| PBS-4 is a certified prime grade Impact copolymer specially designed for extrusion of sheet for thermoforming of food packaging applications. PBS-4 combines good thermal stability with good melt strength, good Toughness and Stiffness, optimal stability of melt that minimizes potential sheet thickness variations, and very good organoleptic properties. PBS-4 other applications include injection molding of household goods, food containers and medical articles. PBS-4 complies with FDA regulation 21CRF 177.1520 (a)(3)(i) / (c)3.1+3.2, and most international regulations concerning the use of Polypropylene in contact with food.&& |
