Rigidified acrylics utilize a thermo formed acrylic shell that is
rigidified with fiberglass.  This hybrid process delivers higher
production volumes than fiberglass alone.  Rigidified Acrylics
offer excellent cost/performance benefits with tremendous overall
physical properties.  This process allows for a high degree of
design flexibility at moderate tooling costs.  If you are looking to
consolidate parts, rigidified acrylics may be an excellent choice
for your product.
