Novel accelerators for synthetic polyisoprene and carboxylated nitrile latices
K B Chakraborty and R Couchman, Robinson Brothers Limited, UK
Unlike Natural Rubber latices Synthetic Polyisoprene and Carboxylated Nitrile latices are free from natural proteins and do not exhibit TypeI allergic reactions. However they are usually vulcanised with traditional Dithicarbamate and Thhiuram based accelerators. These are the precursors to Type IV skin allergy, potentially carcinogenic nitrosamines and contact discoloration.
