Standard Test Method for Evaluating the Effective Surface Area of Zinc Oxide in Rubber
Importancia y uso:
4.1 The surface area of zinc-oxide in rubber can significantly affect cure activation and vulcanizate properties.
4.2 The specific surface area of zinc-oxide is usually measured by nitrogen absorption which requires the use of equipment not normally found in rubber laboratories. This test method allows a ranking of zinc-oxide samples according to their surface areas with respect to a known standard using a simplified procedure involving mixing of rubber compounds and measuring cure times with oscillating disk or rotorless cure meters.
4.3 This test method may be used for quality control, research and development work, and comparison of different zinc-oxide samples.
