Accelerator DPG

Trade name: Accelerator DPG
Chemical name: Diphenyl guanidine
Packages: bags 25 kg net weight

DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and other thiazoles. It is a strong secondary for CBTS, TMTM, TMTD, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. Fatty acids in excess of 1% decrease tensile and tear strength properties. DPG does give satisfactory processing safety and storage stability to rubber compounds. In light colored goods, it causes a brown discoloration and is not recommended for use in compounds that have contact with food. Vulcanizate properties of stress (modulus) are high, however elongation decreases with an increase in cure time. For best aging results, an antioxidant is required.
