ALKYL ARYL SULFONATES Resistant O-Rings and Seals

Alkyl Aryl Sulfonates, also known as alkylbenzene sulfonates, are a class of organic compounds commonly used in a variety of industries including household cleaning products, oilfield chemicals, and paper and pulp production. These compounds are used as surfactants and emulsifiers, helping to increase the effectiveness of cleaning agents and dispersing oils and hydrophobic materials.

Common types of failures when rubber is exposed to alkyl aryl sulfonates include swelling, cracking, and loss of elasticity. Alkyl aryl sulfonates can penetrate the rubber surface and cause degradation of the polymer structure, making it more brittle and prone to cracking. Additionally, the presence of these compounds can cause swelling of the rubber material, making it less effective in its original use. As such, it is important to use rubber materials specifically designed to resist alkyl aryl sulfonates when dealing with these compounds.
