carbon black for rubber and tires helps to conduct heat away from the tread and belts of the tires, which also helps to increase the lifespan of the tire. The carbon black compounds also help protect the tires from UV rays and ozone, which can shorten the lifespan of tires.Other industrial rubber applications for Carbon Black are molded and extruded products. The other 10 per cent of vCB is used for UV absorption, as a conducting agent in plastics, inks, and coatings, or as a pigment.

 

carbon black for rubber grades are the most widely used and cost-effective rubber reinforcing agent in tire components, mechanical rubber goods, including industrial rubber goods, membrane roofing, automotive rubber parts and other rubber goods.

 

 

Our range of high-performance carbon blacks enables compounders and rubber goods manufacturers to exceed their customer’s requirements for excellence in processing, surface finish appearance and product durability. Crown Carbon solutions meet the unique needs of applications including weather strip, belts, hoses and anti-vibration components among the many and varied rubber goods applications. Our carbon blacks can play a significant role in your ability to tailor mechanical and electrical properties, fatigue life, mixing energy and rheology to give you a competitive edge in the markets you serve.

 

Carbon black is the predominant reinforcing agent used to improve the performance properties of elastomer-based composites in most rubber applications.

Our broad portfolio of carbon products are specifically designed for tires as well as automotive and non-automotive industrial rubber products.

We also offer innovative products that offer flexibility in elastomer formulation such as our engineered elastomer composites , pre-mixed composites that eliminate the need for costly and time-consuming evaluation of specific fillers and allow design times to move straight into final compound optimization.

 

Carbon black can be used in tire and rubber products reinforcement, It is pure black powder or ganular, and has high reinforcement capacity for rubber products and tire manufacture, and could increase rubber service life. Our company could custom produce carbon black products depend on customers requirement.

The largest volume of carbon black is used in rubber applications. It provides reinforcement and improves resilience, tear-strength, conductivity and other physical properties.

Furthermore, Crown Chemical has been developing carbon black with various combined functions for special applications.

Carbon Black for rubber ASTM grades can be divided into two categories: highly-reinforcing grades and semi-reinforcing grades.

– Hard blacks (synonyms: tread grades, reinforcing carbon black): a type of furnace carbon black having an average nitrogen surface area of 70 m²/g or greater.

– Soft blacks (synonyms: carcass grades, semi-reinforcing carbon black): a type of furnace carbon black having a nitrogen surface area in the range of 21 to 69 m²/g.
