High-Tonnage Vulcanization: Managing Large-Scale Industrial Rubber Components
Problem Statement
Large-scale industrial rubber components, such as conveyor belts and hydraulic seals, face premature failure under high-tonnage vulcanization. Common issues include chemical degradation at temperatures exceeding 200°C and compression set failure during high-pressure cycles.
Material Science Analysis
Standard EPDM polymers fail under extreme heat due to their low fluorine content. FKM (Fluorocarbon Rubber) excels in high-temperature environments due to its fluorine-carbon backbone, which provides superior thermal stability and chemical resistance. HNBR (Hydrogenated Nitrile Rubber) offers enhanced tensile strength and aging resistance, making it suitable for dynamic applications.
Technical Specs
- Material: FKM
- Shore A Hardness: 75 ± 5
- Tensile Strength: 20 MPa
- Elongation at Break: 250%
- Temperature Range: -20°C to 250°C
Technical Comparison
| Material | Shore A Hardness | Tensile Strength (MPa) | Elongation at Break (%) | Temperature Range (°C) |
|---|---|---|---|---|
| FKM | 75 ± 5 | 20 | 250 | -20 to 250 |
| EPDM | 70 ± 5 | 15 | 300 | -40 to 150 |
| HNBR | 80 ± 5 | 25 | 200 | -30 to 180 |
