Application of Silane in Green Tires

The automotive industry is constantly seeking ways to improve fuel efficiency and reduce emissions. One of the key technologies enabling this is the use of silane coupling agents in "green tires".

What are Green Tires?

Green tires are designed to have lower rolling resistance compared to traditional tires. Lower rolling resistance means the engine doesn't have to work as hard to move the vehicle, resulting in better fuel economy and lower CO2 emissions.

The Role of Silane

Silica is used as a reinforcing filler in tire treads to reduce rolling resistance. However, silica is hydrophilic (water-loving) and does not mix well with rubber, which is hydrophobic (water-hating). This is where silane coupling agents come in.

Silanes act as a bridge, chemically bonding the silica to the rubber polymer. This improves the dispersion of silica within the rubber matrix, leading to:

• Reduced rolling resistance
• Improved wet grip (safety)
• Enhanced durability

As regulations on vehicle emissions tighten globally, the demand for high-performance silanes for green tires is set to increase significantly.
