Developing High-Impact Materials AMILAN™ (Nylon) and TORAYCON™ (PBT) to Contribute to Vehicle Safety and Weight Reduction

Safety measures for the driver, passengers and pedestrians.
This high-impact grade made using NANOALLOY™ technology helps to improve safety by reducing damage in the event of a collision.


Toray has succeeded in significantly improving impact resistance by using our proprietary innovative microstructure control technology (NANOALLOY™ in our PBT/PC resin polymer alloy.
TORAYCON™ uses this NANOALLOY™ technology to achieve significantly improved impact resistance compared with conventional materials and other resins. This grade can absorb high levels of force and can resist deforming at high speeds, and is used in crash boxes to improve impact absorption in front, side and rear collisions.

A range of three different grades of TORAYCON™ with NANOALLOY™ is available: the standard 8207X01 grade; a grade with superior hydrolysis resistance; and a colored grade with excellent weather resistance.

In addition, U118G-40 resin is an AMILAN™ elastomeric alloy with excellent impact resistance while maintaining the high rigidity of glass fiber-reinforced products. It is already in use in the market, in airbag retainers.

Toray’s elastomeric alloy AMILAN™ and TORAYCON™ with NANOALLOY™ help to protect passengers through the use of passive safety technology. If you are looking for impact-absorbing materials, be sure to consider Toray’s high-impact grades AMILAN™ and TORAYCON™.

Finally, we will continue to propose resolutions to a variety of solutions to the problems that designers are faced with by using simulations such as flow analysis and impact analysis.
For impact analysis, we verify the reproducibility of the simulation by comparing and verifying the results of the CAE analysis against actual equipment test results. This enables designers to optimize their designs using CAE to shorten development time.
