Polyamide Tents

What is Polyamide?

“Nylons” refer to the group of plastics known as polyamides. They are basically polymer substances composed of a long and multiple numbers of molecules in which the repeating units are linked by amide groups.

These resins are available both naturally and also in artificial form.  Primarily naturally occurring polyamides comprise of proteins like wool & silk and artificially polymers are made by the process of polymerization or synthesis of materials like nylons, aramids & sodium poly (aspartate).

They provide a broad range of properties and uses especially used for the production of film & fiber and are also available for molding compounds.

They are used for a number of end segment applications including textiles, automotive, carpets, and sportswear due to their strength and durability.


It was first discovered in 1931 by W.H. Carothers while researching for polyesters & Polyamides. These nylons became commercial on the 28th October 1938 when they were introduced by DuPont.

The first kind of polymer produced was Nylon 66 by the reaction of adipic acid (a 6- carbon dibasic acid) and hexamethylene diamine (a 6- carbon aliphatic diamine).

In following years Polyamide (Nylon) became popular with usage in nylon stockings and till the late 1950s, they became a popular form of polymers being used on a large scale for a number of applications.


These plastic polymers inhibit unique and suiting properties for a countless number of applications. These properties include

  • PA has high heat stabilization ability
  • They are lubricated
  • Flame Retardant
  • Impact Modified
  • Chemically resistant

Polyamide Production Process and Capacity

Polyamide Production Process

It is formed by two methods. Two numbers arise from the first, in which the condensation reaction takes place between diamines & dibasic acids producing a nylon salt as a result.

The first number refers to carbon atoms in the diamine and the second one is the quantity present in the acid.

The second process involves opening up a monomer which contains both amine & acid group and is known as lactam ring. Its identity is based on the number of atoms present in the lactam monomer.

Applications & Uses of Polyamide

It is one of the largest engineering thermoplastic materials and finds its applications in several segments. These segments include:


These plastic polymers (PA 6) are often used to replace metal being used in automotive parts where there is an essential requirement of design, flexibility as well as temperature and chemical resistance.

It is commonly used to manufacture automotive parts like door handling, radiator grilles, airbag containers air-intake manifolds, relay boxes and engine covers etc.

Mostly PA is used to replace the metals in automotive parts due to its following properties:

Advantages & Disadvantages of Polyamide

These plastic materials are nowadays commonly used for a countless number of applications in different sectors. They have witnessed continuous growth in production and consumption in the recent years owing to its suitable properties.

It offers a number of advantages which make it an ideal choice for manufacturers. These benefits include:

  • Low coefficient of friction
  • High resistance to odd temperatures
  • Abrasion & chemical resistance
  • They are tough, strong with high impact resistance
  • Easy processability by thermoplastic methods.

Although they have a number of benefits, still there is a certain number of limitations associated with their usage. These limitations include:

  • They possess higher moisture absorption with dimensional instability
  • Require Ultra Violet stabilization
  • High shrinkage in molded sections
  • Moisture affects mechanical & electrical properties
  • Can be attacked by strong acids & oxidizing agents
  • They can even be dissolved by phenols.

What is the difference between the Polyester & Polyamide?

Both the synthetic fibers are highly torn- proof and resistant towards abrasion with low moisture absorption and also stretchy along with crease free.

PA polymers have the highest amount of resistance level as compared to all other raw materials (even if it is wet) and are very stretchy in nature whereas Polyester has excellent return conduct as it is very light. It can easily retain its shape along with resistance for sweat & UV rays.

Basic Differences

  • Polyesters carry ester functional group whereas, in PA, amide functional group is present.
  • Its monomer should have a carboxylic & an amine group, whereas polyesters should have a carboxylic group along with a hydroxyl group.
  • It is a thermoplastic kind of polymer but, polyesters can be thermoplastic or thermoset depending on their chemical structure.
  • They provide more natural feeling than the polyesters.
  • The polyester fabrics are more wrinkle resistant than these.
  • PA (Nylons) is always synthetic in nature but polyesters can be produced by natural ingredients also (like cutin obtained from plant cuticles).


Recycling of these polymers is essential as their presence in landfills can be dangerous, they may result in fire emitting hazardous gases in the environment.

The maximum usage of this polymer (especially PA6) is in carpets and they should be recycled to maintain a balance.

DuPont took an initiative in 1944 to recycle these carpets. It has started a program named The Carpet Reclamation Program where carpets are collected from 80 collection locations in The United States and they are recycled.

Different ways of Recycling

De-polymerization or chemical recycling – This method is used to disintegrate long chains into monomers that can be polymerized and again converted into a quality virgin polymer.

Extracting Recycling Or Recovery – This method is used to recover individual components from the polymeric mixture without gaining the monomer level.

Mechanical Recycling or Re-melting – It is done to perform melt-blending of the complete structure form and breakdown of melted polymeric form.

Thermal Recycling – In this process, only energy is recovered during the incineration of the polymer waste.

Applications of the Recycled form of Polymer

The recycled for of PA polymers can be reused for a number of uses such as carpet cushioning, automotive parts, roofing shingles, composite lumber, flooring material, highway noise abatement panels, packaging, and others.
