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).
consortium-develops-alternative-to-thiourea rubber news,brussels, belgium—the saferubber research consortium has come up with a safer alternative accelerator to ethylene thiourea for the vulcanization of chloroprene rubber. the consortium said it has developed a new molecule, codenamed srm102, which it cites.
- 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.
- 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 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 & 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.
- 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.
