Anti-swelling Additive for Methanol Gasoline
I. Product introduction:
Anti- rubber swelling additive for methanol gasoline is produced by compound mixture of efficient surfactant, low and high temperature antioxidants, rust protection agent, dispersing agent and selected cosolvent by certain proportion, and can be added to methanol gasoline by certain proportion. It has excellent anti-wear performance, excellent oxidation resistance and excellent corrosion resistance. It can prevent the wear and corrosion of relevant sealed parts of vehicles, maintain the elasticity of rubber parts so as not to be aged, and maintain long stability of the gasoline without any leakage. It also has the functions of improving power performance of vehicles and reducing oil consumption.
II. Product characteristics:
1. This product, with the convenience of applying, can be directly added to methanol gasoline and can be directly applied to all automobiles without the need to change rubber parts.
2. This product has an evident effect of anti-rubber swelling performance because all of the components in its formula have sulfoacid polar groups, which have strong surface activity by virtue of the structure composed by oleophilic non-polar groups and alcohol-philic polar groups, and these sulfoacid polar groups can impose strong absorption reaction upon the solid rubber surface, and formulate a firm protective film, and when it absorbs, the sulfoacid polar end absorbs on the rubber surface with the non-polar end connecting outwards to the methanol gasoline, and thus it can prevent the invasion of methanol gasoline and accomplish the goal of reducing rubber swelling.
