Carbon-Black Reinforcement of Adhesives and Sealants

2000/7/27· The interaction between carbon black and the polymer, therefore, results in a loss of preferred conformation, conceivably because the polymer forms a strongly absorbed surface layer. From the infrared data, it appears that a high-structure carbon black such as XC72R can be absorbed on the elastomer surface and promote mostly trans conformation for the rubber structure.

Clariant Additive Masterbatch Makes Black Plastic …

New Clariant CESA®-IR additive masterbatches are now available to make dark-colored plastics visible to the near-infrared (NIR) sensors used in automated polymer sorting systems. While many companies use black packaging to brand their prestige products, the problems it poses in recycling systems has led to calls for black to be phased out of the palette. The new masterbatches help to resolve

Ketjenblack EC-600JD Electroconductive carbon black

Ketjenblack EC-600JD is a very pure carbon black extremely suitable for antistatic and electroconductive appliions. Due to its unique morphology and the extremely high surface area of approx. 1400 m2/g (BET), only one sixth the amount of Ketjenblack EC600-JD is needed compared to conventional electroconductive blacks in order to achieve the same conductivity.
