There are ten different types of silicone rubber hoses, the English abbreviations are: NR, IR, BR, SBR, NBR, IIR, EPDM, CR, SR, FKM. So how to identify these ten types of silicone rubber tubes? Silicone rubber hose manufacturers tell you.
Nine ways to teach you to identify the type of silicone hoses
- Observe the color
The color of silicone rubber hose is usually related to its type. For example, red silicone rubber hose is often used for high temperature applications, while blue silicone rubber hose is usually used for low temperature applications. Yellow silicone rubber hoses are commonly used in the food and pharmaceutical industries. - Check hardness
The hardness of silicone rubber hose is usually related to its type. Hardness can be measured by using a durometer. For example, a silicone rubber hose with a durometer of 60 Shore A is typically used for general industrial applications, while a silicone rubber hose with a durometer of 70 Shore A is typically used for high temperature applications. - Test heat resistance
Silicone rubber hoses are generally very heat resistant. However, the heat resistance of different types of silicone rubber hoses is also different. You can identify the type of silicone rubber hose by exposing it to high temperatures and testing its heat resistance. For example, silicone rubber hoses with a heat resistance temperature around 150°C are usually used for low temperature applications, while those with a heat resistance temperature above 200°C are usually used for high temperature applications. - Confirm the silicone rubber material
The material of the silicone rubber hose is also an important indicator of its type. Silicone rubber hoses are usually divided into two types: organic silicone rubber and inorganic silicone rubber. Silicone rubbers are typically used in general industrial applications, while inorganic silicone rubbers are typically used in high temperature and corrosion resistant applications. - Check the logo
Silicone rubber hoses are usually marked with their type and specification on their surface. These identifications may include the manufacturer’s name, model number, date of manufacture, hardness, etc. Checking the markings can help you determine the exact size and purpose of the hose. - Check chemical resistance
Silicone rubber hoses are often used to transport chemicals or high temperature liquids. Therefore, its chemical resistance is also an important indicator to identify its type. When purchasing silicone rubber hose, you should verify that it is resistant to substances that will chemically react with the liquid or gas it comes in contact with. - Test pressure resistance
The pressure resistance of silicone rubber hose is also a key indicator of its type. You can identify the type by exposing the hose to high pressure and testing its pressure resistance. The pressure resistance of silicone rubber hose is related to its material, structure and manufacturing process. - Check temperature range
The operating temperature range of silicone rubber hose is also an important indicator to identify its type. Different silicone rubber hoses can withstand different temperature ranges, generally speaking, industrial grade silicone rubber hoses can withstand temperatures up to 200°C. When purchasing silicone rubber hose, you should confirm whether its temperature range meets your needs. - Check the surface
The surface quality of silicone rubber hose can also help you identify its type. The surface of a good silicone rubber hose should be flat and smooth, without obvious unevenness or bubbles, which will not affect its performance and service life. When purchasing silicone rubber hose, you should check whether its surface meets the requirements.
In general, the type and performance of silicone rubber hose is very important. Identifying the type of silicone rubber hose requires a combination of factors, including material, use, specification, hardness, temperature range, and more. When purchasing silicone rubber hose, you need to fully consider these factors and choose the appropriate model and specification that meets your needs.
