Continuous Improvement (Kaizen): Lean Manufacturing in a Rubber Factory

Problem Statement

High-pressure hydraulic seals experience compression set failure after 10,000 cycles at 150°C and 20 MPa. This leads to fluid leakage and system downtime.

Material Science Analysis

Standard NBR fails due to its low thermal stability and poor resistance to hydraulic fluids. FKM (Fluorocarbon Rubber) succeeds because its fluorine-carbon backbone provides superior thermal stability and chemical resistance. Fluorine content above 65% ensures minimal compression set degradation under high-pressure cycles.

Technical Specs

• Material: FKM (Grade: RubberQ-FKM-200)
• Shore A Hardness: 75 ± 5
• Tensile Strength: 15 MPa
• Elongation at Break: 200%
• Temperature Range: -20°C to 200°C
• Compression Set (22 hrs @ 175°C): ≤ 15%
