- What is a DBD peptiser?
- The dibenzamido diphenyl disulphide (DBD) chemistry used to produce the active ingredient within Pepton ® is widely considered by the rubber processing industry to be more environmentally acceptable than traditional pentachloro thiophenol based peptisers. Thomas Swan’s DBD is the only fully REACH registered chemical peptiser.
- How does DBD work?
- DBD works very well at elevated temperatures of 120oC and above in internal mixer and about 80oC in 2-roll mills, reducing the viscosity of rubber. DBD does not affect physical and ageing properties of rubbers. It is an environmentally friendly organic chemical peptizer for NR, SBR and other Diene rubbers.
- What is a good peptizer for rubber?
- Peptizer 66 is an effective chemical peptizers primarily used for natural rubber. Recommended dosage levels in natural rubber range from 0.05 to 0.5 phr (as final mixing temperature increases, the lower levels should be used). Synthetic rubbers require approximately 2.0 phr.
