Built for the world your hardware actually faces.
Start with the design problem: the impact your part must absorb, the vibration it must isolate, the environment it must survive. Find it below, see the material do the job, then spec your part.
◆Helmet liner test
Helmet liner impact test.
A helmet with our elastomer as the liner under the shell, on a 5 kg head. Choose the liner density and thickness, how far the impact falls and how many times, and see how hard the head is jolted compared with a typical closed-cell helmet foam.
Liner density
Densities used in the SDSU helmet liner study.
Number of hits
How hard the head is jolted, every hit
EstimatePeak head acceleration, first hit
Lower is safer
Compared with closed-cell foam
Peak, last hit
Head Injury Criterion (HIC)
Try a thinner liner, a higher drop or more hits, and see what changes.
How these results are made
These are estimates from a published San Diego State University study of our elastomer as a helmet liner: a 5 kg head, a 100 mm impact area and a 20 mm liner, struck after a 1 m drop. At those settings the study reports a peak head acceleration of 60 g (low density, predicted), 69 g (medium) and 80 g (high), against 126 g for a typical closed-cell helmet foam. Other drop heights, thicknesses and repeated hits are scaled from those results. A real helmet depends on its shell, fit and the standard it must meet, so our design team runs a full finite element analysis (FEA) of your own design.
Find your design problem.
Engineers come to us with one of four problems. Each links to the tests and demonstrations that match it.
Drop and impact protection
Energy absorption · peak transmitted force · stroke
Keep peak force or g level under a limit when the part is dropped or struck. Tune density and thickness for the energy and the stroke you have.
Repeated impact
Under 20% loss after 7 impacts · 98% recovery
Parts that take hit after hit, like helmet liners, footwear and handling bumpers. Our elastomer recovers its shape and keeps most of its load-bearing capacity after repeated strikes.
Vibration isolation
Frequency range · transmissibility · mounted mass
Reduce vibration reaching sensors, electronics or cargo. Geometry tuning for a target frequency band is in development; share your frequency range and mass to see what we can test today.
Battery and thermal protection
Impact · fire retardant · temperature range
Cushion cells against impact while adding fire retardant and thermal performance in the same cast part, instead of stacking separate layers.
Or find your market.
Five markets we work in today. Select one to filter the demonstrations below.
See it take a hit.
EV passenger battery protection
Concept for a single cast battery tray that absorbs impact energy before it reaches the cells. Internal demonstration; crash performance is qualified for each vehicle program.
Drone body protection
A drone body cast in our elastomer in place of a multi-part assembly. In this demonstration it takes the impact, recovers its shape and keeps flying.
Portable battery unit protection
Impact protection for portable battery units that get dropped, thrown in vehicles and carried in the field.
E-scooter battery protection
Impact protection around e-scooter battery modules. Internal demonstration; results depend on the pack and the load case.
Helmet protection
A helmet liner under the shell. Try the helmet liner test above for estimated peak head acceleration against closed-cell foam.
Walking shoe comfort
Cushioning in walking shoes, where the material is loaded step after step.
Protecting boxes in transport
Box corners that absorb drops and road vibration in transit.
Videos show internal demonstrations. Performance for your part is confirmed against your load case in FEA and on a sample.
What we need to spec your part.
You don’t need a material datasheet. Rough answers to these questions are enough to start.
Your hardware next
Bring your load case. Rough numbers are fine.
Tell us the impact or vibration, the envelope and the environment. Our part spec form captures it and hands it to an engineer on our team.
