ZDTP-50

Characteristics and Applications

An eco-friendly vulcanization accelerator for natural and synthetic rubbers, boasting excellent dispersibility during compound mixing. It features a slow vulcanization rate, good scorch safety, high crosslinking degree and no bloom. No nitrosamines are generated during vulcanization. The resulting vulcanizates possess good heat resistance and low compression set. It is generally used in combination with dithiocarbamate, thiuram or sulfenamide accelerators. When employed to improve reversion resistance, the dosage shall be carefully controlled to achieve a favorable balance between scorch safety and anti-reversion performance. It is suitable for automotive weatherstrips, cable sheaths, and translucent fast-curing natural rubber shoe soles.
