BUTYL STEARATE Resistant O-Rings and Seals
Butyl stearate, also known as butyl ester of stearic acid, is a common industrial chemical used to make lubricants, plasticizers, and surfactants. It is also used as an additive in various industries such as pharmaceuticals, cosmetics, and food production.
When rubber materials come into contact with butyl stearate, issues related to the plasticization of the rubber can occur. This can include reduced tensile strength, increased flexibility or elasticity, and decreased hardness of the rubber. Additionally, exposure to butyl stearate can lead to discoloration of the rubber, as well as corrosion of the rubber due to the chemical reaction between the butyl stearate and the rubber material.
