Reduced density hollow glass microsphere polymer composite

A shaped structural article formed by melt processing of a thermoplastic composite comprising a dispersion of a glass

• particulate and a fiber in a continuous thermoplastic polymer, wherein the thermoplastic composite comprises:
• (a) a glass particulate having a particle size greater than about 5 microns,
• (b) a fiber,
• (c) a coating of an interfacial modifier on the fiber and the glass particulate;
• and
• (d) a polymer phase, wherein the interfacial modifier coating on the particulate and the fiber allows for greater freedom of movement of the particulate within the polymer phase of the composite, the percentages based on the composite.

A thermoplastic composite comprising a dispersion of a glass particulate and a fiber in a continuous thermoplastic polymer, the thermoplastic composite comprises:

• (a) a glass particulate having a particle size greater than 5 microns;
• (b) a fiber, and
• (c) a polymer phase;
• wherein the particulate and the fiber have a coating comprising about 0.005 to 8 wt.-% of an interfacial modifier, wherein the interfacial modifier coating allows for greater freedom of movement of the particles within the polymer phase of the composite;
• and, the percentage based on the composite.
