High Viscosity Lubricant H2 is also known as polyalphaolefin (PAO). It is a synthetic lubricant that is used in automotive and industrial applications due to its high viscosity and excellent resistance to oxidation. Common applications for this lubricant include engine oils, gear oils, and other automotive lubricants.
When rubber is exposed to High Viscosity Lubricant H2, it can cause swelling, reduced elasticity, and cracking. If the lubricant is exposed to the rubber for an extended period of time, it can also cause a decrease in the rubber's tensile strength, leading to further material degradation. Additionally, the rubber can become brittle, increasing the risk of cracking and 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.
