Rubber Accelerators

<br>Taizhou Huangyan Donghai Chemical Co.,Ltd.was founded in March 1985, we are one of the batch of township enterprises established since Chinau2019s reform and opening up. We were formerly known as Huangyan Donghai Chemical Plant, and were renamed as Taizhou Huangyan Donghai Chemical Co., Ltd. in 2005 with a registered capital of RMB11.3 million. In 2002, we passed the ISO90001: 2000 quality certification. In June 2010, we were licensed as Zhejiang Rubber Auxiliary Testing Center and passed the ISO14001:2004 Quality Certification in July the same year.

Presentation Transcript

  1. Rubber Accelerators Rubber accelerator M (MBT) Chemical Name: 2-thiol benzothiazole Traits Light yellow powder, slightly odor, bitter and non-toxic. The specific gravity is 1.42-1.52, and the melting point is above 170°C. It is easily soluble in ethyl acetate, acetone, sodium hydroxide and sodium carbonate dilute solution, soluble in ethanol, but not soluble in benzene. Insoluble in water and gasoline, stable storage. Package Composite bag, net weight 25 kg.

  2. Accelerator DM（ （MBTS） ） Chemical Name：2.2'-Dibenzothiazole disulfide Molecular weight：332.5 Use Commonly used in natural rubber and various synthetic rubbers. It can produce flat and medium-speed vulcanization, and the vulcanization temperature is higher. If it is not shared with furnace carbon black, scorching will not occur. Safe operation, easy to disperse without pollution. Vulcanized rubber is resistant to aging and can be used for white or colored rubber products. Because of its bitter taste, it is not suitable for food rubber products. It can be used to make tires, hoses, rubber shoes, rubber cloth and other general industrial products. DM can act as a plasticizer or retarder in neoprene.

  3. Accelerator NS（ （TBBS） ） Chemical Name：N-tert-butyl-2-benzothiazole sulfenamide Use：It is widely used in natural rubber, synthetic rubber and its products. The tire industry is particularly suitable for radial tires. Product performance 1、In natural rubber, styrene butadiene rubber, butadiene rubber, it has good staging performance, excellent rubber compound performance, good vulcanization flatness, and long Mooney scorch time. 2、Vulcanized rubber has high physical and mechanical properties and is an ideal all-in-one vulcanization accelerator. When used in different rubber varieties, its hardness, elongation, tensile stress and permanent deformation are better than other products.

  4. Accelerator TETD Chemical Name：Tetraethylthiuram disulfide Molecular weight：296.54 Traits：White crystalline powder, odorless, tasteless and non-toxic. Specific gravity 1.17-1.30, soluble in acetone, benzene, toluene, carbon disulfide and chloroform, slightly soluble in ethanol and gasoline, insoluble in water, dilute acid and dilute alkali, stable storage.

  5. Accelerator NOBS（ （MOR MBS MDZ） ） Chemical name: N-Oxydiethylene-2-benzothiazole sulfenamide Technical index :GB8829-88 Properties:Light yellow small granules or powder. Easily soluble in dichloromethane and acetone; soluble in benzene, carbon tetrachloride, ethyl acetate and ethanol; slightly soluble in gasoline; insoluble in water. It will decompose gradually if heated.
