What is the difference between modified nylon and standard nylon?

Modified nylon is a type of nylon that has been enhanced with additives or reinforcement materials like glass fibers, minerals, or other compounds to improve its properties, such as strength, heat resistance, chemical resistance, or impact resistance. Standard nylon, on the other hand, refers to pure nylon (like PA6 or PA66) without these modifications, offering good basic mechanical properties but lacking the specialized enhancements of modified versions. In summary, modified nylon provides higher performance for specific applications, while standard nylon is more general-purpose.
