Presnets a Meeting entitled:
"High Performance Environmentally Safer Accelerator for Elastomers"
Introduced by Dr. K B Chakraborty and T D Stephens, Robinson Brothers Ltd
Robac SAA30 is a recently developed ultra fast environmentally safer vulcanisation accelerator. It has major application in dry rubber compounding (NR, SBR, NBR and EPDM) as a primary or secondary accelerator, capable of replacing established thiurams or dithiocarbamates on a weight to weight basis with superior vulcanisate properties.
Robac SAA30 works best in a Semi-EV System (Sulphur 1-1.5 phr) and confers a high rate and state of cure with minimum reversion combined with a hitherto unobtainable combination of dynamic and thermal stability. It can be used both at low temperature and high temperature cure without the loss of desirable properties of the vulcanisates.
Mechanistic studies have indicated that it can efficiently utilize elemental sulphur in the cross linking reaction and produces predominantly relatively stable disulphide cross links whilst binding within the network, contributing to the overall stability of the network and resisting extractive media.
