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
rapid and sensitive lc ms ms determination of 2,2-mercaptobenzothiazole (mbt) is one of the most important vulcanization accelerators in the industrial production of rubber, especially car tires. given its wide use in household articles and industrial rubber products it has a high potential to migrate into the environment. humans can be exposed by dermal, oral, or inhalative routes. incorporated mbt is excreted in urine, mainly as
a safer alternative replacement for thiourea based cordis
ethylene thiourea (etu) has been used as accelerator in production of chloroprene rubber for decades. etu is classified as cmr (carcinogenic, mutagenic or toxic to reproduction) and is thereby a substance that could identified as a substance of very high concern and afterwards included in annex xiv of reach (authorisation).

in rubber manufacturing trials, srm102 was shown to be a viable replacement for etu. while technical viability is critical, commercialisation relies on the bottom line. since the percentage of srm102 required compared to rubber content is similar to that of etu, the new additive is expected to have minimal effect on the final manufacturing cost.

- What is ETU in chemistry?
- ETU is an organic compound belonging to the thiourea class of accelerators. It is a white crystalline powder with a faint odor. Chemically, it consists of an ethylene bridge connecting two thiourea functional groups. ETU is known for its high solubility in rubber and compatibility with various types of rubber. 2. Characteristics of ETU:
- What is an elastomer cure system?
- In this study, the focus will be on accelerators. In general, an elastomer cure system consists of zinc oxide, stearic acid, sulfur, and one or more accelerators. Cure systems are varied to alter the physical and mechanical properties of rubber compounds, and to change the processing at-tributes of a compound prior to being cured.
- What is ETU & sulfur?
- ETU and sulfur: This combination is widely used in tire manufacturing and other rubber applications, providing excellent vulcanization properties, aging resistance, and overall performance.
- Do accelerators affect elastomer curing properties?
- Every component added to a compound will have either a major or minor impact on curing properties; for-tunately these impacts are high-ly dependent on concentration. In this study, the focus will be on accelerators. In general, an elastomer cure system consists of zinc oxide, stearic acid, sulfur, and one or more accelerators.
