Rubber-based blends tire industry

In conclusion, rubber-based blends are promising materials that can be designed to fulfill the requirements necessary for various types of applications— from medical devices and biomedical applications, to packaging applications, military and aerospace applications, tire industry applications, and structural applications. The chapter also addresses a new trend in the field of rubber-based product development— recycling old parts into powders and incorporating them in different matrices. 

Natural rubber/cw-1,4-polybutadiene (NR/BR) blends (70/30 mass ratio) have been widely used in the tire industry. Many nanocomposites based on organo-montmorillonite (OMMT)/rubber blends have been investigated. However, relatively little attention had been paid to binary rubber hybrids/ montmorillonite nanocomposites, and according to Zheng Gu et ah, no studies existed dealing with OMMT/NR/BR nanocomposites. So, the authors described the preparation of OMMT/NR/BR nanocomposites by direct mechanical blending and determined the cure characteristics, static mechanical properties, dynamic mechanical properties, and thermal stability of the nanocomposites. OMMT/NR/BR nanocomposites had exactly the same onset decomposition temperature and lower thermal degradation rate as the NR/BR blends. 

Proprietary rosin oil blends are used mainly in the tire industry and in belting as a less expensive alternative to using more expensive phenolic tackiflers with aromatic process oil. Rosin oil functions both as a tackifier and as a processing oil for rubber compounds usually based on general-purpose elastomers. As discussed earlier, environmental concerns are now associated with the use of aromatic oils.
