Abstract
Se describe una espuma de resina de polímero de propileno, extruida que comprende una resina de polímero de propileno que presenta una viscosidad extensional, biaxial de por lo menos 3.0 x 10 a la 6 poises a una tension extensional, biaxial de 0.2 y un índice alfa de endurecimiento por deformacion, biaxial de por lo menos 0.25, el índice alfa de endurecimiento por deformacion, biaxial está definido por la siguiente formula: alfa = 0.77 x (log n 2 - log n 1) en la que n 1 representa la viscosidad extensional, biaxial a una tension extensional, biaxial de 0.01 en n 2 representa la viscosidad extensional, biaxial a una tension extensional, biaxial de 0.2, la espuma contiene una vasta pluralidad de celdas, y tiene un espesor de por lo menos 20 mm, una densidad de 0.005 a 0.03 g/cmü, un diámetro de celda promedio de 0.4 a 2.0 mm y una relacion de celda cerrada de por lo menos 80%. La espuma de resina de la presente invencion no solamente tiene peso ligero, sino también exhibe alta eficacia de acojinamiento y excelente resistencia mecánicas, de tal manera que después de fabricarse en diversos tamaños por corte, los artículos de la espuma de resina resultante pueden ser utilizados ventajosamente en los campos de materiales de embalaje acojinado, materiales flotantes y materiales aislantes del calor.
