It is resistant to mechanical influences, its properties do not change even in aggressive conditions (for example, when interacting withPMM or hydrocarbons). Some disadvantages of polyamide of this brand are its hygroscopicity, that is, the ability to absorb moisture, therefore it is not used in the manufacture of elements that are used in a humid environment. But at the same time, after complete drying, the part of polyamide 6 completely restores all its original characteristics.
