Rubber O-ring seals are commonly used in various industries for their excellent sealing properties. These seals are made from different types of rubber materials, each with its own chemical resistance properties. Here are some common rubber materials used for O-ring sealing and their chemical compatibility:
1. Nitrile rubber (NBR): Nitrile rubber is a widely used material for O-ring sealing due to its excellent oil and fuel resistance. It is resistant to many aliphatic hydrocarbons, petroleum oils, mineral oils, vegetable oils, and greases. However, it is not recommended for use with polar solvents, ketones, esters, and aromatic hydrocarbons.
2. Fluorocarbon rubber (FKM): Fluorocarbon rubber, also known as Viton, is highly resistant to a wide range of chemicals, including acids, bases, aliphatic and aromatic hydrocarbons, and many organic solvents. It is commonly used in applications where high temperature and chemical resistance are required.
3. Ethylene Propylene Diene Monomer (EPDM)…
