How Does D3O® Impact Protection Work?
The D3O® technology is based on non-Newtonian principles. In standard conditions, the molecules flow freely allowing the material to remain soft and flexible, but on impact, they lock together to absorb impact energy and reduce the force transmitted. The molecules instantly return to their flexible state. The raw material is strain rate sensitive which means the stronger the impact, the more the molecules react, and the better the protection. D3O manufactures this raw substance into practical functioning foam and non-foam materials.
To test their impact resistance, EFM cases undergo a lab-controlled drop test. This involves dropping the phone with the case on from a height of 1m, then measuring the amount of impact force produced when the case hits the bottom. The lower the case’s impact force, the higher its impact resistance, which also means a higher impact rating.
D3O® Impact Protection Material
EFM Case Armour are the first impact protection products to utilise injection moulding to integrate D3O® impact protection material into the design, as well as being the first range to include coloured material, available in Jet Black, Slate, Navy, Violet, Mint and Orange.
