Use Characteristics HiDispersion ZDEC-80 causes very rapid vulcanization of natural and synthetic rubbers, e.g. SBR, NBR and EPDM. The addition of thiuram and thiazole accelerators can retard the start of the vulcanization and, at the same time, increase processing safety. ZDEC-80 provides a longer scorch time and a faster total curing rate than ZDBC-80. HiDispersion ZDEC-80 recieves an additional activation from basic accelerators. HiDispersion ZDEC-80 is also used in small amounts for secondary acceleration and activation of mixes which are going to be cured with mercapto or thiuram accelerators. HiDispersion ZDEC-80 gives very good tenslie and resilience properties. For improving the resistance to ageing especially of NR and IR it is recommended to add antioxidants.
Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ZDEC is assured.
