A method of making a molded article. The method includes introducing into a mold a composition including thermoplastic particles with hollow microspheres attached to their outer surfaces, rotating the mold, and heating the mold at a temperature at which the thermoplastic particles melt. The hollow microspheres are included in the molded article. Molded articles are also disclosed. A powder composition that includes thermoplastic powder particles and hollow ceramic microspheres attached to outer surfaces of at least some of the thermoplastic powder particles is also disclosed. The hollow ceramic microspheres are either adhered to the outer surfaces of at least some of the thermoplastic powder particles with a liquid or embedded in the outer surfaces of at least some of the thermoplastic powder particles.
