Application and characteristics:
Application:
dibenzamido diphenyl disulphide(Peptizer or Peptiser DBD) is a pure chemical peptizer for pure gum mastication, through which natural rubber (NR) is processed without carbon black at normal and higher temperatures.
Peptizer or Peptiser DBD A82: Viscosity reduction of natural rubber by means of chemical cleavage of polymer molecules; Faster distribution due to higher dispersion content; Effective on open mills from 80 °C and in internal mixers up to 160 °C
Peptizer or Peptiser DBD A86: Optimum balance of viscosity reduction and batch uniformity; Design focused on high efficiency together with excellent dispersion;
Peptizer or Peptiser DBD A89: Highest available rate of efficiency; Very fast chemical chain scission during mastication; Effective at very low dosage
Package and storage:
25kgs/drum as customer’s request
Store it in dry,cool well-ventilated and shady place.
