Continued decline in prices of butadiene and synthetic rubber
Continued decline in prices of butadiene and synthetic rubber Prices in Asian markets fell again as demand for butadiene declined and concerns about oversupply increased. Synthetic rubber (SBR) also saw a significant drop in prices this week. Platts: The decline in demand for butadiene in Asian markets has again led to a drop in the price of this product, but it seems that there are signs of a decline in the price of this product in the current situation, and this has prevented a sharp fall in prices. Weakening demand for butadiene has been driven by declining purchases from downstream manufacturers, especially ABS and SBR. The Chinese government has taken a tough line this year for manufacturers of polymer and rubber products to deal with environmental pollution, which has led to limited production of these products and reduced demand for butadiene. As a result of this trend, concerns have…
What are the differences between SMR20 and synthetic rubber ?
The difference between natural rubber and synthetic rubber In 1839, an American inventor named Charles Goodyear developed a method to improve the properties of natural rubber, making it stronger and more usable. He called this process the vulcanization or boiling of oxygen in rubber and metals. This process revolutionized the rubber industry. Natural rubber is an elastomer (elastic hydrocarbon polymer) made from raw rubber, a milk colloid obtained from most plants. Elastomer is a material that can withstand more elastic deformation than other materials under stress and return to its original size without any deformation. The commercial source of natural rubber is a native Brazilian plant called Hoya brazilensis, which belongs to the Euphorbia family. Some other plants from which natural rubber can be obtained are: gutta-percha, rubber-shaped, Panamanian rubber tree, common dandelion and Russian dandelion. Natural rubber was used commercially until the twentieth century. Natural rubber has occupied an…
Synthetic rubber
What is synthetic rubber ? Since synthetic rubber is produced through the process of vulcanization (heating rubber with sulfur), the rubber produced is called vulcanized rubber. There are other synthetic rubbers made from other compounds.To produce rubber, they first make a slit in the trunk of the rubber tree, then collect the white leachate that comes out of it in small cups. At the collection point, the leachates are protected after rinsing with ammonia solution. The leachate obtained from the rubber tree is removed over time, through the coagulation process and by the addition of acids or salts. During this process, the rubber separates from the liquid in the form of a white paste, and then it is rolled and dried using a roller, and finally, these sheets are exported to different countries. Because raw rubber does not have high elastic properties, sulfur is added to it through a vulcanization…
