Get PriceWhat 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.
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:
Is ethylene thiourea flammable?
Ethylene thiourea (ETU) is an antithyroid substance and animal carcinogen. Ethylene thiourea is combustible. Non flammable Ethylene thiourea, a thiourea derivative, is a rubber chemical. It caused contact dermatitis mainly in rubber workers.
What is ethylene thiourea used for?
Ethylene thiourea is used extensively as an accelerator in the curing of polychloroprene (Neoprene) and other elastomers; as a vulcanizing accelerator in rubber processing; in electroplating baths. In addition, exposure to ethylene thiourea also results from the very widely used ethylene bisdithiocarbamate fungicides.
How is ethylene thiourea classified?
When needed, the Government implements risk management measures under CEPA 1999 and other federal acts to help prevent or reduce potential harm. The ecological hazard and exposure potentials of ethylene thiourea (ETU) were classified using the Ecological Risk Classification of Organic Substances (ERC) Approach.
What is ethylene bis-dithiocarbamate fungicide (ETU)?
ETU was originally included in the draft screening assessment for the Heterocycles Group. To better align with the re-evaluation of certain pesticides, this substance was assessed separately. ETU is a degradation product, metabolite and residual in ethylene bis-dithiocarbamate fungicides. ETU does not occur naturally in the environment.
