Silicone hose and rubber hose are both for a variety of apps. But there are several differences between them. Next, let me show you silicone hoses vs rubber.
Silicone Hoses VS Rubber
1. Material differences
Silicone hoses are mainly made of synthetic polymer materials with siloxane as the main component, while rubber hoses are mainly made of natural rubber or synthetic rubber. Silicone has excellent high temperature resistance, low temperature resistance, and aging resistance, and is non-toxic, tasteless, and odorless, meeting food safety requirements.
In contrast, rubber hoses have better wear resistance and are suitable for occasions with frequent friction, but their temperature resistance is slightly inferior to that of silicone hoses.
2. Temp range
Silicone hose has a much wider temp range than rubber hose. Thus it’s more suitable for high temp use. Silicone hose can work at -60℃ to 200℃, while rubber hose can just work at -40℃ to 120℃.
3. Flexibility
Silicone hose is more flexible than rubber hose. So it’s more easier to install and route in tight spaces. Rubber hose can become stiff and brittle over time, especially in low temps.
4. Durability
Silicone hose is more durable than rubber hose. Because it resists crack, tear, UV and ozone. But rubber hose will crack over time, especially if it exposes to heat and sunlight.
5. Chemical resistance
Silicone hose has better chemical and oil resistance than rubber hose. Rubber hose can degrade over time when exposed to oil and gasoline. Then it will lead to leaks and failure.
6. Application scenarios
Depending on different application requirements, silicone hoses and rubber hoses each have their own advantages:
- Silicone hoses: Suitable for high-temperature working environments, chemical industry, food processing, medical equipment and other occasions that require high performance and high durability.
- Rubber hoses: Suitable for occasions with high mechanical pressure and wear resistance, such as the automotive industry, industrial transportation, etc.
7. Cost
Silicone hose is more expensive than rubber hose, because it’s more durable and high quality. Besides, the longer lifespan of silicone hose makes them a more cost-effective choice over time.
Overall, silicone hose is more durable, flexible than rubber hoses. While it may be more expensive. The longer lifespan and ability to bear high temp and chemical make them a popular choice for many apps.
