ALKANES Chemical compatibility with O-rings, rubbers, & plastics

Alkanes, also known as paraffin hydrocarbons, are a group of saturated hydrocarbons with the general formula CnH2n+2. They are characterized by single bonds between carbon atoms and include compounds such as methane, ethane, propane, and butane. Alkanes are found in natural gas, petroleum, and various fossil fuels. They are used as fuels, solvents, and as raw materials in the chemical industry. Alkanes are relatively non-reactive and stable but are highly flammable, requiring careful handling and storage to prevent fire hazards. Proper ventilation, use of personal protective equipment (PPE), and adherence to safety guidelines are essential when working with alkanes.
