Advantages of Polyamide
High strength over wide temperature
range, up to 450°F (232°C). Chemical
resistant except strong acids or bases.
- Homopolymer
- Processability, Good
- Stiffness, Good
- Food Contact Acceptable
- Impact Resistance, Good
- Copolymer
- Impact Resistance, High
- Flow, High
- Chemically Coupled
Disadvantages of Polyamide
Parts are subject to warp due the
shrink difference parallel and perpendicular
to fill and a high shrink base resin. Molded
parts in your application can absorb moisture,
changing dimensions and mechanical
properties. Price is moderate to high.
- 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).
