EMS-Grivory Grivory® G 25 PA6I/6T
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 6 (PA6)
Material Notes:	Product description: Grivory G 25 is a very high viscous amorphous copolyamide. It is suitable for injection stretch blow molding, injection blow molding, extrusion blow molding, the manufacture of coextruded blown film and mono-or coextruded cast film and coextrusion of tubes. Grivory G 25 is also used as an additive for polyamide 6 and different copolyamides to improve film properties. The key properties of Grivory G 25 are: High transparency and high surface gloss Very good chemical resistance Very good abrasion resistance Excellent flavor and aroma barrier Improved gas and aroma barrier at elevated relative humidity Low transmission of UV radiation Application examples: Barrier layer for mono- or coextruded rigid packaging (EBM or ISBM bottles), barrier tubes, barrier layer in multilayer films for flexible food and cosmetics packaging, barrier layer modifier for flexible meat/cheese or other food packaging.
