Aramid Fiber Used for Aquos Zero Smartphone

Aquos Zero

Technora Black, Teijin Limited’s strong and flame-retardant para-aramid fiber, is being used in the back panel of the newest Aquos Zero, Sharp’s flagship smartphone model that was released on December 21st.

This new waterproof smartphone weighs just 146 g and is the world’s lightest smartphone in a class of 6-inch screen and battery capacity rated above 3,000 mAh. The plastic back panel is reinforced with Technora Black, and the frame is made of magnesium alloy.

Teijin’s Technora para-aramid fiber is eight times stronger than steel and is highly heat- and shock-resistant, making it an ideal material for a broad range of applications from rope, timing belts, racing car seats and car hoods to spacecraft. Technora Black is increasingly being used for outdoor applications, such as firefighting clothing and yacht sails, owing to its weather resistance driven from its color by adding black pigments to Technora in the spinning process.

Aramid fiber reinforced plastic is expected to contribute to the development of advanced, extra-high-speed mobile devices thanks to its light weight, electric insulation and dielectric constant property for minimized electromagnetic interference. Technora Black’s weather resistance and attractive appearance, in addition to its many core features, makes it especially suitable for smartphones.
