Polyamide (PA)

PA (Polyamide) is a semi-crystalline polymer.
There are two types: those made of one basic material (e.g. PA 6) and those made of two basic materials (e.g. PA 66). They can occur both naturally (e.g. wool and silk) and synthetically (e.g. nylon).

Polyamides have excellent mechanical properties and can be either hard and tough or soft and flexible. They absorb moisture and have excellent slide and wear characteristics. Polyamides are commonly used in the textile and automotive industry.

More Information on polyamide


  • History

    • 1930s: Beginning of methodical research of polyamides with the development of an industrial process for polyamide 6.6 (nylon) by W.H. Carothers and Polyamide 6 (perlon) by P.Schlack.
    • 1940: Beginning of production
    • Between 1956-1965: Production increased significantly when highly stabilised polyamides (which could easily be processed) were developed
    • Since 1965: a number of refinements have been made including glass fibre reinforced polyamide compounds which are flame retardant.
