Understanding Silicone vs Elastomers
Comprehensive performance matrix comparing silicone to EPDM, NBR, FKM, and other elastomers. Cover property ranges and applications. This comprehensive guide covers everything you need to know about silicone vs elastomer. Whether you’re a buyer, product designer, or business owner, understanding these details will help you make informed decisions and select the right products for your specific needs.
Key Considerations
When evaluating silicone vs elastomer for your application, consider these critical factors:
- Application Requirements — What specific use case does your product serve? This determines material grade, hardness, and certification needs.
- Certification Requirements — Different markets and applications require different certifications (FDA, CE, ISO 10993). Verify requirements before sourcing.
- Cost vs Performance — Balance initial cost against lifespan, maintenance, and replacement frequency. Higher-quality silicone vs elastomer often provides better total cost of ownership.
- Supplier Capability — Verify factory certifications, quality systems, and production capacity match your requirements.
Industry Applications
silicone vs elastomer is used across diverse industries including:
- Food service and hospitality

Frequently Asked Questions
How does silicone compare to EPDM?
Silicone: wider temperature range (-60 to +230°C vs -50 to +150°C), food/medical grades available, better ozone resistance, higher cost. EPDM: excellent weathering, good steam resistance, lower cost, no food/medical grades. Choose based on application.
How does silicone compare to FKM (Viton)?
Silicone: lower cost, better low-temperature flexibility, food/medical grades. FKM: superior chemical resistance (fuels, solvents), higher temperature (200-250°C), no food contact, expensive. Use FKM for aggressive chemicals; silicone for food/medical.
How do I select between elastomers?
Consider: temperature range, chemical exposure, mechanical requirements, certifications needed, cost. Create application profile and rank requirements. Consult material selection guides and supplier data. Test prototypes under actual conditions. No universal best material.
