classification of rubber vulcanizing accelerators based on,because the rubber vulcanizing accelerator has a great influence on the vulcanized rubber characteristics, it is necessary to classify and identify the three popular types of rubber vulcanizing accelerators to avoid using the wrong accelerator during tire production and to ensure the tire quality.

cure characteristics, swelling behaviour and tensile

(etu) are widely utilised as curative additives for polychloroprene rubber (cr) [2-3]. both of the metal oxides are utilised as curing agents and etu as the curing accelerator. etu is a toxic material and is suspected to be carcinogenic [4-5] and hence, an appearance of an alternative curing accelerator for cr has been in demand.

new-generation curative taking an etu replacement accelerator

pounding, polychloroprene, epichlorohydrin, ethylene-acrylic elastomer, svhcintroductionethylene thiourea (etu) is an accelerator which has been widely used for many years in polychloroprene and epichlorohyd. in rubber compounding to produce fast-curing, heat-resistant compounds that process well. however, this material is classified as cmr

factory supplier rubber accelerator etu,erj staff report (bc) brussels the saferubber research consortium has come up with a safer alternative accelerator to ethylene thiourea (etu) for the vulcanisation of chloroprene rubber. the consortium has developed a new molecule, codenamed srm102, which it cites as a suitable candidate to replace etu in compounding, cable manufacturing

a safer alternative replacement for thiourea based cordis,however all of the trials carried out indicate that the proportion of etu and srm102 used in the formulas for all the end users is very similar i.e. around 1% , therefore the current cost estimates of the accelerator srm102 will not increase the manufacturing cost of a final rubber compound more than 105% of the equivalent compound made using etu.
