D3O

D3O is a British technology and materials brand based in London, founded around 2001. The company develops and licenses specially formulated non-Newtonian materials for impact, shock, and vibration protection. The core is a flexible substance that hardens under pressure to absorb impact energy and then returns to its soft state.

D3O offers over 30 technologies, including foams and elastomers in solid or moldable forms. Applications are found worldwide – from sports and motorcycle protection to electronic cases, industrial workwear, and military uses such as helmet liners and body armor. Solutions include molded parts, sheets, and raw materials.
