etu (ethylene thiourea) rubber accelerator: characteristics
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.
quickly and safely getting up to speed - cordis,since the percentage of srm102 required compared to rubber content is similar to that of etu, the new additive is expected to have minimal effect on the final manufacturing cost. saferubber has delivered a safe and cost-effective alternative to the carcinogenic rubber vulcanisation accelerator additive etu.

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.
updated: freudenberg claims etu-free elastomer advance.the development, the company claimed 10 july, “sets a benchmark for new elastomer compounds,” and meets the strict requirements of the automotive industry. etu accelerators have been used to cure chloroprene rubber for decades: enhancing low-temperature flexibility and resistance to media such as greases and lubricants.

- 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 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 accelerator in rubber vulcanization?
- An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- 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.
- 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 a conventional curing system for elastomers?
- Typical conventional curing systems for various elastomers are given below: This term is used for natural rubber, polyisoprene and butadiene based synthetic rubber compounds, when very low dosages of sulfur (below 0.4-0.5 phr) and higher dosages of accelerators (2.5 to 5.0 phr) are used.
