Are you dissatisfied with the bad performance of the hoses on your old machine? Unsure which type of hose to choose for your product? After reading this article, you will understand the differences between rubber and silicone hoses and select a more suitable hose for your machine.
Raw Materials for Silicone Hoses and Rubber Hoses
As its name suggests, a rubber hose is usually made from natural and synthetic rubber. Through vulcanization, rubber becomes elastic and gains a certain degree of strength. It is widely used in many areas of industry and daily life, and rubber hoses are one example.
The initial raw material for silicone hoses is quartz sand. Through a series of processing steps, it is transformed into silicone rubber, the main material of the hoses. It is used in various fields, including medicine, food, and products designed for babies.
Costs and Service Life
Rubber Hoses: Cheaper Prices
Due to the complexity of raw material sourcing and manufacturing processes, rubber hoses are significantly cheaper than silicone hoses. They are ideal for manufacturers who need to purchase hoses in bulk and want to minimize short-term costs.
Silicone Hoses: A Cost-effective Choice for Long-term Use
However, this is only a comparison of unit price. If you plan to use the hose for a long period of time, silicone hoses are a better choice. Silicone hoses are much more durable than rubber hoses. Rubber hoses need to be replaced after only 3 to 7 years, but high-quality silicone hoses can even last 20 years.
If you need a hose for short-term use, rubber hoses have a lower price, but silicone hoses can help you save more money in the long run. Damage to hoses can result in both time and financial losses. It means your factory will need to halt production for a period of time, and you’ll need to hire specialists to replace them.
How Do They Perform at Different Temperatures
Silicone Hoses: Can Operate in Extreme Temperatures
Silicone hoses have a wider temperature adaptation range. It can work normally from -40°C to 220°C. Silicone hoses specifically manufactured for high-temperature environments can withstand higher temperatures.
One of the major advantages of silicone hoses is that they can function normally within their labeled temperature range without the risk of adhering to surrounding parts, which would make disassembly and replacement difficult. Even in extremely cold temperatures, silicone hoses will not harden or undergo any other changes in their physical properties.
Due to the excellent temperature adaptability, silicone hoses can be used in laboratories or food processing industries that involve steps such as boiling and distillation. They are also reliable automotive components that can play a part in your car’s radiator, coolant transportation system, and other systems.
Rubber Hoses: The Choice for Normal Temperature Environments
The optimal temperature range for rubber hoses is -40°C to 93°C. Although EPDM rubber hoses can tolerate higher temperatures, it is still far below the maximum temperature that the silicone hose can withstand.
Working in an environment with heat can accelerate the aging and even the expansion of rubber hoses. This will significantly shorten the lifespan of the rubber hose and create safety hazards during machine operation. In extremely cold environments, rubber hoses lose their original properties, becoming harder and more prone to cracking.
Therefore, rubber is more suitable for mechanical systems or equipment operating at normal temperatures, such as cooling systems, gas transmission systems, agricultural irrigation, and other related areas.
Performance in Resisting Ultraviolet Radiation
If your machine will be used outdoors, you must be concerned about the UV resistance. Generally speaking, silicone hoses have better UV resistance. Its stable chemical structure, combined with the added UV absorbers, maximizes its lifespan in outdoor use.
Sunlight can further shorten the lifespan of rubber hoses, causing them to gradually degrade, so rubber hoses are not suitable for outdoor use. So if you are choosing hoses for your boat or weather-related equipment, silicone hoses would be a better choice.
The Ability of Tolerance to Ozone
In certain electrical equipment and outdoor facilities, high ozone concentrations have become a factor in testing the performance of hoses. In this respect, the stable chemical structure of silicone hoses makes them less susceptible to the effects of ultraviolet radiation. Specialized silicone hoses are also surface-treated, allowing them to better withstand ozone attack.
The Safety of Silicone and Rubber Hose
Silicone Hoses: Providing a Safer Guarantee for Food and Medical Applications
As a food-grade and even medical-grade material, silicone offers ample safety indemnification. Food-grade and medical-grade silicone has no odor and does not release substances harmful to human health when transporting liquids or gases. They are very safe and remain stable even under high-temperature steam and heating.
