Injection molded nylon Pa66 side arms Biology essay
NylonPolyamide PA is a plastic composed of polyamide resins. Such resins can be made from diamines and dibasic acids by condensation, or from lactams formed by dehydration of amino acids by ring-opening polymerization. There are many variants of PA, mainly PA6, PA66, PA610, PA11, PA12, PA1010, PA612, PA6, or is a polymer made of hexamethylenediamine, while PA66, or, is made of adipic acid and hexamethylenediamine. PA is generally harder than PA6 PA PA has similar chemical and physical properties. However, PA has a lower melting point and a wider range of process temperatures. PA Nylon injection molding technique. Feature: Basically, there are PA PA66, or nylon has tenacious and wearable, self-lubricating and slippery properties with non-toxic and antibiosis and high water absorbability. In addition, its tensile strength and stiffness will be greatly reduced,
