DCBS-80

Characteristics and Applications

A delayed-action accelerator for natural and synthetic rubbers, featuring excellent dispersibility during rubber compound mixing. It provides long scorch time and high processing safety, making it suitable for thick articles and compounds loaded with high levels of active reinforcing fillers. The vulcanizates exhibit good dynamic performance, high elasticity and high modulus at specified elongation. Among sulfenamide accelerators, it delivers the best adhesion to brass-plated steel cord. It is not suitable for the production of food-contact articles. It is mainly used for steel-cord high-pressure rubber hoses and large, thick, metal-reinforced rubber vibration isolators (e.g., bridge bearings, heavy-duty truck vibration pads).
