the chemical&physical properties of pa6 are similarto those of pa66, however, it has a lower melting point&a widerange of process temperatures. its impact resistance&solubilityare better than pa66, but its moisture absorption is stronger.because many of the characteristics of plastic parts aresubject to moisture absorption, so the use of pa6 design productsshould take full account of this. in order to improve themechanical properties of pa6, a variety of modifiers are oftenadded.
