Rubber & Tire

Umicore produces a wide range of cobalt carboxylates that are used as Rubber Adhesion Promotors (RAP’s) in tires or other rubber applications.

Umicore has become a preferred supplier of cobalt hydroxide, cobalt chloride or cobalt sulphate to many RAP manufacturers. Thanks to our high quality products, related services and competitive pricing, we have grown over the past years to become one of the leading suppliers of these intermediate products.
