PORON® Materials for Protective Cases
Impact Protection for Portable Electronics
With portable electronics being designed smaller and becoming a larger part of our lives, protection for
these devices has never been so important.
Impact Protection
Excellent Impact Protection
Drop Height vs. Impact Force
Rogers’ PORON® foams are made of an intricate network
of viscoelastic polymer bonds. These bonds are able to
both store and dissipate energy when the energy is
transferred to the foam through a shock or impact. Most
impacts excite a wide range of frequencies throughout a
system. PORON polyurethane foams are able to damp
these frequencies and prevent the resulting energy
from traveling through the device and damaging internal components, electronics and screens.
PORON foams are available in a variety of densities and
formulations. As we can see from the Impact Protection
graph, Rogers’ low density grades of impact protection
foam reduce the force of impact by over 50%.
Note: Low Mass Impact Tester, 30.6 g brass ball at varying drop
Color Selection
Color Options Available
Black is the standard color for PORON industrial grade
foams, but over 125 color offerings are available. Different colors give designers more flexibility on the placement of the foam within or on the outside of the protective cases. Contact your Rogers’ Customer Service Representative or Sales Engineer for color availability for
specific PORON material grades.
Colors! Note: The color availability of PORON® foams depends on the
formulation grade, density and thickness.

Compression Set
Consistent and Reliable Performance
Compression set testing indicates how a material will
perform in an application while compressed over a long
period of time.
Two Rogers’ foams and a competitive material were
measured for thickness and then aged for 22 hours at
50% compression in a 70°C oven. After aging, the
heights of the materials were recorded. PORON materials lost between 4-5% of their total height while the
competitive material collapsed and only returned to
half of its original height.
Aged Performance
The SEM images below show a clear image of the difference between PORON foams and the competitor material.
Reliable Impact Protection Over Time
The decrease in thickness over time in the competitive
material will affect its ability to provide impact protection. On average, Competitor A impact protection will
decrease 37% while PORON foams will only decrease
between 3-8% depending on the grade of material.
