A low glass transition temperature (Tg) extrusion grade for use in food and medical packaging as a discrete layer in multilayer film. It has a low glass transition temperature, and provides excellent clarity, stiffness, water vapor barrier and good thermoformability. TOPAS 9506F-04 is especially recommended for use in blown films due to its higher molecular weight and increased melt strength for better bubble stability. TOPAS is an amorphous copolymer based on the polymerization of ethylene and nor-bornene using metallocene catalysts. Its property profile can be varied over a wide range by adjusting the chemical structure during polymerization. Information provided by Polyplastics. |
