These engineering polymers are thermoplastics that repeat amide groups on the molecular chains.They have good chemical and temperature resistance,provide strength,toughness,stiffness,and resist wear and abrasion.The largest nylon market today,with more than 40% of the total demand,is in automobiles and transportation equipment.Recently,the use of plastics in under-the-hood parts increased dramatically and nylon is by far the most widely use plastics for this purpose thanks to its temperature and good chemical resistance.
