Polyamide (PA)

Polyamide (PA) is a generic name for a family of synthetic polymers first produced in February 1935 by Wallace Carters at DuPont. Due to the binding of repetitive peptamide units, in addition to thermal resistance, these materials also have high electrical resistance and due to their crystalline structure, they show good chemical resistance. Other properties mentioned for nylons include impermeability; at the same time, by mixing, the flammability of these materials can be easily increased. Polyamides are widely used in the automotive and transportation industries, electricity and electronics, textiles, packaging and home products. By adding glass fibers and increasing the strength of these materials, they can also be used as suitable alternatives for metal parts, and therefore polyamides can be considered the first and most important engineering polymer.
