3 percent after prolonged immersion exposure. Hardness variation remains within ±5 Shore A, confirming that the formulation does not induce swelling, hardening, or cracking. These limits meet accepted elastomer lubrication compatibility thresholds for long-term contact.

  
  

• Chemical Stability - Oxidative stability assessment under accelerated aging conditions shows minimal base oil degradation, with viscosity change maintained within ±10 percent after extended exposure. No measurable acidic by-products or polymer breakdown residues are detected. This chemical stability ensures consistent lubrication behavior without initiating chemical reactions with rubber compounds.

  
  

• Consistency Control - The grease is manufactured with controlled semi-solid consistency corresponding to NLGI Grade 2, ensuring stable retention at the lubrication interface. Rheological testing confirms consistent yield stress and flow behavior across typical operating temperature ranges, preventing excessive migration while maintaining continuous lubricant film coverage on seals and bushings.

  
  

• Thermal Operating Range - The formulation remains functional across a typical service temperature range of approximately −20 °C to +120 °C. Within this range, penetration and consistency remain within specified tolerances, preventing hardening at low temperature or oil separation at elevated temperature. This thermal stability supports reliable lubrication performance under variable operating conditions.

• Cold Starting Systems - Spanjaard Rubber Grease is used in cold-start mechanisms where rubber seals and moving interfaces must remain functional at low temperatures. The grease maintains lubricity without stiffening, supporting smooth actuation during initial startup cycles. This reduces mechanical resistance and start-up wear in low-temperature conditions.

  
  

• Emergency Activation Systems - The grease is applied in emergency mechanisms that rely on rubber-based seals or flexible components. Stable lubrication supports immediate mechanical response while preserving seal integrity. This ensures reliable operation during sudden activation or safety-critical engagement.

  
  

• Industrial Engine Assemblies - Spanjaard Rubber Grease is used on rubber components within industrial engines, including gaskets and flexible interfaces. The formulation supports long-term lubrication without altering rubber properties, helping maintain sealing effectiveness and alignment. This contributes to consistent performance during extended operating cycles.
