This part is about percentage of carbon black in tyres.

Carbon black is a critical component of tires and plays a significant role in enhancing their performance and durability. It is a form of elemental carbon produced by the incomplete combustion of hydrocarbons. Carbon black is commonly added to the rubber compound during the tire manufacturing process due to its unique properties and benefits.

The percentage of carbon black in tires typically ranges from 10% to 30% by weight. The exact amount depends on various factors, including the desired tire characteristics, performance requirements, and the type of tire being produced. Higher percentages of carbon black are often used in tires that require enhanced traction, wear resistance, and overall durability.

One of the primary functions of carbon black in tires is to reinforce the rubber matrix. It improves the mechanical properties of the tire, such as its tensile strength, tear resistance, and abrasion resistance. Carbon black particles form a network within the rubber, increasing its stiffness and preventing the rubber from deforming under stress. This reinforcement helps tires withstand the forces experienced during vehicle operation, leading to improved safety and longevity.

Carbon black also plays a vital role in the tire's performance on the road. It provides the necessary grip or traction by increasing the tire's surface area in contact with the road. This property is particularly crucial for tires used in wet or icy conditions, where maintaining traction is essential for vehicle control and stability.

Furthermore, carbon black helps dissipate heat generated during tire operation. As the tire rolls and flexes, heat is produced due to the deformation of the rubber. Carbon black acts as a thermal conductor, allowing the heat to spread throughout the tire and prevent localized overheating, which can lead to tire failure.

Types of carbon black used in tires

This part is about the types of carbon black used in tires.

There are several types of carbon black used in the production of tires, each offering unique properties and benefits. These types differ in terms of their particle size, structure, and surface characteristics, which directly influence the performance of the tires. The following are some of the commonly used types of carbon black in tires:

Furnace Black: Furnace black is the most widely used type of carbon black in tire manufacturing. It is produced through the combustion of hydrocarbons in a furnace, resulting in fine particles with a complex structure. Furnace black provides excellent reinforcement, tear resistance, and abrasion resistance to tires.

Channel Black: Channel black is produced using a different manufacturing process compared to furnace black. It has a lower structure and larger particle size, which gives it a unique combination of properties. Channel black is often used in low rolling resistance tires, as it helps reduce energy loss and improve fuel efficiency.

Thermal Black: Thermal black is a high-structure carbon black produced by the partial combustion of natural gas. It has a unique morphology that provides good reinforcement and high resilience to tires. Thermal black is commonly used in high-performance tires that require superior traction and handling characteristics.

Acetylene Black: Acetylene black is a premium-grade carbon black manufactured by the thermal decomposition of acetylene gas. It has a small particle size and a high degree of structure, which gives it excellent reinforcing properties. Acetylene black is primarily used in high-end tires, such as those designed for sports cars or racing applications.

Lamp Black: Lamp black is a type of carbon black produced by burning oils or resins. It has a relatively low structure and large particle size, making it suitable for specific tire applications. Lamp black is commonly used in white sidewall tires to provide a contrasting appearance.

The price of carbon black used in tires can vary depending on several factors, including global supply and demand, production costs, market conditions, and the quality and type of carbon black. As of my knowledge cutoff in September 2021, the price of carbon black ranged from approximately $800 to $1,500 per ton.

The production of carbon black involves complex processes, such as the combustion of hydrocarbons and subsequent purification steps. These processes require energy and raw materials, which contribute to the overall production costs. Additionally, factors like the availability of feedstock, transportation costs, and environmental regulations can influence the price of carbon black.

Another crucial factor affecting the price is the type and quality of carbon black. Premium-grade carbon blacks, such as acetylene black or high-performance specialty blacks, tend to have higher prices due to their superior properties and limited availability. On the other hand, standard carbon blacks, such as furnace black, are more widely produced and generally have a lower price range.

Market conditions and global supply and demand dynamics also impact the price of carbon black. Fluctuations in the oil and gas industry, which serve as feedstock sources for carbon black production, can influence prices. Additionally, factors like economic growth, tire manufacturing trends, and environmental regulations in different regions can affect the demand for carbon black and subsequently impact its price.

It is important to note that the price of carbon black can change over time due to market dynamics and other external factors. Therefore, the specific price per ton at any given time may differ from the information provided here. It is recommended to refer to current market reports and industry sources for the most up-to-date information on carbon black prices.

Carbon black from waste tyres

This part is about carbon black from waste tyres.

Carbon black can also be obtained from waste tires through a process known as pyrolysis. Pyrolysis involves the thermal decomposition of tires in the absence of oxygen, leading to the production of various by-products, including carbon black. This method provides an opportunity to recycle and reuse the carbon black present in waste tires, reducing environmental impact and promoting sustainability.

The pyrolysis process begins by shredding the waste tires into smaller pieces. These pieces are then heated in a controlled environment, typically in a reactor, where they undergo thermal decomposition. As the tires are heated, the complex organic compounds break down, releasing gases and oils. The gases are often captured and used as a source of energy in the pyrolysis process, making it more efficient and self-sustaining.

The solid residue left after the pyrolysis process is known as pyrolytic carbon black or rCB (recovered carbon black). It has properties similar to commercially produced carbon black and can be used as a substitute in various applications, including tire manufacturing, rubber products, coatings, and plastics.

The utilization of rCB offers several environmental and economic advantages. Firstly, it helps divert waste tires from landfills, reducing the accumulation of tire waste and the associated environmental hazards. Additionally, recycling carbon black from waste tires reduces the demand for virgin carbon black, which is typically produced from fossil fuels. This, in turn, decreases carbon emissions and the consumption of non-renewable resources.

Moreover, the use of rCB can provide cost savings, as it is often more cost-effective compared to virgin carbon black. This makes it an attractive option for manufacturers seeking to reduce production costs without compromising on product quality.

However, it is important to note that the quality and characteristics of rCB obtained from waste tires may vary depending on the pyrolysis process parameters and the tire composition. Some challenges associated with rCB include variations in particle size, impurities, and potential differences in performance compared to virgin carbon black. Therefore, proper quality control measures and testing are crucial to ensure the suitability of rCB for specific applications.
