Sumitomo Rubber Industries Ltd. (TYO:5110) has managed a world-first success in shedding light on the crystallization process that occurs at the tips of cracks in natural rubber – crystallization referring here to rubber molecules becoming aligned in the direction of elongation when the rubber is stretched. The company’s research on this was carried out in conjunction with the Leibniz Institute...
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...
The Research Association of Nano Structured Polymer recently held the 12th TPE Technology Institute Open Seminar, which was host to lectures on three topics. First to present was Sadaharu Hashimoto, R&D manager at Zeon Corp.’s (TYO:4205) R&D Center. His presentation, titled “Development of Novel Elastic Materials: Asymmetric Triblock Styrene Copolymer,” previously received an award from the Society of Polymer Science,...
