Dilatant Impact Protection Material (aka D3O) - Soft material with very high shock absorption properties


This material has shear-thickening or dilatant properties, which means the elasticity varies depending on the force it is subjected to. It is soft and flexible when moved slowly, but when moved quickly – for example, when compressed by an impact – its molecules lock together, thereby absorbing and dispersing the force of impact.

Applications for dilatant foam:

It is incorporated into a number of products, including back protectors, shoulder pads, elbow pads, and knee pads for motorcycling, mountain biking, winter sports, and personal protection. It is also used in protective sleeves and casings for computers and mobile phones.


There is a range of sheet products and standard components available; these vary in thickness, composition, and protective characteristics. Customised components can be moulded to specific requirements.

The sample:

You can choose between:
- a 16.5 cm x 9.5 cm sheet
- a ~5 cm x ~5 cm piece 

Both samples have a thickness of 4 mm.  

All samples come with a laminated information card, which includes contact details for the supplier.
