Rubber Accelerator DPG (D) Identification: Chemical Name: Diphenyl guanidine Synonym: N,N-Diphenylguanidine; Vanax DPG; 1,3-Diphenylguanidine; Acelerator DPG; DPG; Accelerator D CAS NO.: 102-06-7 Structural Formula: Molecular Formula: C13H13N3 Properties: Grayish-white powder(granule)No taste, no poison. Density is 1.08--1.19. Soluble in acetone, ethyl acetate, benzene, alcohol, slightly soluble in CCl4; Insoluble in water and gasoline. Specification: Item Powder Oiled powder Granule Appearance Gray-white powder(granule) Initial M.P. ℃ ≥ 145.0 145.0 145.0 Loss on drying % ≤ 0.30 0.50 0.30 Ash % ≤ 0.30 0.30 0.30 Residue on 150μm sieve % ≤ 0.10 0.10 \ Granule Diameter mm \ \ 1.50 Application: Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process. Packing& Storage: In 25kg bag .Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
