some commercially important thioureas include ethylene thiourea (etu), dipentamethylene thiourea (dptu), and dibutyl thiourea (dbtu). they are mainly used for the vulcanization of chloroprene rubbers. thiurams are very fast and effective sulfur cure accelerators. they can be used for all common unsaturated rubbers.
etu-free rubber compounds for freudenberg develops etu-free rubber compounds for,this is why freudenberg has developed new elastomer compounds that require no etu accelerator in the manufacture of products made of chloroprene rubber. one of the company’s successful applications of etu-free products in the automotive sector is in sealing bellows for joint seals in tie rods, control arms and wishbones.

- 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.
- 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 vulcanization process?
- Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur).
- Do secondary accelerators increase vulcanization speed?
- The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety. The dosages of the secondary accelerators are generally between 10-40% of the primary accelerator. Accelerators some times are also be classified according to the chemical groups to which they belong.
