CAS 105-55-5 Accelerator DETU;Diethyl-thiourea

Name: Accelerator DETU
CAS:105-55-5
Usage: This product is a thiourea accelerator. This type of accelerator belt has low promotion efficiency and poor scorch resistance, so diene rubber is rarely used. However, in special circumstances, such as when vulcanized with sulfur donors such as thiuram sulfide, this product has The role of activator. Thiourea accelerators have unique effects on the vulcanization of chloroprene rubber and can produce chloroprene vulcanized rubber with good properties such as tensile strength, hardness, and compression permanent deformation. Compared with NA-22, this product has faster scorching and vulcanization, but better vulcanization flatness. This product is easy to disperse and does not spray frost. When the dosage is large, high-temperature and high-speed vulcanization can be performed, and it is especially suitable for continuous vulcanization of extruded products. This product is also an accelerator for butyl rubber and a vulcanization activator for EPDM rubber. It can activate thiazole and sulfenamide accelerators in natural and styrene-butadiene rubber. It has antioxidant effects on natural, chloroprene, nitrile, and styrene-butadiene rubber. We are generally used to manufacture industrial rubber products, special wires, sponge products, etc. The general dosage in chloroprene rubber is 0.25~1 part. The dosage of natural rubber and styrene-butadiene rubber is 0.3~1.5 parts, combined with 0.3~1.5 parts of accelerator DM. This product is also used to prepare corrosion inhibitor Rodine31A.

Physical and chemical properties: Easily soluble in ethanol, acetone, and water, and insoluble in gasoline. Hygroscopic.
Safty: This product is non-toxic. This product should be stored in a cool, dry, and well-ventilated place. Packaged products should be kept out of direct sunlight.
