Polyolefin dispersions, froths, and foams and articles manufactured therefrom are disclosed. Also disclosed is a method for generating a thermoplastic foam from an aqueous dispersion. The aqueous dispersion may include a thermoplastic resin, water, and a stabilizing agent. The method may include adding at least one frothing surfactant to the aqueous dispersion to form a mixture, adding a flame retardant and/or a phase change material, frothing the mixture to create a froth, and removing at least a portion of the water to produce the foam. Se dan a conocer dispersiones, esponjas, y espumas de poliolefina, y artículos fabricados a partir de las mismas. También se da a conocer un método para generar una espuma termoplástica a partir de una dispersión acuosa. La dispersión acuosa puede incluir una resina termoplástica, agua, y un agente estabilizante. El método puede incluir la adición de cuando menos un tensoactivo espumante a la dispersión acuosa para formar una mezcla, la adición de un retardante de flama y/o un material de cambio de fase, la espumación de la mezcla para crear un espumado, y la remoción de cuando menos una porción del agua para producir la espuma.
