DELTA H is a type of hydrocarbon oil used in automotive and industrial applications. It is commonly used as a lubricant and coolant, as well as a solvent for cleaning and degreasing. Common uses of DELTA H include lubricating the seals and other components of engines, transmissions, and other automotive systems, as well as providing a seal between moving parts in industrial equipment.
When exposed to DELTA H, rubber materials can experience swelling, softening, and chemical attack. Swelling of the rubber material can occur due to the hydrocarbons in the oil, resulting in an increase in volume and a decrease in tensile strength. Softening of the rubber material can occur due to the leaching of plasticizers, resulting in a decrease in the rubber's hardness and a decrease in its ability to resist abrasion. Chemical attack of the rubber material can occur due to the presence of oxygenated compounds in the oil, which can cause degradation of the rubber material due to oxidation.
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.
