When comparing FKM vs Silicone for your specific application needs, there are a few key factors to consider. Here is a step-by-step guide to help you understand the differences between these two materials:
1. Chemical Resistance:
- FKM (fluoroelastomer) offers superior chemical resistance compared to silicone. It can withstand a wider range of chemicals, including oils, fuels, and solvents. If your application involves exposure to harsh chemicals, FKM may be the better choice.
2. Temperature Resistance:
- Silicone has better resistance to high and low temperatures compared to FKM. It can withstand extreme temperatures ranging from -60°C to 230°C. If your application involves extreme temperature variations, silicone may be the more suitable option.
3. Compression Set:
- FKM has a lower compression set compared to silicone. This means that FKM can maintain its shape and seal integrity over time better than silicone. If your application requires a material with good compression set resistance, FKM may be the preferred choice.
4. Cost:
- Silicone is generally more cost-effective compared to FKM. If cost is a significant factor in your decision-making process, silicone may be the more economical option.
5. Application:
- Consider the specific requirements of your application when choosing between FKM and silicone. If your application involves exposure to chemicals, FKM may be the better choice. If temperature resistance is critical, silicone may be more suitable.
In conclusion, when comparing FKM vs Silicone, it is essential to consider factors such as chemical resistance, temperature resistance, compression set, cost, and specific application needs. By evaluating these factors carefully, you can determine which material is the best fit for your project.
