Acmecure DPG

Chemical Name Diphenylguanidine

Supply Form Greyish White Powder
Major Application Accelerator For Rubber

These are seldom used alone as they give very slow vulcanization reaction. They are used as secondary accelerator(booster) for Mercapto & Sulphenamide accelerators in NR, NR/BR OR SBR/BR blend based compounds in tread or equivalent compounds. Acmecure DPG & Mercure Thiazole accelerators (MBT & MBTS) boost each other in an extraordinary manner with regard to the rate of cure & degree of crosslinking, their effect being synergistic. Hence this combination is preferred when goods are cured in hot air giving faster and excellent plateau. They have good mechanical properties and better resistance to ageing. When alone, they give slow onset of cure therefore specially used for curing thick articles. In Latex foam these are used as secondary gelling agent.
