PAs

PAs (polyamides) are a family of semi-crystalline thermoplastic polymers characterized by repeating amide linkages in their backbone chain. Commonly known as nylons, these materials are produced in numerous variants (PA6, PA66, PA11, PA12, etc.) that offer a balance of strength, stiffness, and toughness with good chemical resistance and low friction properties. PAs are widely used in automotive, mechanical, and consumer applications where durability and dimensional stability are critical, and they are often selected over metals in cost-sensitive designs where weight reduction and ease of processing are valued.
