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
select accelerators for rubbers (zmbt) 2-mercaptobenzothiazole,select accelerators for rubbers. 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. explore the classification of accelerators, the
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).

- 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 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.
- Which thiuram accelerator is best for vulcanization?
- ETU and thiurams: Thiuram accelerators, such as TMTD (Tetramethylthiuram Disulfide) and TMTM (Tetramethylthiuram Monosulfide), when combined with ETU, can enhance the vulcanization process and improve aging resistance.
