Bridgestone invents a new type of tire material Bridgestone claims that this new type of polymer has "unprecedented durability" and is comparable to ordinary rubber. Its crack resistance exceeds 5 times, its abrasion resistance exceeds 2.5 times, and its tensile strength is 1.5 times higher than that of natural rubber. .
The newly developed "high-strength rubber" (HSR) is called a hybrid material: A synthetic rubber component such as butadiene and isoprene is bonded to a resin component such as ethylene at the molecular level.
The production process is formed by copolymerization using Bridgestone's proprietary Gd catalyst. The company stated that it has developed polymers by "further developing" Gd catalyst technology for synthesizing polyisoprene rubber. The company says that this next-generation material can combine the flexibility of rubber with the high strength of the resin.
Bridgestone invents high-strength rubber material as a sustainable material
Bridgestone also pointed out that the application of the target includes higher performance and less material development than current tires. The company also expects that HSR will help it achieve its 2050 reusable 100% sustainable material target.
In this case, "sustainable materials" are resources that originate from continuous supply, can be used for a long period of time, and have low environmental and social impacts throughout the life cycle from procurement to disposal.
Readings:Tungsten FDG Contanier for nuclear medical
Tungsten Alloy Shielding for radioactive nuclide injection is a device used to protect medical personnel and patients from radioactive nuclide radiation. It is made of tungsten alloy, which can effectively shield the radiation of radioactive nuclides while maintaining the flexibility and operability of the syringe. Tungsten alloy shielding can reduce the radiation dose of radioactive nuclides during the injection process, thereby reducing the radiation risk for medical personnel and patients. In addition, tungsten alloy shielding also has corrosion resistance and wear resistance, which can be reused and reduce the cost of medical equipment.
