The performance of rubber products is heavily influenced by the quality and characteristics of their constituent materials. Among these, carbon black is a fundamental component, primarily known for its reinforcing capabilities. However, advancements in processing technologies have led to the development of specialized carbon blacks that offer additional benefits. One such advancement is the use of high-temperature oxygen-screening, a technique that refines carbon black to yield properties crucial for enhancing rubber product longevity. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of utilizing such advanced materials.

High-temperature oxygen-screening treatment involves processing carbon base materials at elevated temperatures in the presence of oxygen. This process effectively removes volatile organic compounds (VOCs) and other undesirable low-molecular-weight substances from the carbon material. The result is a carbon black with significantly reduced volatile matter, lower sulfur content, and diminished ash content. These refined characteristics are highly beneficial for rubber applications. For instance, a cleaner carbon black can lead to improved electrical properties in certain compounds, and reduced volatiles contribute to a cleaner manufacturing process and a more stable final product.

When incorporated into rubber formulations, carbon black processed through this method offers several advantages that contribute to extended product longevity. The reduced volatile matter leads to a more stable compound, less prone to premature degradation or changes in physical properties over time. Furthermore, the low sulfur and ash content ensure that the carbon black acts primarily as a reinforcing agent without introducing impurities that could compromise the rubber’s performance or durability. This is particularly relevant when considering materials as a rubber product service life enhancer.

The refined structure and purity of high-temperature oxygen-screened carbon black also contribute to improved mechanical properties, such as tensile strength and tear resistance. These enhanced properties are critical for rubber components that experience significant stress or wear, such as in tires, hoses, and seals. By providing superior reinforcement, this type of carbon black helps the rubber withstand these forces, thereby increasing its lifespan. Coupled with additives that provide air retention and anti-ozone protection, it forms a powerful combination for demanding applications. For instance, incorporating an effective tyre air retention additive alongside such carbon black can significantly boost tire performance.
