Air Water Develops Highly Heat-Resistant FKM O-Ring

Air Water Inc. (TYO:4088) has developed a highly heat-resistant new O-ring using general-purpose fluororubber (FKM). This was achieved via efforts from subsidiary Air Water Mach Inc., which produces and and sells O-rings in addition to other sealing products. The new product combines fluororubber with Zeonano SG101, a series of single-walled carbon nanotubes that Zeon Corp. (TYO:4205) produces via the super-growth...

Bridgestone Makes New Discoveries in Monitoring, Measuring of Strain-Induced Crystallization in Rubber

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...
