[14] calculated the activation energy of the neat PA66 at various heating rates, and found that the activation energy gradually increased with the heating rate from low to high.
In low concentrations (less than [approximately equal to] 30% w/w), PA66 readily dissolves in the formic acid containing the solvent mixture at room temperature, but for higher concentrations, the solution should be agitated for a longer time.
However, almost no PA66/graphene composites were reported owing to the difficulty of in situ polymerization of PA66 and the poor dispersion of graphene in the PA66 matrix.

Invista will launch its new Torzen High Viscosity PA66 resins at Fakuma, as the company continues to develop a portfolio of engineered PA66 resins aimed at solving today's marketplace needs.
The PA66 grade Ultramid A3WG10 CR is reinforced with 50 percent glass fibers and is therefore exceptionally rigid and solid, even at high temperatures.
Chapter 1 provides a presentation and analysis of the global market for polyamide (PA6 and PA66), including forecasts up to 2022: revenues development as well as production and demand volumes are analyzed.
"At KET we had originally planned to develop the parts using nylon PA66 because of its good mechanical properties, but PA66 could not meet the OEMs electrical resistance requirements under high temperature testing conditions"--minimum 500 MOhm at 120[degrees]C and DC 500V).
The switch housing is made of PA66, and used silver-alloy contacts for better continuity conduct and long life cycles.
