How Are The Acid And Alkali Resistance Properties Of Rubber Pads?

The acid and alkali resistance of rubber pads varies depending on the type of rubber.

 

Natural rubber pads have poor acid and alkali resistance. In acidic or alkaline environments, their chemical bonds are easily broken, leading to swelling, softening, and reduced strength, making them unsuitable for use in strong acid and alkali environments.

 

Nitrile rubber pads have some acid and alkali resistance. They have good tolerance to weak acids and bases and are widely used in common acid and alkali environments in chemical and mechanical industries. However, their performance gradually declines under high concentrations of strong acids and bases.

 

Ethylene propylene diene monomer (EPDM) rubber pads have good acid and alkali resistance. They have a stable chemical structure and maintain stable performance over a wide range of acid and alkali concentrations and temperatures, making them suitable for handling acidic substances such as sulfuric acid and hydrochloric acid, as well as alkaline substances such as sodium hydroxide.

 

Fluororubber pads have excellent acid and alkali resistance. They can withstand corrosion from high concentrations of strong acids and alkalis and maintain their physical and chemical properties even in harsh acid and alkali environments with high temperatures and strong corrosion. They are commonly used in aerospace, chemical, and other fields with extremely high requirements for acid and alkali resistance.
