Can EPDM rubber strip maintain stable performance in environments such as engine compartments where it comes into contact with chemical liquids such as engine oil and gasoline?

In the automobile manufacturing industry, can EPDM rubber strip maintain stable performance in environments such as engine compartments where it comes into contact with chemical liquids such as engine oil and gasoline, ensuring the long-term safe operation of the car?

EPDM rubber is widely used in the automobile manufacturing industry. Its properties include excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and room temperature fluidity. wait. At the same time, due to its low polarity and low unsaturation, EPDM also has good tolerance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and lipids, etc. .

However, although EPDM rubber exhibits good chemical resistance in most cases, it has poor stability in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and performs poorly under the long-term action of concentrated acid. will also decrease. The engine compartment is a complex environment, which contains chemical liquids such as engine oil and gasoline. These liquids may belong to the category of solvents with poor stability of EPDM rubber.

Therefore, although EPDM rubber has many excellent properties, its stability may be affected to a certain extent in environments such as engine compartments where it is exposed to chemical liquids such as engine oil and gasoline. In order to ensure the long-term safe operation of automobiles, automobile manufacturers need to fully consider the compatibility of EPDM rubber with these chemical liquids and may need to conduct specific testing and verification.

In addition, the automobile manufacturing industry usually considers a variety of factors when selecting materials, including material performance, cost, processability, etc. Therefore, even though EPDM rubber may have slightly deficient properties in some aspects, it may still be used in certain applications due to its other advantages.

Whether EPDM rubber strip can maintain stable performance in environments such as automobile engine compartments where it comes into contact with chemical liquids such as engine oil and gasoline needs to be evaluated based on the application environment and conditions. In order to ensure the long-term safe operation of automobiles, it is recommended that automobile manufacturers fully test and verify the performance of selected materials in actual applications, and take appropriate protective measures when necessary.
