Abstract
Official abstract text for this publication.
A formulation includes a polymeric material, a nucleating agent, and a surface active agent. The formulation can be used to form an insulated container.
First claim
Opening claim text (preview).
The invention claimed is: 1. An insulative cellular polypropylene-based extruded material comprising i) a first polymer material comprising at least one high melt strength polypropylene homopolymer, ii) a second polymer material comprising at least one polymer selected from the group consisting of crystalline polypropylene homopolymer, impact polypropylene copolymer, and mixtures thereof, iii) at least one nucleating agent, and iv) at least one slip agent, wherein the extruded material has a cell aspect ratio in a cross direction of about 2.75 to about 3.75, a cell density of about 800,000 cells/in 3 and wherein the extruded material extruded through an extruder die lip at a die exit angle of 20° to 60° lacks surface indentations of greater than 5 microns when a sheet of the extruded material is curved to form a round article. 2. A micro-creasing or macro-creasing insulative cellular polypropylene-based extruded material having a cell density of about 700,000 cells/in 3 to about 2,000,000 cells/in 3 and a cell aspect ratio in a machine direction of about 2.75 to about 4.5, and wherein the extruded material extruded through an extruder die lip at a die exit angle of 20° to 60° lacks surface indentations of greater than 5 microns when a sheet of the extruded material is curved to form a round article. 3. The micro-creasing or macro-creasing insulative cellular polypropylene-based extruded material of claim 2 , wherein the cell density is about 900,000 cells/in 3 to about 2,000,000 cells/in 3 and the cell aspect ratio in a cross direction is about 2.75 to about 4.5.
