  • What is CIIR vulcanization?
  • CIIR is copolymer of chlorinated isobutylene and small amounts of isoprene which provides unsaturated sites for vulcanization. the chlorinated sites are more reactive, providing faster cure with lower amount of curatives and better adhesion to unsaturated rubbers and metals.
  • Why is IIR a good vulcanizer?
  • IIR is a copolymer of isobutylene and small amounts of isoprene, which provide the unsaturated sites for vulcanization. It has unusually low gas permeability and outstanding resistance to UV, oxygen and ozone attack. Due to the low content of unsaturated bonds, it also has excellent chemical resistance and thermal stability.
  • What is the role of thiazole in vulcanization?
  • It also functions as curing agent for vulcanization without free sulfur or low-sulfur. It is used as a primary accelerator in the presence of sulfur and as a secondary accelerator with thiazoles and sulfenamide. It produces reversion persistent vulcanizates with good aging characteristics.
