Get PriceNylon 46 was primarily developed to have a higher operating temperature than other grades of nylon Production and processing Polyamides are typically made by combining two monomers namely adipic acid with 1 6 diaminohexane Once these two monomers have reacted together they form water as a by product of each polymer chain linkage
Get PriceNylon is made when the appropriate monomers the chemical building blocks which make up polymers are combined to form a long chain via a condensation polymerisation reaction The monomers for nylon 6 6 are adipic acid and hexamethylene diamine The two molecules are combined to create the polymer and water H 2 O is produced as a by product
Get PriceProcessing starts with understanding the resin and providing correct preparation If you are dealing with nylon or other moisture sensitive resins that have the possibility of undergoing hydrolysis during processing you must dry the resin Hydrolysis means the moisture will react with and degrade the polymer chain making it shorter
