About Activators– Magnesium Oxide

High-active Magnesium Oxide functions as a reactive activator in rubber, adhesive and sealant formulations where curing efficiency, acid neutralisation and processing stability are important. Its high purity and fine particle structure support good dispersibility and reactivity, helping accelerate vulcanisation, improve adhesion and regulate acidic components within the system. In rubber compounds and synthetic rubber adhesives, it also contributes to cross-linking efficiency, heat resistance and overall formulation stability.
