When selecting rubber materials for industrial use, understanding key differences is critical.
Here’s a focused comparison of Silicone Rubber (SIL) with other common elastomers:
Silicone Rubber (SIL) Key Features:
- Exceptional heat resistance (performs well in extreme temperatures)
- Superior weather/ozone resistance (ideal for outdoor applications)
- Excellent electrical insulation (widely used in electronics)
- Poor mechanical strength (not suitable for high-stress environments)
- Not oil-resistant (avoid fuel/oil exposure)
How It Stacks Up Against Others:
– vs. Natural Rubber (NR): SIL wins in aging/weather resistance but lacks NR’s elasticity.
– vs. EPDM: Both resist ozone/weather, but EPDM handles brake systems better (oil-free).
– vs. Nitrile (NBR): NBR excels in oil resistance but falls short in extreme heat.
– vs. Fluorocarbon (FVMQ/VITON): FVMQ outperforms SIL in oil/fuel resistance but at a higher cost.
If you’re designing components that demand precision, durability, and biocompatibility, here’s why Silicone Rubber stands out:
🔹 Silicone Rubber (VMQ)
• Excellent flexibility and high temperature resistance (-60°C to 250°C)
• Outstanding weather, ozone, and aging resistance
• Perfect for medical and food-grade applications
• Not ideal for oil/fuel exposure
🔹 Fluorosilicone Rubber (FVMQ)
• All the benefits of silicone, plusfuel/oil resistance
• Ideal for harsh environments like aerospace and automotive
🔹 Fluoro Rubber (FKM/VITON)
• Superior chemical, fuel, and heat resistance
• Trusted in demanding industrial applications
Best Use Cases for Silicone Rubber:
– Seals/gaskets in high-temperature environments
– Medical/electronics (biocompatible, insulating)
– Outdoor industrial components (UV/ozone resistant)
