Z-Fold3 Aramid Fiber Case

If add this UPGRADE We will use the internal Aramid Fiber shell (well known as Kevlar reg . brand of Dupon’s) to produce your Back Case.

Indestructible and fully functional. It doesn’t interfere with phone signal.

Mechanical properties: Aramid yarn has a breaking tenacity of 3045 MPa, in other words more than 5 times than this of steel (under water, aramid is 4 times stronger) and twice than this of glass fiber or nylon. High strength is a result of its aromatic and amide group and high crystallinity. Aramid retains strength and modulus at temperatures as high as 300 degrees Celcius. It behaves elastically under tension. When it comes to severe bending, it shows non-linear plastic deformation. With tension fatigue, no failure is observed even at impressively high loads and cycle times. Creep strain for aramid is only 0.3%.

To sum up, aramid general characteristics are:

• High strength
• Resistance to absorption
• Resistance to organic solvent, good chemical resistance
• No conductivity
• No melting point
• Low flammability
• Excellent heat, and cut resistance
• Sensitive to acids and ultraviolet radiation
