JOURNAL FREE ACCESSNatural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), isoprene rubber (IR) and butyl rubber (IIR) are called general purpose rubber. NR is agricultural products produced in Southeast Asia. Other rubbers are manufactured using radical polymerization, anionic polymerization or cationic polymerization. General purpose rubbers are widely used in the industrial field such as materials for tire. In the case of materials for tire, recently, the development of rubber with reduced hysteresis losses is strongly desired from the viewpoint of resource saving and energy saving. For this purpose, various kinds of solution-polymerized SBR (S-SBR) are developed. The remarkable technology of S-SBR is to be able to introduce the functional group into polymer terminal. This modification technology is effective for reducing hysteresis losses. Therefore, the development of new modified SSBR will be carried out in future.View full abstractDownload PDF (2540K) -

JOURNAL FREE ACCESSSpecial-purpose rubbers have been developing with progress of automotive technology. The consumption of theses rubbers are increasing with the expansion of the world automotive market. Current applications and properties of some typical rubber like EPDM, NBR, CR, ACM, FKM, HNBR were explained in this review. Market of these rubbers will be growing up with its superior properties from now though required properties will be changed by progress of technology.View full abstractDownload PDF (2437K) -

JOURNAL FREE ACCESSA liquid rubber shows fluidity at room temperature, but it becomes solid rubber by a chemical reaction with a hardening agent. And it shows the dynamic property that is similar to cross-linked rubber. A liquid rubber has some merit in comparison with the general rubber. For example, processing is easy or the energy that is needed is small. Therefore, application development of liquid rubber advances in various fields, and the demand is spreading.
In this report, I classified liquid rubbers according to the kind of the main chain, and explained it about characteristic of each liquid rubber, applications and demand trend.View full abstractDownload PDF (4130K) -

JOURNAL FREE ACCESSRecent advances in Thermoplastic Elastomer in Japan are described, and trends of application, market and material development in the future are also forecasted.
TPEs global market is growing with 8-10%/year in this decade. Although the growing rate in Japan is not so high as that in the world, the trend will succeed also in Japan.
Especially, TPOs and hydrogenated TPSs (SEBS, SEPS) are growing very fast. TPOs based on metallocene catalyzed technology is very unique. Many TPOs of which structure (tacticity, narrow molecular weight distribution and block sequences) is well regulated, are developed for automotive materials, sheets and films applications. Also blend type of TPOs, especially TPVs have been well developed and commercialized.
Many grades of hydrogenated TPS are developing. The wide applications of the low and middle molecular weight type of hydrogenated TPS are thermoplastic modifier, adhesive, and compatibilizer for TPV, engineering plastics and polymer blends. High molecular weight type of hydrogenated TPS are well used for TPS elastomer compound which is used for automotive, liner cap of beverage, medical bag and medical tube. TPVs are growing because of its heat stability and oil resistance. New types of TPV named super-TPV are also developing. The global growth of TPE will be continued for next decade.View full abstractDownload PDF (9774K) -
