ethylene thiourea wikipedia
ethylene thiourea (etu) is an organosulfur compound with the formula c3h6n2s.it is an example of an n,n-disubstituted thiourea.it is a white solid. it is synthesized by treating ethylenediamine with carbon disulfide.[3]ethylene thioureas are an excellent accelerant of vulcanization of neoprene rubbers..
new-generation curative taking an etu replacement accelerator from,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.
a safer alternative replacement for thiourea based accelerators in the
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).
quickly and safely getting up to speed - cordis.ethylene thiourea (etu)-based accelerators have been the industry standard for speeding the vulcanisation process (acting as an accelerator). however, etu has now been classified as a suspected human carcinogen by various eu bodies. its use is expected to be.

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.
ethylene thiourea c3h6n2s cid 2723650 rubber accelerator,ethylene thiourea is used as an accelerator in synthetic rubber production and as a curing agent for epichlorohydrin elastomers. ethylene thiourea is also a component of ethylenebisdithiocarbamate fungicides.
- What is ETU (ethylene thiourea)?
- When engaging in commercial procurement, prioritize quality assurance, regulatory compliance, appropriate packaging, and technical support to ensure optimal results in rubber product manufacturing. ETU (Ethylene Thiourea), also known as NA-22, is a widely used rubber accelerator that plays a crucial role in the production of rubber products.
- Can Ethylene thioureas be used to vulcanize neoprene rubber?
- Ethylene thioureas are an excellent accelerant of vulcanization of neoprene rubbers. In commercial use is the N,N'-diphenylethylenethiourea. Due to reproductive toxicity, carcinogenicity, and mutagenicity, alternatives are being sought to the ethylenethioureas. One candidate replacement is N-methyl-2-thiazolidinethione.
- 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:
- Can ethylene thiourea be used as a biomarker?
- Ethylene thiourea can be used as a biomarker of exposure to ethylenebis dithiocarbamates (EBDTCs), which are frequently employed as fungicides in agriculture, mainly on fruits, vegetables and ornamental plants. EPA (United States Environmental Protection Agency) has classified ethylene thiourea as a Group B2, probable human carcinogen.
- 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.
- Is ethylene thiourea a carcinogen?
- EPA (United States Environmental Protection Agency) has classified ethylene thiourea as a Group B2, probable human carcinogen. Ethylene thiourea has been shown to be a potent teratogen (causes birth defects) in rats orally or dermally exposed.
