Petroleum oil, also known as mineral oil, is a hydrocarbon based oil derived from petroleum. It is commonly used as a lubricant and coolant in industrial and automotive applications, as well as in the production of rubber and plastic parts, paints, varnishes, and coatings.
At temperatures below 250°F, rubber can become soft and pliable, making it more prone to tearing and other physical damage. Additionally, petroleum oil can cause rubber to swell, leading to sealing failure and deformations in rubber parts. In extreme cases, petroleum oil can also cause chemical degradation of rubber, leading to cracking, hardening, and eventual failure.
Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. Viton ® is also known as FKM made of fluoroelastomer one of the most versatile and widely used sealing materials.
