Efficient density determination for rubber compounds

| By Mary Page Bailey and Gerald Ondrey

Within rubber production facilities, density is an important process parameter that correlates with the degree of cross-linking or the hardness of the elastomer used. The determination of the density is therefore of great importance for the development of recipes and quality control. The ElaTest measuring system (photo) is designed for density determination of non-vulcanized (uncured) rubber and rubber compounds. With its rapid measuring method, integrated scale and robust design, the ElaTest system is suitable for challenging applications, such as tire manufacturing. — Brabender GmbH & Co.
