Cabot Corporation has expanded what is possible in transparent rubber products derived from polybutadiene (BR), styrene butadiene (SBR), and isoprene (IR) rubber blends. 

CAB-O-SIL fumed silicas are designed to improve performance in clear rubber applications by providing a high level of reinforcement and transparency and enables manufacturing of colorless, highly transparent rubbers - perfect for athletic footwear outsoles.

In IR/BR/SBR rubber blends, CAB-O-SIL® M-6KD and CAB-O-SIL® M-5KD fumed silica demonstrate superior performance relative to precipitated silica. Benefits include:

Optical Clarity

  • Higher transmission values indicating a better see-through property
  • Lower haze values indicating minimal light-scattering and thus superior clarity
  • Clear, translucent, non-yellowing rubber products with minimal aging effect  

Mechanical Properties

  • Superior reinforcement (high tensile strength and elongation-at-break) without making the rubber too hard for sneaker outsoles

Processability

  • Comparable processability to other silicas during the entire mixing process
