Whilst carbon black is the most commonly used material for reinforcing rubber in tyres, there are some alternative materials that can be used or combined with carbon black to achieve different properties or benefits. Some of these materials include:
Silica: Silica is a mineral that can be used as a reinforcing filler in tyres, either on its own or in combination with carbon black. Silica has been shown to improve the fuel efficiency of tyres by reducing rolling resistance, which can lead to lower carbon emissions and improved mileage.
Natural rubber: Natural rubber is the traditional material used to make tyres, but it is less commonly used today due to its high cost and limited availability. However, natural rubber has some advantages over synthetic rubber, such as superior elasticity, durability, and tear resistance.
Soybean oil: Soybean oil is a renewable resource that has been used as a replacement for petroleum-based oils in tyre manufacturing. Soybean oil can improve the tyre’s flexibility and resistance to wear, tear, and aging.
Nanocellulose: Nanocellulose is a material made from plant fibres that can be used as a reinforcing filler in tyres. It has been shown to improve the tyre’s strength, durability, and resistance to wear, tear, and deformation.
It’s important to note that each of these alternative materials has its own set of advantages and disadvantages, and their use in tyre manufacturing is still relatively limited compared to carbon black. However, ongoing research and development in this area may lead to new and innovative materials that can provide even greater benefits to tyre performance and sustainability.
