Bridgestone Corp. (TYO:5108) has discovered a technique for monitoring and measuring strain-induced crystallization in natural and isoprene rubber at a record-high temporal resolution. The basic technology for this was developed using Spring-8, a large synchrotron radiation facility in western Japan. Natural rubber is less susceptible to cracking than typical isoprene rubber, with one suspected reason for this being the crystallization...

Inoac to Roll Out High-Performance Elastomer Developed by US-Based Cooper Standard
Inoac Corp. is poised to launch the new material Fortrex in Japan within this year. A high-performance elastomer developed by Inoac’s global partner U.S.-based Cooper-Standard Holdings Inc., Fortrex combines the advantages of thermoplastic vulcanizate (TPV) and ethylene propylene diene monomer (EPDM), and will be sold as Japan’s first superelastomer of its kind. In the U.S., Fortrex is used in automotive...
Sumitomo Chemical Develops New EPDM Grade for Rubber-to-Metal Adhesion
Sumitomo Chemical Co. Ltd. (TYO:4005) has developed a new grade of ethylene propylene diene monomer (EPDM) for rubber-to-metal adhesion, coming as part of a broader company effort to develop various new grades of EPDM. The development of this new grade was achieved via a random arrangement of ethylene and propylene. Sumitomo Chemical is now sending samples of the grade to...
