Usage

General Description

Di(thiocyanic acid)4,4'-iminodiphenyl ester, also known as BPTI, is a chemical compound used as a curing agent in the processing of rubber. It is a white to light yellow powder with a strong odor. BPTI is primarily used in the production of rubber goods such as tires, conveyor belts, and hoses. It acts as an accelerant in the vulcanization process, aiding in the cross-linking of rubber molecules and improving the mechanical properties and stability of the final rubber product. BPTI is also known to have potential skin and eye irritant properties, and should be handled with care in accordance with safety guidelines.
