Polyamide 6.6 PA66
(DIS)ADVANTAGES OF POLYAMIDE 66
Advantages
- tough, strong, impact resistant
- low coefficient of friction
- good resistance
to abrasion, high temperatures, solvents and bases
- processable by thermoplastic methods
Disadvantages
- high moisture absorption with dimensional instability
loss of up to 30% tensile strength and 50% of tensile modulus
- subject to attack by strong acids and oxidizing agents
- requires UV stabilization
- high shrinkage in molded sections
- electrical and mechanical properties influenced by moisture content
- dissolved by phenols
