benchmark for new elastomer compounds. weinheim, july 10, 2023. freudenberg’s new development for the vulcanization of chloroprene rubber eliminates the need for ethylene thiourea (etu) as an accelerator while still meeting the strict requirements of the automotive industry. with this innovation, the company follows its own sustainability.
ethylene thiourea wikipedia,ethylene thiourea (etu) is an organosulfur compound with the formula c3h6n2s. it is an example of an n,n-disubstituted thiourea. it is a white solid. it is synthesized by treating ethylenediamine with carbon disulfide. [3] ethylene thioureas are an excellent accelerant of vulcanization of neoprene rubbers. in commercial use is the n,n.
a safer alternative replacement for thiourea based
ethylene thiourea (etu)-based accelerators have been the industry standard for speeding the vulcanisation process (acting as an accelerator). however, etu has now been classified as a suspected human carcinogen by various eu bodies. its use is expected to be restricted or prohibited by the eu in the near future.
rubber raw materials european rubber journal,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.
china rubber accelerator etu manufacturer, suppliers, factory price
as a professional china rubber accelerator etu manufacturer and suppliers, we supply rubber chemical, rubber additive as well as prepared rubber products with good price. the product should be stored in the dry and cooling place with good ventilation,avoiding exposure of the packaged product to direct sunlight.
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.
etu-free compound from freudenberg sealing,- rubber world
this was verified after the corresponding preconditioning with 7 days at 70 °c (158 °f) in grease, 10 days at 80 °c (176 °f) in water and 48 hours in 70 °c (158 °f) hot air. substituting the harmful accelerator ethylene thiourea in the cross-linking of chloroprene rubber is only one benefit offered by the new elastomer compound.
new-generation curative taking an etu replacement accelerator.lanxess’ rubber additive hpca-50 and rubber additive mtt-80 provide an alternative to ethylene thiourea (etu), an ultra-accelerator frequently used to cure polychloroprene (cr) and other diene rubbers. due to the high toxicity of etu, extensive efforts have been made to replace etu in rubber compounds.
updated: freudenberg claims etu-free elastomer advance
weinheim, germany freudenberg sealing technologies (fst) has announced a new development for the vulcanisation of chloroprene rubber that eliminates the need for ethylene thiourea (etu) as an accelerator. the development, the company claimed 10 july, “sets a benchmark for new elastomer compounds,” and meets the strict requirements of.
ethylene thiourea c3h6n2s cid 2723650 rubber accelerator,ethylene thiourea is used in the rubber industry and in the production of some fungicides. no information is available on the acute (short-term) or chronic (long-term) effects of ethylene thiourea in humans. in rodents chronically exposed to ethylene thiourea in their diet, effects on the thyroid have been observed.
- 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:
- 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.
