What Kind Of Insoluble Sulfur Are Commonly Used In The Rubber Industry?What Kind Of Insoluble Sulfur Are Commonly Used In The Rubber Industry?

Sulfur is a common mineral in nature which has very important medicinal value. In the rubber industry, sulfur also play an important role–vulcanizing agent in rubber products. The sulfur used in the rubber industry includes sulfur powder, insoluble sulfur, colloidal sulfur, precipitated sulfur, sublimed sulfur, deacidified sulfur, and non-crystalline sulfur. Between them, the first three kinds of sulfur are more […]

10 Precautions For Using Insoluble Sulfur10 Precautions For Using Insoluble Sulfur

Due to some advantages of insoluble sulfur, insoluble sulfur has been widely used in the production of tires and other rubber composite products. However, in the use of insoluble sulfur, the following matters need to attention: (1) Insoluble sulfur is converted to soluble sulfur (β sulfur) when exposed to certain alkaline materials. (2) Insoluble sulfur will be […]

How To Improve Product Quality According To Mixing Accelerators?How To Improve Product Quality According To Mixing Accelerators?

In order to further improve the vulcanization speed and achieve a comprehensive and high value in use, two or three accelerators are often used in the design of the vulcanization system in the rubber formula to receive the advantages of complementing each other or activating each other, thereby adapting to the processing technology and need to […]

The Market Development Of DOTPThe Market Development Of DOTP

DOTP (Dioctyl terephthalate) is an excellent primary plasticizer for polyvinyl chloride (PVC) plastics. Compared with the currently used dioctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, difficulty in volatilization, resistance to extraction, softness and electrical insulation. Meanwhile, it has excellent durability resistant to soapy water and low temperature softness in products. Because […]

What Is Insoluble Sulfur?What Is Insoluble Sulfur?

Insoluble Sulfur (IS) is polymeric sulfur. Insoluble Sulfur is insoluble in carbon disulfide, water, and rubber, but evenly dispersed in the rubber mixture, and does not spray the surface during cooling and storage of the rubber. So it is called Insoluble Sulfur or Polymeric Sulfur.   Compared with ordinary sulfur, Insoluble Sulfur has the following advantages: (1) The rubber which containing Insoluble Sulfur does not bloom during the storage period. Insoluble Sulfur can maintain uniform composition and performance; overcome the shortcomings […]

Protective System Products Of Rubber AdditivesProtective System Products Of Rubber Additives

Rubber or rubber products are affected by various external factors during processing, storage and use, and will gradually lose their original excellent performance, and eventually lose their use value. This phenomenon is called rubber aging. The characteristics of rubber aging: First, the appearance of the material changes, such as: the material becomes sticky, soft, hard, […]

A short introduction about the commonly used antioxidantA short introduction about the commonly used antioxidant

Rubber and its products in the long-term storage and use process, due to heat, oxygen, ozone, constant metal ions, mechanical stress, light, high-energy rays role, and other chemicals and the role of the mildew, gradually reduce so that they lose the original physical and mechanical properties of process known as aging. With the aging process […]

What should we pay attention to when using rubber antioxidant?What should we pay attention to when using rubber antioxidant?

Because the protective effect of each type of rubber antioxidant has its limitations,the aging of rubber products in actual use is affected by many factors, so the choice of rubber antioxidant should note the following points: Firstly, due to the different characteristics of each rubber antioxidant, different rubber formulation has different aging properties. Therefore, the most effective […]

The common rubber accelerators in producing rubberThe common rubber accelerators in producing rubber

There are thousands of species of rubber chelating agent used in the production , the role of them in the rubber is also very complex, not only determines the mechanical properties of vulcanized rubber and products performance and life expectancy effect, and also influence the melt processing technology performance and semi-finished products processing quality, the […]

How to choose the rubber antioxidantHow to choose the rubber antioxidant

Due to the different types of rubber and vulcanization way, you need to choose a different rubberantioxidant, how to choose the rubber antioxidant – for a few classes of rubber below: 1 For NR, SBR’s antioxidant Selecting antioxidant should consider the heat resistance of the rubber, ozone resistance, flex resistance considerations, with well-sustained stability antioxidant. 2 For NBR antioxidant NBR, the better the effect of […]
