One of the material options for hydraulic seals: rubber seals

In the selection of seals for hydraulic systems, rubber materials are attracting attention due to their diverse properties and wide range of applications. Rubber seals play a vital role in hydraulic systems due to their excellent elasticity and sealing properties. The following is a detailed analysis of the rubber seals:

Nitrile rubber (NBR)

Features

Oil resistance: Nitrile rubber has excellent oil resistance and is particularly suitable for contact with petroleum-based liquids, hydrocarbon compounds, and moderately polar chemical media.

Abrasion resistance: Its wear resistance is also good, and it is suitable for use in hydraulic systems that require wear resistance.

Data support

Oil Resistance Test: At room temperature, NBR has long-term stability against a wide range of oil media, and its oil resistance can be up to several years.

Abrasion Resistance Test: After wear test, NBR has a low wear rate and shows excellent wear resistance.

Application Scenarios:

It is suitable for general hydraulic systems, such as machine tools, injection molding machines, etc., especially in the case where oil and wear resistance are required.

Fluoroelastomer (FPM)

Features

High-temperature resistance: Viton has excellent high-temperature resistance and can maintain stable performance in high-temperature environments.

Chemical resistance: It has good resistance to acids, alkalis, solvents, etc., making it suitable for strong corrosive environments.

Data support

High Temperature Performance Test: FPM can maintain stable performance at high temperatures of 200°C, and in some cases can withstand temperatures up to 250°C.

Corrosion resistance test: In a variety of strong acids, strong alkalis, and organic solvents, FPM has excellent corrosion resistance.

Application scenarios

It is suitable for high-temperature and strongly corrosive hydraulic systems, such as petrochemical, metallurgical, and other fields.
