Nylon 6/6 is one of the most versatile engineering thermoplastics. It is popular in every major market using thermoplastic materials. Because of its excellent balance of strength, ductility and heat resistance, nylon 6/6 is an outstanding candidate for metal replacement applications. Nylon 6/6 is very easy to process with a very wide process window. This allows it to be used for everything from complex, thin walled components to large thick walled housings.

Advantages of Polyamide
Impact (some grades) and wear resistant. Flexible, can have very high elongation before breaking. Resistant to acids and bases.
- Homopolymer
- Processability, Good
- Stiffness, Good
- Food Contact Acceptable
- Impact Resistance, Good
- Copolymer
- Impact Resistance, High
- Flow, High
- Chemically Coupled
Disadvantages of Polyamide
It is sensitive to thick sections in your part which may cause voids, bubbles or sink. Poor dimensional accuracy. Low mechanical and thermal properties. Poor resistance to organic solvents. Price is low to very low.
- Degraded by UV
- Flammable, but retarded grades available
- Attacked by chlorinated solvents and aromatics
- Difficult to bond
- Several metals accelerate oxidative degrading
- Low temperature impact strength is poor
Background of Polyamide
Polyamide (Nylon) polymer was first commercially introduced by DuPont as a result of the significant research work of W. H. Carothers in the 1930s, who was conducting early extensive research efforts in polyesters and polyamides. The first important polyamide was Nylon 66 produced by the reaction of adipic acid (a 6-carbon dibasic acid) and hexamethylene diamine (a 6-carbon aliphatic diamine).
