Applications

Primary material for standardizing acids. Diphenylguanidine is used as a medium of natural and synthetic rubber accelerator. It acts as a complexing agent for the detection of metals and organic bases. Further, it is used as a secondary foam stabilizer in the silicoflouride foam process. It is actively involved in the manufacture of rubber sheet, rubber shoes and other rubber industrial products.
