Product Description: Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides 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 (imparts bitter taste). For best aging results, an antioxidant is required. Suggested dosages of DPG in combination with zinc oxide, stearic acid, and sulfur are as follows:
Natural Rubber: 0.10- 0.50 phr with sulfenamides or MBTS
SBR: 0.20 - 0.75 phr with sulfenamides, MBTS or MBT
NBR: 0.20 - 0.50 phr with CBTS, MBTSInformation provided by Akrochem Corporation |
