::summary Impact-protection equipment company ::

D3O is the namesake ingredient brand of British company D3O Lab, specializing in rate-sensitive impact protection technologies based on dilatant materials, also known as viscoelastic or shear thickening materials.

The brand focuses on designing and adding materials, including set foams, formable foams, set elastomers, and formable elastomers. to various products to improve their flexibility, durability, or impact-protection compared to unarmored, hard-armored, or foam-armored products.

D3O is sold in multiple countries, it is used in sports and motorcycle gear, protective cases for consumer electronics, industrial workwear, and military protection, including helmet pads and limb protectors. Competitors also producing viscoelastic armor pads include RHEON, SAS-TEC, Knox MicroLock and TF impact armor.

History

In 1999, the materials scientists Richard Palmer and Philip Green experimented with a dilatant fluid with non-Newtonian properties. The fluid was free-flowing at rest but became instantly hard upon impact.

Palmer and Green drew inspiration from snowboarding and decided to replicate its matrix-like quality to develop a flexible material that incorporated the dilatant fluid. After experimenting with numerous materials and formulas, they invented a flexible, pliable material that locked together and solidified in the event of a collision.

When incorporated into clothing, the material moves with the wearer while providing protection similar to rigid armor and superior to foam armor when hit.

In 1999, A patent application was filed.

D3O was used commercially for the first time by the United States Ski Team and the Canadian ski team at the 2006 Olympic Winter Games. D3O first entered the motorcycle market in 2009 when the ingredient was incorporated into CE-certified armour for the apparel brand Firstgear.

Philip Green left D3O in 2006. In 2009 Stuart Sawyer became interim CEO. Palmer took a sabbatical in 2010 and left the business in 2011, handing over full executive control to Sawyer. Sawyer remains in this position as of 2025.

In 2014, D3O was awarded £237,000 by the Technology Strategy Board—now known as Innovate UK—to develop a shock absorption helmet system prototype for the defence market to reduce the risk of traumatic brain injury.

in 2015, the private equity & venture capital investor Beringea invested and D3O shifted towards product development and international marketing. D3O opened headquarters in London, which include test laboratories and house its global business functions.

The company began focusing more on the North American market and set up a new base of operations in the Virginia Tech Corporate Research Center (VTCRC) in Blacksburg, Virginia. Phone case manufacturer and business partner Gear4 became the UK’s number 1 phone case brand in volume and value.

In 2017, D3O became part of the American National Standards Institute (ANSI)/International Safety Equipment Association (ISEA) committee which developed the first standard in North America for protecting hands from impact injuries: ANSI/ISEA 138-2019

D3O was acquired in September 2021 by independent private equity fund Elysian Capital III LP from the previous owners, Beringea US & UK and Entrepreneurs Fund.

D3O applications

D3O is used in electronics (impact protection for phones, laptops, and other electronic devices), sports equipment, motorcycle riding gear, defence (helmets, armor, footwear) and industrial workwear (personal protective equipment such as gloves, knee pads and metatarsal guards for boots).

In 2020, D3O became the helmet suspension pad supplier for the US Armed Forces' Integrated Helmet Protection System (IHPS).

Product development

D3O uses its patents to create consumer goods and partner with various companies and government agencies.

In-house laboratories check that D3O products meet CE standards for sports and motorcycle applications, ISEA 138 for industrial applications, and the requirements of militaries and police forces.
