Continental Carbon promotes eco-friendly carbon black According to a Lucintel survey, the 2018

Thus, Continental Carbon has developed its ultra-clean JE88 carbon black, with the grit value controlled at 10-30 ppm. In addition to better purity, compared to the granular N550 carbon black, Continental Carbon says it has also improved the carbon black pelletising technology to reduce the hardness of granules. Compared to N550, JE88 features the following advantages: • Improving process efficiency and enhancing reinforcement When mixing carbon black and rubber, the mixer must first pulverise rubber and carbon black granules. The lower the hardness of carbon black granules, the easier it is for pulverisation. In addition to saving mixing time and improving process efficiency, it allows for a more even distribution of carbon black in the rubber and better reinforcement.

specialty carbon black market reached

US$1.8 billion. Due to its increased demand in the construction, building, packaging,

automobile industry, plastic, and coating sectors, the figure is expected to reach US$2.5 billion in 2022. Against this

backdrop, Taiwan’s Continental Carbon is expanding its product reach.

T

he huge growth of the carbon black market has attracted major carbon black proprietors to engage in specialty carbon black product research, taking an active approach towards seizing the opportunities presented in the market. The only carbon black manufacturer in Taiwan, Continental Carbon, a business affiliated to the CSRC Group, ranks sixth globally in terms of capacity, and operates bases in the US, Asia, India, and Europe. The firm says it has long been committed to R&D and the active development of specialty carbon black products, having recently introduced its ultra-clean JE88 carbon black.

• Replacing N550 to enhance product yield The physical and chemical properties of JE88 are comparable to those of N550. For rubber products with high purity and yield requirements, JE88 can directly or partially replace N550, without any changes to the product formula as a result of the carbon black replacement. The higher purity will then ensure a substantial increase in yield. • Reduced process costs and a wider range of applications JE88 has a low impurity content, making application on product surfaces purer, with a wider range of rubber applications. At the same time, it decreases the speed of extruder plugging and reduces the number of screen replacements, thus greatly reducing processing costs. Other features are its excellent colouration, allowing it to be applied in cable insulation shield materials. Its high-purity characteristic makes it an excellent additive for high-grade rubber products, providing rubber products with good reinforcement, abrasion resistance, and flexibility.

Advantages of non-grit JE88 Grit in carbon black is an impurity. It cannot be mixed with rubber and does not display reinforcing effects, and it also affects the colouration and rubber performance. Thus, the first goal of carbon black manufacturers is to reduce the impurity content.

R&D vital for new product development In recent years, Taiwan’s Ministry of the Economic of Affairs has actively promoted high value-added petrochemical industry projects, in the hope that while researching and developing high value-added petrochemical products, a circular economy can also be implemented. Specialty carbon black featuring high purity, better dispensability, and outstanding colouration competency not only enables it to achieve better performance in rubber product applications, but also reduces the cost of the industrial processes, increasing process efficiency and environmental friendliness, says Continental Carbon.

JE88 carbon black can be applied in a variety of applications
