Standard Veriflex
is a two-part, fully formable thermoset shape memory polymer
(SMP) resin system with very unique “memory” properties.
Heated above its activation temperature, Veriflex changes from
a rigid polymer to a very elastic state. In this elastic state,
it can be twisted, pulled, bent, and stretched, reaching up
to 200% elongation. If cooled while constrained in the new
shape, the polymer hardens and can maintain its deformed configuration
indefinitely. When heated above its activation temperature
again, this polymer returns to the shape in which it was cured.
This process can be repeated indefinitely without loss of
the memory shape or degradation of the material.
Thermochromic Veriflex is only available
in the styrene-based version of the resin and allows for easier
use and functionality of the cured resin. When the thermochromic
version of Veriflex has reached its transition temperature,
it changes color to signal its readiness to be molded, shaped,
and formed. This eliminates possible problems with heating
the material too much or not enough.
Both standard and thermochromic Veriflex
resins are engineered with a glass transition temperature
(Tg) of 62° C.

Veriflex is characterized by triggering
segments. At a temperature above Tg (Tform)
the material can be easily deformed. The deformed shape will be
maintained when the material is cooled below the Tg (Tcool).
The material will "remember" or return to its original
shape when it is heated to a temperature above the Tg
again. The material should be manipulated while in its fully elastic
state, which is above the temperature transition range shown below.
