Polyamide. Polyamide (PA) is a polymer, which contains recurring amide groups (R—CO—NH—R') as integral parts of the main polymer chain. From: Advances in Textile Biotechnology, 2010 Related terms Polyamide, any polymer (substance composed of long, multiple-unit molecules) in which the repeating units in the molecular chain are linked together by amide groups. Amide groups have the general chemical formula CO-NH. They may be produced by the interaction of an amine (NH2) group and a carboxy
As nouns the difference between polymer and polyamide is that polymer is (organic chemistry) a long or larger molecule consisting of a chain or network of many repeating units, formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization, the joining of many monomer molecules while polyamide is.. Polyamideimide (PAI) Properties. Polyamideimides (PAIs) are high performance amorphous engineering thermoplastics of yellow to brown color. They have outstanding thermal, mechanical, and chemical properties and are often the best choice for demanding applications where very high mechanical strength, stiffness and low friction in combination with high temperature, corrosion, and wear resistance. The polymer known as nylon 6,6 takes the form of a salt, and when this salt is heated, it becomes molten. Once a polyamide fabric manufacturer has obtained this molten material, it is passed through a metal spinneret with a process called extrusion

.. Guest Blog by Dr. Robert Humphreys Bio-polyamides have been available commercially since the first half of the 20th Century, when Rilsan®11 was first introduced1. Image at left are Rilsan®HT connectors (source: Arkema). Since then, other partly or fully bio-sourced polyamides have been commercialized for a range of applications. Properties, formulation and applications of bio-polyamides hav Polyamide is a polymer, which means that the fibers are made of several molecules linked together, creating a long chain. It is created as a liquid at first, which is then spun and dried into single fibers. The process is a bit longer and takes a lot more resources, time and it also costs quite a bit, which is why jackets that are made of this.
