A Safer Alternative Replacement for Thiourea Based ... - CORDIS

Being classified as CMR, ETU is a substance that could be identified under REACH as a Substance of Very High Concern (SVHC) and therefor a potential candidate to be included in the Candidate List and later in Annex XIV of REACH (Authorisation). The REACH Regulation mentions (Q)SARs as a mean to provide data without doing animal testing.

etu (ethylene thiourea) rubber accelerator: characteristics

ETU (Ethylene Thiourea) Rubber Accelerator: Characteristics

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: - Acceleration: ETU functions as a primary accelerator, meaning it can initiate and speed up the vulcanization process in rubber

Vulcanization of Rubber - Science Notes and Projects

Acetoxysilane Urethane Vulcanization of natural rubber requires heat, but it¡¯s not an essential factor in all processes. For example, silicone vulcanization occurs at room temperature. Some processes use radiation instead of heat. Modern vulcanization often includes a chemical called an accelerator.

for ETHYLENE THIOUREA - CDC Stacks

Ethylene thiourea is used extensively as an accelerator in the vulcanization ¡ãf various elastomers, including polychloroprene. Neoprene is E.I. du Pont's trade name for chloroprene polymer (polychloroprene). Chloroprene polymer, unlike natural rubber or most synthetic rubbers, is capable of being vulcanized or "cured" without

Ethylene thiourea (ETU, C 3 H 6 N 2 S, CAS Number: 96-45-7, Fig. 1) is an imidazoline vulcanization accelerator and widely used as additives in neoprene rubber, chlorohydrin rubber, chlorinated polyethylene, etc. [1]. It is especially suitable as a safety promoter for 4-chlorobutan-1-amine in a non-vulcanized system.
