Abstract

Se revela una composicion de polímero multimodal para tubos, así como los tubos que se fabrican con este material. El polímero es un polietilenomultimodal que tiene una densidad de entre 0,930 y 0,965 g/cm3, y una viscosidad en un esfuerzo cortanted e 747 Pa (eta (747Pa) de, por lo menos, 650 Pa.s;dicho polietileno multimodal comprende una fraccion de homopolímero de etileno de bajo peso molecular (BPM) y una fraccion de copolímero de etileno dealto peso molecular (APM), dicha fraccion de APMti ene una relacion del peso de la fraccion de BPM y la de APM de (35-55):(65-45). Con preferencia,el polietileno multimodal tiene una viscosidad en un esfuerzo cortante de 2,7 kPa (eta(2.7kPa)) de entre 260 y 450 kPa.s; y un índice deadelgazamientopor cortante (IAC) que se define como la relacion de las viscosidades en el punto de esfuerzos cortantes de 2,7 y 2,10 kPa, respectivamente, de IAC(2.7/210)= 50-150; y un modulo de almacenamiento (G) en un modulo de pérdida (G) de 5kPa, de G(5kPa >/= 3 .000 Pa. El tubo se fabrica con la composicionde polímero multimodal y soporta un esfuerzo de 8,0 MPa durante 50 anos a 20*C (RMR 8,0). Con preferencia, el tubo tiene una propagacion de grietarápida (PGR) de valor S4, segun sedetermina de acuerdo co n la norma ISO 13.477:1997 (E), de -5*C o inferior y una resistencia a la propagacion degrieta lenta, que se determina segun la norma ISO 13.479: 1997, de, por lo menos, 500 horas a 4,6 MPa/80*C. La composicion de polímero leaporta buenaspropiedades anti-pandeo al tubo que se confecciona con ésta.
