The EFM case armour range provides protection for iPhones from 5 through 7, and the Samsung Galaxy S7 and S7 Edge. Putting the "armour" in the name, these cases use D30 technology which is an impact protection solution arising from the 2006 Winter Olympics.
EFM has announced an exclusive partnership with D30 allowing its injection-moulded impact protection smart material to be used in its smartphone cases across Australia and New Zealand. The first models in production are the EFM Aspen Case Armour and EFM Monaco Wallet Case Armour, which will be available in a range of colours – orange, jet black, mint, violet, navy and slate.
EFM states its case armour for iPhone 7 and 7 Plus offers up to 107% greater impact protection compared to its competitors. Product and Brand manager Duane Cubbage said, "I am genuinely excited to release the lightest, slimmest, D30 injected, high impact protective case range in the market."
The way D30 technology works is via non-Newtonian physics, stating in standard conditions the molecules flow freely allowing the material to remain soft and flexible. On impact they lock together, dissipating the impact energy and reducing the force transmitted, but then instantly return to their flexible state. The stronger the impact the more the molecules react and the better the protection.
All EFM cases undergo a lab-controlled drop test from one metre high, measuring the amount of force produced when the case hits the bottom, with the lower its impact force the higher the impact resistance. EFM's cases are rated at impact rating level 9, measuring at 2.250 – 2.49 kn.
The full range including pricing is online at EFM's website.
To help me understand how the D30 technology worked, EFM posted a sample of the material for me to play with, which you can see in this video.
