Fast Accelerator
1.Safe,environmentally friendly,producing no nitrosamines,no staining,no blooming and low cost.
2. Perform well in Nr and EPDM,over dosage won't cause blooming.
3. Non-amine based structure,can be used in non-N-nitrosamine generating cure systems,substituting TMTD.
4. Make rubber product with good thermal-aging resistance and curing reversion resistance.
Application 1.ZBPD can be used in NR and EPDM at levels of 1.0 to 4.0 phr (base on pdr-75%)as a secondary accelerator
in combinations with sulfenamides,thiazoles and thiurams.
2. When used in NR to improve reversion resis-
