Cabot introduces new carbon black with low PAH content

On Oct. 27, Cabot Corporation announced the launch of VULCAN® 3-LP carbon black, a new low polycyclic aromatic hydrocarbon (PAH) product for rubber applications. VULCAN 3-LP carbon black is the fourth product in the Cabot LP carbon black series, providing customers with a full suite of carbon black products for the use in applications that require a controlled, very low PAH content, such as consumer rubber goods as well as food and potable water contact applications.

VULCAN 3-LP is a pelletized reinforcing carbon black that is engineered for end-use rubber products that need a higher reinforcement, strength, abrasion and tearing resistance level than semi-reinforcing carbon blacks. The full Cabot LP carbon black series, including VULCAN 3-LP carbon black, is manufactured through a special process to yield a consistent, very low level of PAH that comply with the increasing regulatory requirements and quality certifications across the globe that limit the content of PAH in certain rubber applications and the carbon black used to prepare them.

Key application uses include:

  1. Consumer rubber applications, such as toys and childcare items, sporting equipment, housing items, tools, clothing and accessories

  2. Rubber products intended to be taken in the mouth or with foreseeable long and repeated short-term skin contact

  3. Rubber components that have direct contact with drinking water, including hoses and liners in drinking water systems and pipes and tanks

  4. Rubber products that have contact with food, such as gaskets, o-rings, seals and food transportation belts
