Polymer nanocomposites, particularly polymer-silicate nanocomposites, represent an emerging class of specialty plastic materials.
The melt-processing route is a powerful approach in the manufacture of these compounds. As a result of the “nano”-sized dispersion, reinforcement efficiency is realized at low loading levels (3-5%) which is a small cost in terms of specific gravity.
Dramatic enhancements are observed in heat distortion temperature and stiffness. Other benefits include: lower gas permeability, good surface appearance, dimensional stability, and lower heat release.
