Moisture-resistant barrier material based on copolyamide PA-6, I/6, T/6, 6 and/or PA-6, I/6, T which is capable of being processed by drawing and/or thermoforming |
摘要 |
The present invention relates to materials which are barriers to gases and to liquids, which are resistant to water and which are capable of being shaped into single- or multimaterial thin layers or films which can be processed by drawing and/or thermoforming. These barrier materials are based on copolyamide composed essentially of units derived from hexamethylenediamine, iso- and terephthalic acids and optionally adipic acid.They can be used for the manufacture of composite materials comprising one or more thin layers, sheets and/or films, pipes or hollow bodies intended in particular for the packaging of chemicals, foodstuffs or pharmaceutical and/or cosmetic products.
