rubber raw materials european rubber journal,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.
new-generation curative taking an etu replacement accelerator
etu shows that the new accelerator offers comparable basic physical properties in a general-purpose compound to etu. while the hot air aging properties of the srm102-containing compound do not match those of etu, they are comparable to clwyd’s current etu replacement (hexa/tmtd) and to other etu replacements available on the market.

- Which rubber accelerators are suitable for vulcanization?
- Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- What is ETU used for?
- ETU finds extensive use in the production of various rubber products, including: - Tires: It is commonly used in tire manufacturing to accelerate vulcanization, ensuring optimal performance, durability, and tread wear resistance.
- What types of rubber accelerators do you offer?
- We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators. Below is a rubber accelerators list of products that we offer.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
