Abstract

La presente descripción proporciona tubos compuestos de PTFE extruido con un coeficiente de fricción (COF) reducido. En algunas modalidades, esos tubos compuestos de PTFE extruido pueden exhibir un cambio reducido en el coeficiente de fricción entre aproximadamente 20°C y aproximadamente 40°C con la inclusión de partículas poliméricas secundarias con tamaños de partícula pequeños (< 100 µm) a porcentajes de carga menores de aproximadamente de 50% en peso.
