Product Description
Product Description
PA66 homopolymer is produced by the polymerization of hexamethylene diamine and adipic acid (a dibasic acid). PA66 is a semicrystalline-crystalline material with one of the highest melting points among commercially available polyamides. The grades have strength and stiffness that is retained at elevated temperatures. PA66 does absorb moisture after molding, but retention is not as high as PA6. Moisture absorption depends on the composition of the material, wall thickness, and environmental conditions.
Dimensional stability and properties are all affected by the amount of moisture absorption, which must be taken into account for product design. Various modifiers are added to improve mechanical properties; glass is one of the most commonly used fillers. The addition of elastomers, such as EPDM or SBR, improves impact resistance.
Although it does not flow as easily as PA6, the viscosity of PA66 is low so it flows easily, which enables the molding of thin
components. The viscosity is very sensitive to temperature.
Shrinkage is of the order of 0.01–0.02 mm/mm [1–2%]. The addition of reinforcing glass fibers reduces the shrinkage to 0.2–1%.
Differential shrinkage in the flow and cross-flow directions is quite high. Mineral fillers yield more isotropic moldings.
PA66 is resistant to most solvents, but not to strong acids or oxidizing agents.
