Resin impregnated,
continuous glass fibers are drawn through a curing die of a specific cross section, yielding consistent quality,
dimensions and mechanical properties to provide more consistent spring rates than alternate materials.
Processing conditions can cause material properties to shift from the values stated in the information.

This software is used to
predict the material behavior during this process
and, as a result, we can provide the potential
weight reduction, mechanical properties of the final
foamed part, and recommendations for optimal tool
design*.

Because the trays were regularly handled by consumers
and filled with food, it was very important that any
changes made to the material would not jeopardize the
packaging’s FDA compliance.
The sheet producer began experimenting with material
changes in-house, but struggled to achieve consistency
of release.
