Common Rubber Materials: Properties and Applications
Rubber is widely used in sealing, insulation, shock absorption, and various industrial applications. Choosing the right rubber material ensures durability, chemical resistance, and cost-effectiveness. In this guide, we compare NBR, EPDM, Silicone, Viton (FKM), and Natural Rubber (NR) to help engineers and buyers select the best compound for their needs.
🔍 Overview: Rubber Types at a Glance
| Material | Full Name | Temp. Range | Key Features | Common Uses |
|---|---|---|---|---|
| NBR | Nitrile Butadiene | -30℃ ~ +100℃ | Excellent oil resistance, cost-efficient | Oil seals, fuel systems |
| EPDM | Ethylene Propylene | -40℃ ~ +130℃ | UV & steam resistant, weatherproof | Water systems, solar seals |
| Silicone | Silicone Rubber | -40℃ ~ +200℃ | Food-safe, flexible, wide temp range | Food processing, medical, gaskets |
| Viton | Fluoroelastomer (FKM) | -20℃ ~ +200℃ | Chemical & heat resistance | Chemical plants, aerospace |
📌 Detailed Analysis of Rubber Materials
1. NBR (Nitrile Rubber) – Best for Oil Resistance
Pros: Oil resistance, abrasion resistance, widely used in industry
Cons: Not UV or ozone resistant
Applications: O-rings, hydraulic seals, fuel hoses
2. EPDM – Ideal for Outdoor and Water Use
Pros: Weather, UV, and steam resistance
Cons: Not oil-resistant
Applications: Drinking water gaskets, HVAC seals, solar panel systems
3. Silicone – Safe for Food & Medical Use
Pros: Excellent temp flexibility, FDA-compliant, non-toxic
Cons: Lower mechanical strength
Applications: Medical tubing, kitchenware, appliance gaskets
4. Viton (FKM) – Premium for Harsh Chemicals
Pros: Heat, fuel, and acid resistance
Cons: High cost, not food-safe
Applications: Aerospace, automotive engine seals, chemical valves
