Silicone O-Rings vs. Rubber O-Rings: Key Differences


 

Discover the disparities between silicone and rubber O-rings to select the optimal sealing solution.

 

Delve into their properties, applications, and advantages.

 

Material Composition:

 

Silicone O-Rings: Crafted from silicone polymer, providing flexibility and temperature resistance (-60°C to 230°C).

 

Rubber O-Rings: Comprised of diverse rubber compounds like NBR, EPDM, neoprene, or FKM, each with distinct properties.

Company name: Zhongshan Melon Rubber & Plastic Products Co., Ltd.

 

Performance Characteristics:

 

Silicone O-Rings vs. Rubber O-Rings

 

Silicone O-Rings are known for their flexibility, low compression set, and excellent electrical insulation. They are perfect for applications in food, pharmaceuticals, electronics, and extreme temperature environments.

 

Rubber O-Rings, on the other hand, are versatile, resistant to abrasion, tearing, and mechanical stress. They are widely utilized in hydraulic systems, automotive engines, and industrial machinery.

 

When choosing between the two, opt for silicone O-Rings for temperature extremes and specialized applications, while rubber O-Rings offer versatility and durability in demanding conditions.