They are easy to clean, and liquids do not easily accumulate inside. Even with the use of strong cleaning agents, the silicone hose will not be damaged. As long as they are used correctly and maintained regularly, the safety of silicone hoses can be guaranteed even with long-term use.
When choosing silicone hoses for your food processing or medical equipment, please ensure that the manufacturer’s silicone raw materials meet FDA or USP standards to guarantee their quality.
Rubber Hoses: Designed for Industrial Use
Rubber often has a very distinct odor. That’s why it is generally used in industrial production. Although some factories use rubber hoses, there is no guarantee that the additives or odors in the rubber will not migrate into the liquids being transported. The odor of rubber may also introduce unknown allergens into the product.
Furthermore, rubber hoses are not as smooth and dense as silicone hoses, making them prone to retaining residual liquids and harboring microorganisms, so thorough cleaning is a challenge.
If you are a drinks manufacturer or a manufacturer of drink production equipment, you certainly don’t want to receive complaints or have your sales affected due to off-flavors in your drinks, do you? For machines in the food and medical fields, silicone hoses are obviously a wise choice.
Applicable Areas
Silicone hoses and rubber hoses can transport very different types of substances
Silicone Hoses: A Reliable Transporter Resistant to Corrosion
Silicone hoses have excellent chemical stability. They have excellent corrosion resistance and perform well even when used to transport most acids. However, silicone hoses are not recommended for transporting solvents, oils, or fuels such as petroleum, as they will swell when immersed in these substances.
Therefore, while you can choose more reliable silicone hoses for transporting most chemicals, do not use them in fuel delivery systems. If you need to use silicone hoses in a machine used for manufacturing chemicals, you can also choose specialized silicone hoses that offer superior performance in certain aspects.
Rubber Hoses: Experts in the Field of Fuel Transportation
Regarding the industrial demand for rubber hoses, there are many types of hoses available for some chemical or fuel transportation, such as NBR and FKM rubber hoses. Rubber hoses offer big advantages in the transportation of gasoline or diesel. If you are choosing hoses for your fuel delivery system, rubber hoses would be more suitable.
Physical Properties of Silicone and Rubber
Silicone Hoses: More Flexible and Maintains its Shape Even after Bending
Silicone hoses are known for their softness and strong flexibility. They can maintain good flexibility even at low temperatures. It is not prone to cracking, can withstand frequent movement, and is not afraid of being bent. And because of its smooth inner surface, it creates very little resistance and hardly impedes the flow of liquids or gases. They can also reduce vibrations and noise generated during the manufacturing process.
However, its pressure resistance is not particularly good. To withstand high-pressure environments, it often requires extra reinforcement and maintenance. It is also easily damaged under prolonged friction and impact. Frequent stretching can also cause it to lose its original elasticity.
Due to these physical properties, silicone hose is more suitable for low-temperature environments or environments where high flexibility is required. It can also be used in low-voltage and medium-voltage transmission systems.
Rubber Hoses: More Wear-resistant, More Pressure-resistant, and Possess a Certain Degree of Strength
You’ve certainly seen car tires rolling on the ground. Rubber is used to make tires because it has excellent wear resistance and is not easily damaged by external forces. In addition, rubber hoses can withstand high pressure, allowing them to maintain good strength when operating in high-pressure systems.
While they provide some support, their flexibility is not as good as that of silicone hoses, and they will crack if bent excessively. In addition, rubber hoses don’t reduce noise generation and may make the production workshop noisy.
For rubber hoses, systems that require resistance to high pressure, or those demanding abrasion resistance and higher strength, are where they truly shine.
Style and Color
Silicone hoses offer a much wider variety of styles and colors compared to rubber hoses.
Rubber Hoses: A Standard and Practical Choice
As industrial components, rubber hoses pay more attention to practicality, so they usually provide a limited number of colors, such as black, blue, and red, and offer fewer style choices. If you want to customize rubber hoses, it usually means causing high costs associated with custom molds or formulations.
Silicone Hose: A Wider Variety of Styles and Colors to Choose from
Silicone hoses come in a greater range of colors and surface textures, and their colors remain stable for many years. Clear or translucent silicone hoses allow for easy observation of internal processes. Some silicone hose manufacturers also offer customization options, and the customization costs are relatively low, allowing you to provide more personalized styles and appearances for your cars.
