CHOLESTEROL Resistant O-Rings and Seals
Cholesterol is a type of lipid molecule that is essential for the proper functioning of the body and is found in the bloodstream. It is also known as a sterol and is found in foods such as eggs, butter, and cheese. Common uses for cholesterol include hormones, vitamins, and cell membranes.
When rubber is exposed to cholesterol, it can cause swelling, cracking, and discoloration of the rubber material. Over time, the rubber material can become brittle and lose its elasticity, leading to premature failure. Additionally, exposure to cholesterol can cause the rubber material to become brittle and lose its adhesive qualities, which can result in a decrease in the seal’s effectiveness.
