PA (Polyamid, Nylon)
PA is a semi-crystalline plastic whose natural color is milk white. Amorphous and transparent types are also produced. PA is characterized by great strength, toughness, and good storage properties.
The properties of PA are influenced by the degree of crystallization and the water content. Increasing water content and / or decreasing degree of crystallization result in lower strength properties but greater toughness.
There is good chemical resistance to organic solvents, but PA can easily be attacked by acids and oxidizing chemicals.
