    Abstract: Método para producir cuerpos moldeados planos con coeficientes de expansión térmica anisotrópicos a partir de composiciones poliméricas moldeables termoplásticas mediante carga de las composiciones poliméricas moldeables termoplásticas con filosilicatos laminares que tienen un diámetro en el rango de 10 a 1000 nm y una proporción de aspecto en el rango de 1 a 5 hasta 1 a 10000, extrusión de las composiciones poliméricas moldeables termoplásticas cargadas y subsiguiente dilatación uniaxial o biaxial del material extrudido para producir cuerpos moldeados planos o láminas, en cuyo caso los cuerpos moldeados extrudidos o dilatados, o las láminas se apilan una sobre otra para incrementar el grosor de capa, se comprimen o se laminan, y la preparación de cuerpos moldeados se efectúa a continuación por el método de extrusión o por termoconformado.
