Advanced Materials for Extreme Conditions
Material Science: The Foundation of Sealing Success
Modern industrial processing regularly pushes temperature, pressure, and chemical aggressiveness to extreme levels. Surviving these conditions requires selecting advanced materials engineered for extreme durability.
1. Seal Face Materials
| Material | Thermal Conductivity | Best Applied For |
|---|---|---|
| Silicon Carbide (SiC) | Extremely High | Corrosive fluids, fast rotation, and general industrial water. |
| Tungsten Carbide (TC) | High | Slurries, high pressures, and heavy vibration. Resistant to fracture. |
| Resin Carbon | Medium | Excellent dry-running/self-lubrication properties in clean fluids. |
2. Elastomers and O-Rings
- Viton (FKM): Outstanding chemical resistance in oils, fuels, and acids up to 180°C.
- EPDM: The premier choice for hot water, steam, and water-glycol mixtures up to 140°C.
- PTFE (Teflon): Fully inert to virtually all acids and alkalis, making it indispensable in heavy chemical applications.
