Transparent Rubber

CAB-O-SIL® fumed silicas are designed to improve performance in clear rubber applications by providing a high level of reinforcement and transparency.

Our CAB-O-SIL M-5KD and CAB-O-SIL M-6KD fumed silicas enable customers to manufacture colorless, highly transparent rubbers which can be used in a variety of applications, including clear shoe soles. Our CAB-O-SIL fumed silicas when incorporated in a polybutadiene rubber (BR), styrene butadiene rubber (SBR) and isoprene rubber (IR) blends deliver the optical clarity, mechanical properties and processability needed to facilitate the performance requirements of sneaker outsoles.

Based on internal studies, both silicas provide superior clarity over precipitated silica in BR/SBR/IR blends and deliver high transmission and low haze values. Our fumed silicas can also produce translucent or even clear, non-yellowing rubber products with minimal aging effect, making them ideal additives for clear rubber applications.
