Liquefied Petroleum Gas (LPG) is a byproduct of natural gas processing and oil refining, and is most commonly used as a fuel for heating, cooking, and vehicle fuel. It is also used in a variety of industrial applications including aerosol propellants, refrigerants, and chemicals production.
Rubber materials can be affected by LPG due to its high vapor pressure. Exposure of rubber materials to LPG can lead to swelling, softening, cracking, and other mechanical failures. At high temperatures, the rubber may become brittle and brittle fracture may occur. Additionally, elastomers may experience reduced tensile strength, tear strength, and abrasion resistance when exposed to LPG.
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.
