Recently, the Teijin Group announced that it has successfully developed 'PLANEXT®' films that incorporate gasoline-resistant and formative door handles for smart entry systems, using proprietary polymer modification and film-forming technologies.
The newly developed film after the processing of special metal deposition technology manufacturers to achieve the replacement of chrome-plated metal deposition film mass production, and by Honda Lock.Mtg.Co., Ltd. developed intelligent access to the system door Used by the handle.
Smart car door handle
In recent years, more and more car door locks tend to be intelligent, and the smart entry system that can be locked and unlocked by only touching the door handle by hand is being continuously developed.
In the smart entry system, in order to prevent the sensor failure door handle part of the non-conductive, but usually chrome-plated door handle due to the surface of the conductive, it is not suitable for intelligent access system. On the other hand, non-conductive Metal vapor-deposited films have been actually adopted as automobile exterior applications. However, the door handles require both strict gasoline resistance and formability, and therefore, metal vapor-deposited films have not been adopted for door handles.
In this context, Teijin has successfully developed PLANEXT® SN4600, which combines gasoline resistance and formability with mass production through the modification of its proprietary biodegradable polymer, PLANEXT®, using polymer modification technology.
In addition, Teijin has developed 'PLANEXT® SN4600' films for automotive exterior applications including door handles using special film-forming techniques.
'PLANEXT ® SN4600 ' film
The PLANEXT® SN4600 membrane developed this time is an improvement on PLANEXT®'s chemical resistance, transparency and high-level through the modification of plant-derived bio-plastic PLANEXT® from plant-derived isosorbide Surface hardness and other characteristics, but also have excellent resistance to gasoline, good formability and weathering.
This film can be used even in the case of self-service gas stations where the driver's hands are easily contaminated with gasoline, and in design and processing, it is possible to deal with complicated molding shapes by optimizing the heat resistance and the film forming conditions to improve the formability. In addition, in order to protect the base material, this film is given a UV protection function to improve weather resistance and discoloration of the base material due to UV light.
In the future, Teijin will be the film for the automotive components market actively propose to expand its use, looking forward to expanding its sales.
