Abstract:
In at least one embodiment, a plastic article comprises a first plastic layer having a periphery and defining a cavity. An expanded polymer particle core is formed in-situ and heat-bonded to the cavity. The expanded polymer particle core has an apparent bulk density ranging from 1 lb/ft3 to 20 lb/ft3. The article supports a dynamic load or static load exceeding 1.3 lbf/in2.
